Description
Product Characteristics: CD51 represents the 150 kDa integrin V chain that associates with integrin 3 (CD61) to form the CD51/CD61 vitronectin receptor on endothelial cells, certain activated leukocytes, NK cells, macrophages, neutrophils and platelets. CD51 is the most promiscuous integrin a subunit, it can form heterodimers with the 1 (CD29), 3 (CD61), 5, 6 and 8 subunits in various tissues. CD51/CD61 acts as an activation-independent receptor for platelet attachment and spreading on vitronectin and other RGD-containing proteins, including matrix components. It also mediates leukocyte-endothelial cell adhesion via interaction with CD31.
Target Information: ITAGV encodes integrin alpha chain V. Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. The I-domain containing integrin alpha V undergoes post-translational cleavage to yield disulfide-linked heavy and light chains, that combine with multiple integrin beta chains to form different integrins. Among the known associating beta chains (beta chains 1,3,5,6, and 8\, 'ITGB1', 'ITGB3', 'ITGB5', 'ITGB6', and 'ITGB8'), each can interact with extracellular matrix ligands\, the alpha V beta 3 integrin, perhaps the most studied of these, is referred to as the Vitronectin receptor (VNR). In addition to adhesion, many integrins are known to facilitate signal transduction. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2009]
