inter-alpha-trypsin inhibitor heavy chain H1 isoform c [Homo sapiens]

Protein Classification

inter-alpha-trypsin inhibitor heavy chain H; vWA domain-containing protein( domain architecture ID 10106957)

inter-alpha-trypsin inhibitor heavy chain H may act as a carrier of hyaluronan in serum or as a binding protein between hyaluronan and other matrix protein, including those on cell surfaces in tissues to regulate the localization, synthesis and degradation of hyaluronan which are essential to cells undergoing biological processes| vWA (von Willebrand factor type A) domain-containing protein may be involved in one of a wide variety of important cellular functions, including basal membrane formation, cell migration, cell differentiation, adhesion, haemostasis, signaling, chromosomal stability, malignant transformation and immune defenses

Inter-alpha-trypsin inhibitors are glycoproteins with a high inhibitory activity against trypsin, built up from different combinations of four polypeptides: bikunin and the three heavy chains that belong to this family (HC1, HC2, HC3). The heavy chains do not have any protease inhibitory properties but have the capacity to interact in vitro and in vivo with hyaluronic acid, which promotes the stability of the extra-cellular matrix. All family members contain the pfam00092 domain.

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.

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.

 4-165 1.03e-20

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.

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. Membes of this subgroup belong to Zinc-finger family as they are found fused to RING finger domains. The MIDAS motif is not conserved in all the members of this family. The function of vWA domains however is not known.

VWA Voltage gated Calcium channel like: Voltage-gated calcium channels are a complex of five proteins: alpha 1, beta 1, gamma, alpha 2 and delta. The alpha 2 and delta subunits result from proteolytic processing of a single gene product and carries at its N-terminus the VWA and cache domains, The alpha 2 delta gene family has orthologues in D. melanogaster and C. elegans but none have been detected in aither A. thaliana or yeast. The exact biochemical function of the VWA domain is not known but the alpha 2 delta complex has been shown to regulate various functional properties of the channel complex.

 4-131 1.26e-04

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

Magnesium chelatase: Mg-chelatase catalyses the insertion of Mg into protoporphyrin IX (Proto). In chlorophyll biosynthesis, insertion of Mg2+ into protoporphyrin IX is catalysed by magnesium chelatase in an ATP-dependent reaction. Magnesium chelatase is a three sub-unit (BchI, BchD and BchH) enzyme with a novel arrangement of domains: the C-terminal helical domain is located behind the nucleotide binding site. The BchD domain contains a AAA domain at its N-terminus and a VWA domain at its C-terminus. The VWA domain has been speculated to be involved in mediating protein-protein interactions.

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.
