 1-144 3.48e-79

Von Willebrand factor type A (vWA) domain was originally found in the blood coagulation protein von Willebrand factor (vWF). Typically, the vWA domain is made up of approximately 200 amino acid residues folded into a classic a/b para-rossmann type of fold. The vWA domain, since its discovery, has drawn great interest because of its widespread occurrence and its involvement in a wide variety of important cellular functions. These include basal membrane formation, cell migration, cell differentiation, adhesion, haemostasis, signaling, chromosomal stability, malignant transformation and in immune defenses In integrins these domains form heterodimers while in vWF it forms multimers. There are different interaction surfaces of this domain as seen by the various molecules it complexes with. Ligand binding in most cases is mediated by the presence of a metal ion dependent adhesion site termed as the MIDAS motif that is a characteristic feature of most, if not all A domains.

 1-144 3.48e-79

ATR (Anthrax Toxin Receptor): Anthrax toxin is a key virulence factor for Bacillus anthracis, the causative agent of anthrax. ATR is the cellular receptor for the anthrax protective antigen and facilitates entry of the toxin into cells. The VWA domain in ATR contains the toxin binding site and mediates interaction with protective antigen. The binding is mediated by divalent cations that binds to the MIDAS motif. These proteins are a family of vertebrate ECM receptors expressed by endothelial cells.

Von Willebrand factor type A (vWA) domain was originally found in the blood coagulation protein von Willebrand factor (vWF). Typically, the vWA domain is made up of approximately 200 amino acid residues folded into a classic a/b para-rossmann type of fold. The vWA domain, since its discovery, has drawn great interest because of its widespread occurrence and its involvement in a wide variety of important cellular functions. These include basal membrane formation, cell migration, cell differentiation, adhesion, haemostasis, signaling, chromosomal stability, malignant transformation and in immune defenses In integrins these domains form heterodimers while in vWF it forms multimers. There are different interaction surfaces of this domain as seen by the various molecules it complexes with. Ligand binding in most cases is mediated by the presence of a metal ion dependent adhesion site termed as the MIDAS motif that is a characteristic feature of most, if not all A domains.

Not much is known about the function of the VWA domain in these proteins. The members do have a conserved MIDAS motif. The biochemical function however is not known.

VWA_collagen alpha(VI) type: The extracellular matrix represents a complex alloy of variable members of diverse protein families defining structural integrity and various physiological functions. The most abundant family is the collagens with more than 20 different collagen types identified thus far. Collagens are centrally involved in the formation of fibrillar and microfibrillar networks of the extracellular matrix, basement membranes as well as other structures of the extracellular matrix. Some collagens have about 15-18 vWA domains in them. The VWA domains present in these collagens mediate protein-protein interactions.

 2-122 1.36e-03

von Willebrand factor (vWF) type A domain; equivalent to the I-domain of integrins. This domain has a variety of functions including: intermolecular adhesion, cell migration, signalling, transcription, and DNA repair. In integrins these domains form heterodimers while in vWF it forms homodimers and multimers. There are different interaction surfaces of this domain as seen by its complexes with collagen with either integrin or human vWFA. In integrins collagen binding occurs via the metal ion-dependent adhesion site (MIDAS) and involves three surface loops located on the upper surface of the molecule. In human vWFA, collagen binding is thought to occur on the bottom of the molecule and does not involve the vestigial MIDAS motif.

Micronemal proteins: The Toxoplasma lytic cycle begins when the parasite actively invades a target cell. In association with invasion, T. gondii sequentially discharges three sets of secretory organelles beginning with the micronemes, which contain adhesive proteins involved in parasite attachment to a host cell. Deployed as protein complexes, several micronemal proteins possess vertebrate-derived adhesive sequences that function in binding receptors. The VWA domain likely mediates the protein-protein interactions of these with their interacting partners.
