Alpha subunit of G proteins (guanine nucleotide binding); The alpha subunit of G proteins contains the guanine nucleotide binding site. The heterotrimeric GNP-binding proteins are signal transducers that communicate signals from many hormones, neurotransmitters, chemokines, and autocrine and paracrine factors. Extracellular signals are received by receptors, which activate the G proteins, which in turn route the signals to several distinct intracellular signaling pathways. The alpha subunit of G proteins is a weak GTPase. In the resting state, heterotrimeric G proteins are associated at the cytosolic face of the plasma membrane and the alpha subunit binds to GDP. Upon activation by a receptor GDP is replaced with GTP, and the G-alpha/GTP complex dissociates from the beta and gamma subunits. This results in activation of downstream signaling pathways, such as cAMP synthesis by adenylyl cyclase, which is terminated when GTP is hydrolized and the heterotrimers reconstitute.

G-protein alpha subunit; G proteins couple receptors of extracellular signals to intracellular signaling pathways. The G protein alpha subunit binds guanyl nucleotide and is a weak GTPase. A set of residues that are unique to G-alpha as compared to its ancestor the Arf-like family form a ring of residues centered on the nucleotide binding site. A Ggamma is found fused to an inactive Galpha in the Dictyostelium protein gbqA.

ADP-ribosylation factor(Arf)/Arf-like (Arl) small GTPases; Arf (ADP-ribosylation factor)/Arl (Arf-like) small GTPases. Arf proteins are activators of phospholipase D isoforms. Unlike Ras proteins they lack cysteine residues at their C-termini and therefore are unlikely to be prenylated. Arfs are N-terminally myristoylated. Members of the Arf family are regulators of vesicle formation in intracellular traffic that interact reversibly with membranes of the secretory and endocytic compartments in a GTP-dependent manner. They depart from other small GTP-binding proteins by a unique structural device, interswitch toggle, that implements front-back communication from N-terminus to the nucleotide binding site. Arf-like (Arl) proteins are close relatives of the Arf, but only Arl1 has been shown to function in membrane traffic like the Arf proteins. Arl2 has an unrelated function in the folding of native tubulin, and Arl4 may function in the nucleus. Most other Arf family proteins are so far relatively poorly characterized. Thus, despite their significant sequence homologies, Arf family proteins may regulate unrelated functions.

178-276 2.13e-09

ADP ribosylation factor 6 (Arf6); Arf6 subfamily. Arf6 (ADP ribosylation factor 6) proteins localize to the plasma membrane, where they perform a wide variety of functions. In its active, GTP-bound form, Arf6 is involved in cell spreading, Rac-induced formation of plasma membrane ruffles, cell migration, wound healing, and Fc-mediated phagocytosis. Arf6 appears to change the actin structure at the plasma membrane by activating Rac, a Rho family protein involved in membrane ruffling. Arf6 is required for and enhances Rac formation of ruffles. Arf6 can regulate dendritic branching in hippocampal neurons, and in yeast it localizes to the growing bud, where it plays a role in polarized growth and bud site selection. In leukocytes, Arf6 is required for chemokine-stimulated migration across endothelial cells. Arf6 also plays a role in down-regulation of beta2-adrenergic receptors and luteinizing hormone receptors by facilitating the release of sequestered arrestin to allow endocytosis. Arf6 is believed to function at multiple sites on the plasma membrane through interaction with a specific set of GEFs, GAPs, and effectors. Arf6 has been implicated in breast cancer and melanoma cell invasion, and in actin remodelling at the invasion site of Chlamydia infection.

178-274 5.75e-07

ADP-ribosylation factor-1 (Arf1) and ADP-ribosylation factor-5 (Arf5); The Arf1-Arf5-like subfamily contains Arf1, Arf2, Arf3, Arf4, Arf5, and related proteins. Arfs1-5 are soluble proteins that are crucial for assembling coat proteins during vesicle formation. Each contains an N-terminal myristoylated amphipathic helix that is folded into the protein in the GDP-bound state. GDP/GTP exchange exposes the helix, which anchors to the membrane. Following GTP hydrolysis, the helix dissociates from the membrane and folds back into the protein. A general feature of Arf1-5 signaling may be the cooperation of two Arfs at the same site. Arfs1-5 are generally considered to be interchangeable in function and location, but some specific functions have been assigned. Arf1 localizes to the early/cis-Golgi, where it is activated by GBF1 and recruits the coat protein COPI. It also localizes to the trans-Golgi network (TGN), where it is activated by BIG1/BIG2 and recruits the AP1, AP3, AP4, and GGA proteins. Humans, but not rodents and other lower eukaryotes, lack Arf2. Human Arf3 shares 96% sequence identity with Arf1 and is believed to generally function interchangeably with Arf1. Human Arf4 in the activated (GTP-bound) state has been shown to interact with the cytoplasmic domain of epidermal growth factor receptor (EGFR) and mediate the EGF-dependent activation of phospholipase D2 (PLD2), leading to activation of the activator protein 1 (AP-1) transcription factor. Arf4 has also been shown to recognize the C-terminal sorting signal of rhodopsin and regulate its incorporation into specialized post-Golgi rhodopsin transport carriers (RTCs). There is some evidence that Arf5 functions at the early-Golgi and the trans-Golgi to affect Golgi-associated alpha-adaptin homology Arf-binding proteins (GGAs).

178-276 1.09e-06

ADP ribosylation factor 1 (Arf1); Arl1 subfamily. Arl1 (Arf-like 1) localizes to the Golgi complex, where it is believed to recruit effector proteins to the trans-Golgi network. Like most members of the Arf family, Arl1 is myristoylated at its N-terminal helix and mutation of the myristoylation site disrupts Golgi targeting. In humans, the Golgi-localized proteins golgin-97 and golgin-245 have been identified as Arl1 effectors. Golgins are large coiled-coil proteins found in the Golgi, and these golgins contain a C-terminal GRIP domain, which is the site of Arl1 binding. Additional Arl1 effectors include the GARP (Golgi-associated retrograde protein)/VFT (Vps53) vesicle-tethering complex and Arfaptin 2. Arl1 is not required for exocytosis, but appears necessary for trafficking from the endosomes to the Golgi. In Drosophila zygotes, mutation of Arl1 is lethal, and in the host-bloodstream form of Trypanosoma brucei, Arl1 is essential for viability.

186-276 2.46e-05

Arf-like tumor suppressor gene 1 (ARLTS1 or Arl11); ARLTS1 (Arf-like tumor suppressor gene 1), also known as Arl11, is a member of the Arf family of small GTPases that is believed to play a major role in apoptotic signaling. ARLTS1 is widely expressed and functions as a tumor suppressor gene in several human cancers. ARLTS1 is a low-penetrance suppressor that accounts for a small percentage of familial melanoma or familial chronic lymphocytic leukemia (CLL). ARLTS1 inactivation seems to occur most frequently through biallelic down-regulation by hypermethylation of the promoter. In breast cancer, ARLTS1 alterations were typically a combination of a hypomorphic polymorphism plus loss of heterozygosity. In a case of thyroid adenoma, ARLTS1 alterations were polymorphism plus promoter hypermethylation. The nonsense polymorphism Trp149Stop occurs with significantly greater frequency in familial cancer cases than in sporadic cancer cases, and the Cys148Arg polymorphism is associated with an increase in high-risk familial breast cancer.

Arf-like 6 (Arl6) GTPase; Arl6 (Arf-like 6) forms a subfamily of the Arf family of small GTPases. Arl6 expression is limited to the brain and kidney in adult mice, but it is expressed in the neural plate and somites during embryogenesis, suggesting a possible role for Arl6 in early development. Arl6 is also believed to have a role in cilia or flagella function. Several proteins have been identified that bind Arl6, including Arl6 interacting protein (Arl6ip), and SEC61beta, a subunit of the heterotrimeric conducting channel SEC61p. Based on Arl6 binding to these effectors, Arl6 is also proposed to play a role in protein transport, membrane trafficking, or cell signaling during hematopoietic maturation. At least three specific homozygous Arl6 mutations in humans have been found to cause Bardet-Biedl syndrome, a disorder characterized by obesity, retinopathy, polydactyly, renal and cardiac malformations, learning disabilities, and hypogenitalism. Older literature suggests that Arl6 is a part of the Arl4/Arl7 subfamily, but analyses based on more recent sequence data place Arl6 in its own subfamily.

172-276 4.49e-05

(ADP-ribosylation factor domain protein 1 (ARD1); ARD1 (ADP-ribosylation factor domain protein 1) is an unusual member of the Arf family. In addition to the C-terminal Arf domain, ARD1 has an additional 46-kDa N-terminal domain that contains a RING finger domain, two predicted B-Boxes, and a coiled-coil protein interaction motif. This domain belongs to the TRIM (tripartite motif) or RBCC (RING, B-Box, coiled-coil) family. Like most Arfs, the ARD1 Arf domain lacks detectable GTPase activity. However, unlike most Arfs, the full-length ARD1 protein has significant GTPase activity due to the GAP (GTPase-activating protein) activity exhibited by the 46-kDa N-terminal domain. The GAP domain of ARD1 is specific for its own Arf domain and does not bind other Arfs. The rate of GDP dissociation from the ARD1 Arf domain is slowed by the adjacent 15 amino acids, which act as a GDI (GDP-dissociation inhibitor) domain. ARD1 is ubiquitously expressed in cells and localizes to the Golgi and to the lysosomal membrane. Two Tyr-based motifs in the Arf domain are responsible for Golgi localization, while the GAP domain controls lysosomal localization.

190-281 4.86e-05

Arf-like 2 (Arl2) GTPase; Arl2 (Arf-like 2) GTPases are members of the Arf family that bind GDP and GTP with very low affinity. Unlike most Arf family proteins, Arl2 is not myristoylated at its N-terminal helix. The protein PDE-delta, first identified in photoreceptor rod cells, binds specifically to Arl2 and is structurally very similar to RhoGDI. Despite the high structural similarity between Arl2 and Rho proteins and between PDE-delta and RhoGDI, the interactions between the GTPases and their effectors are very different. In its GTP bound form, Arl2 interacts with the protein Binder of Arl2 (BART), and the complex is believed to play a role in mitochondrial adenine nucleotide transport. In its GDP bound form, Arl2 interacts with tubulin- folding Cofactor D; this interaction is believed to play a role in regulation of microtubule dynamics that impact the cytoskeleton, cell division, and cytokinesis.

Arf-like 5 (Arl5) and 8 (Arl8) GTPases; Arl5/Arl8 subfamily. Arl5 (Arf-like 5) and Arl8, like Arl4 and Arl7, are localized to the nucleus and nucleolus. Arl5 is developmentally regulated during embryogenesis in mice. Human Arl5 interacts with the heterochromatin protein 1-alpha (HP1alpha), a nonhistone chromosomal protein that is associated with heterochromatin and telomeres, and prevents telomere fusion. Arl5 may also play a role in embryonic nuclear dynamics and/or signaling cascades. Arl8 was identified from a fetal cartilage cDNA library. It is found in brain, heart, lung, cartilage, and kidney. No function has been assigned for Arl8 to date.

195-274 3.77e-04

Arf-related protein 1 (Arfrp1); Arfrp1 (Arf-related protein 1), formerly known as ARP, is a membrane-associated Arf family member that lacks the N-terminal myristoylation motif. Arfrp1 is mainly associated with the trans-Golgi compartment and the trans-Golgi network, where it regulates the targeting of Arl1 and the GRIP domain-containing proteins, golgin-97 and golgin-245, onto Golgi membranes. It is also involved in the anterograde transport of the vesicular stomatitis virus G protein from the Golgi to the plasma membrane, and in the retrograde transport of TGN38 and Shiga toxin from endosomes to the trans-Golgi network. Arfrp1 also inhibits Arf/Sec7-dependent activation of phospholipase D. Deletion of Arfrp1 in mice causes embryonic lethality at the gastrulation stage and apoptosis of mesodermal cells, indicating its importance in development.

Sar1 is an essential component of COPII vesicle coats; Sar1 is an essential component of COPII vesicle coats involved in export of cargo from the ER. The GTPase activity of Sar1 functions as a molecular switch to control protein-protein and protein-lipid interactions that direct vesicle budding from the ER. Activation of the GDP to the GTP-bound form of Sar1 involves the membrane-associated guanine nucleotide exchange factor (GEF) Sec12. Sar1 is unlike all Ras superfamily GTPases that use either myristoyl or prenyl groups to direct membrane association and function, in that Sar1 lacks such modification. Instead, Sar1 contains a unique nine-amino-acid N-terminal extension. This extension contains an evolutionarily conserved cluster of bulky hydrophobic amino acids, referred to as the Sar1-N-terminal activation recruitment (STAR) motif. The STAR motif mediates the recruitment of Sar1 to ER membranes and facilitates its interaction with mammalian Sec12 GEF leading to activation.

190-274 1.81e-03

Arf-like 3 (Arl3) GTPase; Arl3 (Arf-like 3) is an Arf family protein that differs from most Arf family members in the N-terminal extension. In is inactive, GDP-bound form, the N-terminal extension forms an elongated loop that is hydrophobically anchored into the membrane surface; however, it has been proposed that this region might form a helix in the GTP-bound form. The delta subunit of the rod-specific cyclic GMP phosphodiesterase type 6 (PDEdelta) is an Arl3 effector. Arl3 binds microtubules in a regulated manner to alter specific aspects of cytokinesis via interactions with retinitis pigmentosa 2 (RP2). It has been proposed that RP2 functions in concert with Arl3 to link the cell membrane and the cytoskeleton in photoreceptors as part of the cell signaling or vesicular transport machinery. In mice, the absence of Arl3 is associated with abnormal epithelial cell proliferation and cyst formation.
