 260-408 1.34e-37

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

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

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.

VWA_collagen alpha 3(VI) like: 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.

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.

 260-371 5.95e-18

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.

 39-201 7.54e-17

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.

 260-401 1.26e-15

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.

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.

 40-188 8.69e-12

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.

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.

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.

 260-406 2.00e-05

Complement factors B and C2 are two critical proteases for complement activation. They both contain three CCP or Sushi domains, a trypsin-type serine protease domain and a single VWA domain with a conserved metal ion dependent adhesion site referred commonly as the MIDAS motif. Orthologues of these molecules are found from echinoderms to chordates. During complement activation, the CCP domains are cleaved off, resulting in the formation of an active protease that cleaves and activates complement C3. Complement C2 is in the classical pathway and complement B is in the alternative pathway. The interaction of C2 with C4 and of factor B with C3b are both dependent on Mg2+ binding sites within the VWA domains and the VWA domain of factor B has been shown to mediate the binding of C3. This is consistent with the common inferred function of VWA domains as magnesium-dependent protein interaction domains.

 261-383 1.69e-04

CTRP for CS protein-TRAP-related protein: Adhesion of Plasmodium to host cells is an important phenomenon in parasite invasion and in malaria associated pathology.CTRP encodes a protein containing a putative signal sequence followed by a long extracellular region of 1990 amino acids, a transmembrane domain, and a short cytoplasmic segment. The extracellular region of CTRP contains two separated adhesive domains. The first domain contains six 210-amino acid-long homologous VWA domain repeats. The second domain contains seven repeats of 87-60 amino acids in length, which share similarities with the thrombospondin type 1 domain found in a variety of adhesive molecules. Finally, CTRP also contains consensus motifs found in the superfamily of haematopoietin receptors. The VWA domains in these proteins likely mediate protein-protein interactions.

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.

 260-406 3.76e-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.
