 149-324 9.72e-92

Integrins are a class of adhesion receptors that link the extracellular matrix to the cytoskeleton and cooperate with growth factor receptors to promote celll survival, cell cycle progression and cell migration. Integrins consist of an alpha and a beta sub-unit. Each sub-unit has a large extracellular portion, a single transmembrane segment and a short cytoplasmic domain. The N-terminal domains of the alpha and beta subunits associate to form the integrin headpiece, which contains the ligand binding site, whereas the C-terminal segments traverse the plasma membrane and mediate interaction with the cytoskeleton and with signalling proteins.The VWA domains present in the alpha subunits of integrins seem to be a chordate specific radiation of the gene family being found only in vertebrates. They mediate protein-protein interactions.

Integrin alpha (beta-propellor repeats); Integrins are cell adhesion molecules that mediate cell-extracellular matrix and cell-cell interactions. They contain both alpha and beta subunits. Alpha integrins are proposed to contain a domain containing a 7-fold repeat that adopts a beta-propellor fold. Some of these domains contain an inserted von Willebrand factor type-A domain. Some repeats contain putative calcium-binding sites. The 7-fold repeat domain is homologous to a similar domain in phosphatidylinositol-glycan-specific phospholipase D.

von Willebrand factor (vWF) type A domain; VWA domains in extracellular eukaryotic proteins mediate adhesion via metal ion-dependent adhesion sites (MIDAS). Intracellular VWA domains and homologues in prokaryotes have recently been identified. The proposed VWA domains in integrin beta subunits have recently been substantiated using sequence-based methods.

Integrin alpha (beta-propellor repeats); Integrins are cell adhesion molecules that mediate cell-extracellular matrix and cell-cell interactions. They contain both alpha and beta subunits. Alpha integrins are proposed to contain a domain containing a 7-fold repeat that adopts a beta-propellor fold. Some of these domains contain an inserted von Willebrand factor type-A domain. Some repeats contain putative calcium-binding sites. The 7-fold repeat domain is homologous to a similar domain in phosphatidylinositol-glycan-specific phospholipase D.

FG-GAP repeat; This family contains the extracellular repeat that is found in up to seven copies in alpha integrins. This repeat has been predicted to fold into a beta propeller structure. The repeat is called the FG-GAP repeat after two conserved motifs in the repeat. The FG-GAP repeats are found in the N terminus of integrin alpha chains, a region that has been shown to be important for ligand binding. A putative Ca2+ binding motif is found in some of the repeats.

 149-324 9.72e-92

Integrins are a class of adhesion receptors that link the extracellular matrix to the cytoskeleton and cooperate with growth factor receptors to promote celll survival, cell cycle progression and cell migration. Integrins consist of an alpha and a beta sub-unit. Each sub-unit has a large extracellular portion, a single transmembrane segment and a short cytoplasmic domain. The N-terminal domains of the alpha and beta subunits associate to form the integrin headpiece, which contains the ligand binding site, whereas the C-terminal segments traverse the plasma membrane and mediate interaction with the cytoskeleton and with signalling proteins.The VWA domains present in the alpha subunits of integrins seem to be a chordate specific radiation of the gene family being found only in vertebrates. They mediate protein-protein interactions.

 149-313 2.22e-31

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

Collagen: 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.

 150-318 2.92e-27

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.

 150-313 5.31e-26

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.

VWA_Matrilin: In cartilaginous plate, extracellular matrix molecules mediate cell-matrix and matrix-matrix interactions thereby providing tissue integrity. Some members of the matrilin family are expressed specifically in developing cartilage rudiments. The matrilin family consists of at least four members. All the members of the matrilin family contain VWA domains, EGF-like domains and a heptad repeat coiled-coiled domain at the carboxy terminus which is responsible for the oligomerization of the matrilins. The VWA domains have been shown to be essential for matrilin network formation by interacting with matrix ligands.

VWA_integrin (invertebrates): Integrins are a family of cell surface receptors that have diverse functions in cell-cell and cell-extracellular matrix interactions. Because of their involvement in many biologically important adhesion processes, integrins are conserved across a wide range of multicellular animals. Integrins from invertebrates have been identified from six phyla. There are no data to date to suggest any immunological functions for the invertebrate integrins. The members of this sub-group have the conserved MIDAS motif that is charateristic of this domain suggesting the involvement of the integrins in the recognition and binding of multi-ligands.

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.

Integrin alpha (beta-propellor repeats); Integrins are cell adhesion molecules that mediate cell-extracellular matrix and cell-cell interactions. They contain both alpha and beta subunits. Alpha integrins are proposed to contain a domain containing a 7-fold repeat that adopts a beta-propellor fold. Some of these domains contain an inserted von Willebrand factor type-A domain. Some repeats contain putative calcium-binding sites. The 7-fold repeat domain is homologous to a similar domain in phosphatidylinositol-glycan-specific phospholipase D.

Integrin alpha (beta-propellor repeats); Integrins are cell adhesion molecules that mediate cell-extracellular matrix and cell-cell interactions. They contain both alpha and beta subunits. Alpha integrins are proposed to contain a domain containing a 7-fold repeat that adopts a beta-propellor fold. Some of these domains contain an inserted von Willebrand factor type-A domain. Some repeats contain putative calcium-binding sites. The 7-fold repeat domain is homologous to a similar domain in phosphatidylinositol-glycan-specific phospholipase D.

 149-289 1.72e-06

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.

FG-GAP repeat; This family contains the extracellular repeat that is found in up to seven copies in alpha integrins. This repeat has been predicted to fold into a beta propeller structure. The repeat is called the FG-GAP repeat after two conserved motifs in the repeat. The FG-GAP repeats are found in the N terminus of integrin alpha chains, a region that has been shown to be important for ligand binding. A putative Ca2+ binding motif is found in some of the repeats.

 152-291 3.14e-03

VWA subgroup: 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.

 240-290 5.03e-03

norD type: Denitrifying bacteria contain both membrane bound and periplasmic nitrate reductases. Denitrification plays a major role in completing the nitrogen cycle by converting nitrate or nitrite to nitrogen gas. The pathway for microbial denitrification has been established as NO3- ------> NO2- ------> NO -------> N2O ---------> N2. This reaction generally occurs under oxygen limiting conditions. Genetic and biochemical studies have shown that the first srep of the biochemical pathway is catalyzed by periplasmic nitrate reductases. This family is widely present in proteobacteria and firmicutes. This version of the domain is also present in some archaeal members. The function of the vWA domain in this sub-group is not known. Members of this subgroup have a conserved MIDAS motif.
