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.

3-57 1.44e-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.

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.

3-57 1.44e-04

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.

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.

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.
