Integrin α-V (CD51) is a surface protein from the group of integrins .

properties

Integrin α-V is a cell adhesion molecule and binds to the RGD sequence as well as vitronectin , cytotactin , fibronectin , fibrinogen , laminin , matrix metalloproteinase-2 , osteopontin , osteomodulin , prothrombin , thrombospondin and the von Willebrand factor . It's glycosylated . Integrin α-V forms a heterodimeric receptor with integrin beta-3 for fractalkin , FGF-1 , IGF-1 , and NRG1 . Furthermore, it binds PLA2G2A at a different binding site, which increases the affinity for binding other ligands . The receptor consisting of integrin alpha-V and integrin beta-3 as well as the complex consisting of integrin alpha-V and integrin beta-6 bind fibrillin-1 and are thus involved in cell adhesion .

The adenovirus of type C used the complex of the integrin α-V and integrin beta-5 as a receptor. Coxsackieviruses of types A9 and B1 use the complex of integrin α-V and either integrin beta-3 or integrin beta-5 as a receptor. The HHV-8 , the West Nile virus and the human Parechovirus 1 using the complex of the integrin α-V and integrin beta-3 as the receptor.

The antibodies abituzumab and intetumumab bind to integrin α-V.
