Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins. Most C2 domain proteins are either signal transduction enzymes that contain a single C2 domain, such as protein kinase C, or membrane trafficking proteins which contain at least two C2 domains, such as synaptotagmin 1. However, there are a few exceptions to this including RIM isoforms and some splice variants of piccolo/aczonin and intersectin which only have a single C2 domain. C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions. : Pssm-ID: 175980 [Multi-domain] Cd Length: 146 Bit Score: 225.65 E-value: 2.85e-68

Synaptic Ras-GTPase activating protein Pleckstrin homology (PH) domain; SynGAP is a member of the RasSynGAP family along with DOC-2/DAB2-interacting protein (DAB2IP) and neuronal growth-associated protein (nGAP/RASAL2). SynGAP, a neuronal Ras-GAP, has been shown display both Ras-GAP activity and Ras-related protein (Rap)-GAP activity. Saccharomyces cerevisiae Bud2 and GAP1 members CAPRI (Ca2+-promoted Ras inactivator) and RASAL (Ras-GTPase-activating-like protein) also possess this dual activity. Human DOC-2/DAB2-interacting protein (DAB2IP) is encoded by a tumor suppressor gene and a newly recognized member of the Ras-GTPase-activating family. Members here include mammals, amphibians, and bony fish. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

Ras-GTPase Activating Domain of proteins similar to neurofibromin; Neurofibromin-like proteins include the Saccharomyces cerevisiae RasGAP proteins Ira1 and Ira2, the closest homolog of neurofibromin, which is responsible for the human autosomal dominant disease neurofibromatosis type I (NF1). The RasGAP Ira1/2 proteins are negative regulators of the Ras-cAMP signaling pathway and conserved from yeast to human. In yeast Ras proteins are activated by GEFs, and inhibited by two GAPs, Ira1 and Ira2. Ras proteins activate the cAMP/protein kinase A (PKA) pathway, which controls metabolism, stress resistance, growth, and meiosis. Recent studies showed that the kelch proteins Gpb1 and Gpb2 inhibit Ras activity via association with Ira1 and Ira2. Gpb1/2 bind to a conserved C-terminal domain of Ira1/2, and loss of Gpb1/2 results in a destabilization of Ira1 and Ira2, leading to elevated levels of Ras2-GTP and uninhibited cAMP-PKA signaling. Since the Gpb1/2 binding domain on Ira1/2 is conserved in the human neurofibromin protein, the studies suggest that an analogous signaling mechanism may contribute to the neoplastic development of NF1.

The down-regulation of Ras by p120GAP is a critical step in the regulation of many cellular processes, which is disrupted in approximately 30% of human cancers. p120GAP contains SH2, SH3, PH, calcium- and lipid-binding domains, suggesting its involvement in a complex network of cellular interactions in vivo.

Ras-GTPase Activating Domain of IQ motif containing GTPase activating proteins; This family represents IQ motif containing GTPase activating protein (IQGAP) which associated with the Ras GTP-binding protein. A primary function of IQGAP proteins is to modulate cytoskeletal architecture. There are three known IQGAP family members: IQGAP1, IQGAP2 and IQGAP3. Human IQGAP1 and IQGAP2 share 62% identity. IQGAPs are multi-domain molecules having a calponin-homology (CH) domain which binds F-actin, IQGAP-specific repeats, a single WW domain, four IQ motifs that mediate interactions with calmodulin, and a RasGAP related domain that binds active Rho family GTPases. IQGAP is an essential regulator of cytoskeletal function. IQGAP1 negatively regulates Ras family GTPases by stimulating their intrinsic GTPase activity, the protein actually lacks GAP activity. Both IQGAP1 and IQGAP2 specifically bind to Cdc42 and Rac1, but not to RhoA. Despite of their similarities to part of the sequence of RasGAP, neither IQGAP1 nor IQGAP2 interacts with Ras. IQGAP3, only present in mammals, regulates the organization of the cytoskeleton under the regulation of Rac1 and Cdc42 in neuronal cells. The depletion of IQGAP3 is shown to impair neurite or axon outgrowth in neuronal cells with disorganized cytoskeleton. Pssm-ID: 213329 [Multi-domain] Cd Length: 331 Bit Score: 52.59 E-value: 6.96e-07

Ezrin was first identified as a constituent of microvilli, radixin as a barbed, end-capping actin-modulating protein from isolated junctional fractions, and moesin as a heparin binding protein. A tumour suppressor molecule responsible for neurofibromatosis type 2 (NF2) is highly similar to ERM proteins and has been designated merlin (moesin-ezrin-radixin-like protein). ERM molecules contain 3 domains, an N-terminal globular domain, an extended alpha-helical domain and a charged C-terminal domain (pfam00769). Ezrin, radixin and merlin also contain a polyproline linker region between the helical and C-terminal domains. The N-terminal domain is highly conserved and is also found in merlin, band 4.1 proteins and members of the band 4.1 superfamily, designated the FERM domain. ERM proteins crosslink actin filaments with plasma membranes. They co-localize with CD44 at actin filament plasma membrane interaction sites, associating with CD44 via their N-terminal domains and with actin filaments via their C-terminal domains. This is the alpha-helical domain, which is involved in intramolecular masking of protein-protein interaction sites, regulating the activity of this proteins.

Human IQGAP1 is most similar to mouse Iqgap1 (94% identity) and has 62% identity to human IQGAP2. IQGAP1 binds and cross-links actin filaments in vitro and has been implicated in Ca2+/calmodulin signaling, E-cadherin-dependent cell adhesion, cell motility, and invasion. Yeast IQGAP homologs have a role in the recruitment of actin filaments, are components of the spindle pole body, and are required for actomyosin ring assembly and cytokinesis. Furthermore, IQGAP1 over-expression has also been detected in gastric and colorectal carcinomas and gastric cancer cell lines. Pssm-ID: 213335 Cd Length: 380 Bit Score: 46.96 E-value: 5.43e-05

Bacillus thuringiensis crystal 6Aa (Cry6Aa) toxin, and similar proteins; This model includes pesticidal Cry6Aa toxin from Bacillus thuringiensis, one of the many parasporal crystal (Cry) toxins produced during the sporulation phase of growth. Many of these proteins are toxic to numerous insect species and have been effectively used as proteinaceous insecticides to directly kill insect pests; some have been used to control insect growth on transgenic agricultural plants. Cry6Aa exists as a protoxin, which is activated by cleavage using trypsin. Structure studies for Cry6Aa support a mechanism of action by pore formation, similar to cytolysin A (ClyA)-type alpha pore-forming toxins (alpha-PFTs) such as HblB, and bioassay and mutation studies show that Cry6Aa is an active pore-forming toxin. Cry6Aa shows atypical features compared to other members of alpha-PFTs, including internal repeat sequences and small loop regions within major alpha helices.

Growth-arrest specific micro-tubule binding; This family is the highly conserved central region of a number of metazoan proteins referred to as growth-arrest proteins. In mouse, Gas8 is predominantly a testicular protein, whose expression is developmentally regulated during puberty and spermatogenesis. In humans, it is absent in infertile males who lack the ability to generate gametes. The localization of Gas8 in the motility apparatus of post-meiotic gametocytes and mature spermatozoa, together with the detection of Gas8 also in cilia at the apical surfaces of epithelial cells lining the pulmonary bronchi and Fallopian tubes suggests that the Gas8 protein may have a role in the functioning of motile cellular appendages. Gas8 is a microtubule-binding protein localized to regions of dynein regulation in mammalian cells. Pssm-ID: 464001 [Multi-domain] Cd Length: 200 Bit Score: 45.28 E-value: 7.00e-05

Ras-GTPase Activating Domain of IQ motif containing GTPase activating protein 3; This family represents the IQ motif containing GTPase activating protein 3 (IQGAP3), which associates with Ras GTP-binding proteins. A primary function of IQGAP proteins is to modulate cytoskeletal architecture. There are three known IQGAP family members: IQGAP1, IQGAP2 and IQGAP3. Human IQGAP1 and IQGAP2 share 62% identity. IQGAPs are multi-domain molecules having a calponin-homology (CH) domain which binds F-actin, IQGAP-specific repeats, a single WW domain, four IQ motifs that mediate interactions with calmodulin, and a RasGAP related domain that binds active Rho family GTPases. IQGAP is an essential regulator of cytoskeletal function. IQGAP1 negatively regulates Ras family GTPases by stimulating their intrinsic GTPase activity, the protein actually lacks GAP activity. Both IQGAP1 and IQGAP2 specifically bind to Cdc42 and Rac1, but not to RhoA. Despite of their similarities to part of the sequence of RasGAP, neither IQGAP1 nor IQGAP2 interacts with Ras. IQGAP3, only present in mammals, regulates the organization of the cytoskeleton under the regulation of Rac1 and Cdc42 in neuronal cells. The depletion of IQGAP3 is shown to impair neurite or axon outgrowth in neuronal cells with disorganized cytoskeleton. Pssm-ID: 213346 [Multi-domain] Cd Length: 350 Bit Score: 45.59 E-value: 1.24e-04

UDM1 (ubiquitin-dependent DSB recruitment module 1) domain found in RING finger protein 168; RING finger protein 168 (RNF168) is an E3 ubiquitin-protein ligase that promotes noncanonical K27 ubiquitination to signal DNA damage. Together with RNF8, RNF168 functions as a DNA damage response (DDR) factor that promotes a series of ubiquitylation events on substrates such as H2A and H2AX. With H2AK13/15 ubiquitylation, it facilitates recruitment of repair factors p53-binding protein 1 (53BP1) or the RAP80-BRCA1 complex to sites of double-strand breaks (DSBs), and inhibits homologous recombination (HR) in cells deficient in the tumor suppressor BRCA1. RNF168 also promotes H2A neddylation, which antagonizes ubiquitylation of H2A and regulates DNA damage repair. In addition, RNF168 forms a functional complex with RAD6A or RAD6B during the DNA damage response. This model corresponds to the UDM1 (ubiquitin-dependent double-strand break [DSB] recruitment module 1) domain of RNF168, which comprises LRM1 (LR motif 1), UMI (ubiquitin-interacting motif [UIM]- and MIU-related UBD) and MIU1 (motif interacting with ubiquitin 1). Mutations of Ub-interacting residues in UDM1 have little effect on the accumulation of RNF168 to DSB sites, suggesting that it may not be the main site of binding ubiquitylated and polyubiquitylated targets.

1073-1146 | 5.17e-03 | ||||||||
Coiled-coiled domain of autophagy-related 16 (Atg16) family proteins; The Atg16 family includes Saccharomyces cerevisiae Atg16 (also called cytoplasm to vacuole targeting protein 11, CVT11, or SAP18), human autophagy-related protein 16-1 (also called APG16-like 1, ATG16L1, or APG16L) and autophagy-related protein 16-2 (also called APG16-like 2, ATG16L2, WD repeat-containing protein 80 or WDR80), and similar proteins. Atg16 stabilizes the Atg5-Atg12 conjugate and mediates the formation of the 350 kDa complex, which is necessary for autophagy. The Atg5-Atg12/Atg16 complex is required for efficient promotion of Atg8-conjugation to phosphatidylethanolamine and Atg8 localization to the pre-autophagosomal structure (PAS). Similarly, human ATG16L1 plays an essential role in autophagy and acts as a molecular scaffold which mediates protein-protein interactions essential for autophagosome formation. ATG16L2, though structurally similar to ATG16L1 and able to form a complex with the autophagy proteins Atg5 and Atg12, is not essential for autophagy. Single-nucleotide polymorphisms in ATG16L1 is associated with an increased risk of developing Crohn disease. Saccharomyces cerevisiae Atg16 contains an N-terminal domain (NTD) that interacts with the Atg5-Atg12 protein conjugate and a coiled-coil domain (CCD) that dimerizes and mediates self-assembly. Human ATG16L1 and ATG16L2 also contains an N-terminal region that binds Atg5, a CCD homologous to the yeast CCD, and a WD40 domain that represents approximately 50% of the full-length protein. This model corresponds to the CCD of Atg16 family proteins. Pssm-ID: 439196 [Multi-domain] Cd Length: 91 Bit Score: 37.55 E-value: 5.17e-03

RecF/RecN/SMC N terminal domain; This domain is found at the N terminus of SMC proteins. The SMC (structural maintenance of chromosomes) superfamily proteins have ATP-binding domains at the N- and C-termini, and two extended coiled-coil domains separated by a hinge in the middle. The eukaryotic SMC proteins form two kind of heterodimers: the SMC1/SMC3 and the SMC2/SMC4 types. These heterodimers constitute an essential part of higher order complexes, which are involved in chromatin and DNA dynamics.

RAS p21 protein activator (GTPase activating protein) 1 Pleckstrin homology (PH) domain; RASA1 (also called RasGap1 or p120) is a member of the RasGAP family of GTPase-activating proteins. RASA1 contains N-terminal SH2-SH3-SH2 domains, followed by two C2 domains, a PH domain, a RasGAP domain, and a BTK domain. Splice variants lack the N-terminal domains. It is a cytosolic vertebrate protein that acts as a suppressor of RAS via its C-terminal GAP domain function, enhancing the weak intrinsic GTPase activity of RAS proteins resulting in the inactive GDP-bound form of RAS, allowing control of cellular proliferation and differentiation. Additionally, it is involved in mitogenic signal transmission towards downstream interacting partners through its N-terminal SH2-SH3-SH2 domains. RASA1 interacts with a number of proteins including: G3BP1, SOCS3, ANXA6, Huntingtin, KHDRBS1, Src, EPHB3, EPH receptor B2, Insulin-like growth factor 1 receptor, PTK2B, DOK1, PDGFRB, HCK, Caveolin 2, DNAJA3, HRAS, GNB2L1 and NCK1. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

chromosome segregation protein SMC, primarily archaeal type; SMC (structural maintenance of chromosomes) proteins bind DNA and act in organizing and segregating chromosomes for partition. SMC proteins are found in bacteria, archaea, and eukaryotes. It is found in a single copy and is homodimeric in prokaryotes, but six paralogs (excluded from this family) are found in eukarotes, where SMC proteins are heterodimeric. This family represents the SMC protein of archaea and a few bacteria (Aquifex, Synechocystis, etc); the SMC of other bacteria is described by TIGR02168. The N- and C-terminal domains of this protein are well conserved, but the central hinge region is skewed in composition and highly divergent.

Guanylate-binding protein, C-terminal domain; Guanylate-binding protein (GBP), C-terminal domain. Guanylate-binding proteins (GBPs) are synthesized after activation of the cell by interferons. The biochemical properties of GBPs are clearly different from those of Ras-like and heterotrimeric GTP-binding proteins. They bind guanine nucleotides with low affinity (micromolar range), are stable in their absence, and have a high turnover GTPase. In addition to binding GDP/GTP, they have the unique ability to bind GMP with equal affinity and hydrolyze GTP not only to GDP, but also to GMP. This C-terminal domain has been shown to mediate inhibition of endothelial cell proliferation by inflammatory cytokines.

Sorting nexins (SNXs) are Phox homology (PX) domain containing proteins that are involved in regulating membrane traffic and protein sorting in the endosomal system. SNXs differ from each other in their lipid-binding specificity, subcellular localization and specific function in the endocytic pathway. A subset of SNXs also contain BAR domains. The PX-BAR structural unit determines the specific membrane targeting of SNXs. BAR domains form dimers that bind to membranes, induce membrane bending and curvature, and may also be involved in protein-protein interactions.
