Summary: (from NCBI-Entrez) ..[read more]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 li
ICAM-4 is a red cell intercellular adhesion molecule. Cell transfectants expressing various integrins were used to demonstrate that integrins alpha-L-beta-2, alpha-M-beta-2, and alpha-IIb-beta-3 bind specifically and dose dependently to the recombinant ICAM-4-Fc protein. Cell surface ICAM-4 interacts with the cell surface alpha-V-beta-3 integrin (Hermand et al. 2004).
Substrate specificity of alpha(v)beta(3) integrin-mediated cell migration and phosphatidylinositol 3-kinase/AKT pathway activation. Zheng DQ et al. The alpha(v)beta(3) integrin has been shown to bind several ligands, including osteopontin and vitronectin. Its role in modulating cell migration and downstream signaling pathways in response to specific extracellular matrix ligands has been investigated in this study. ... . We conclude therefore that alpha(v)beta(3) exists in multiple functional states that can bind either selectively vitronectin or both vitronectin and osteopontin and that can differentially activate cell migration and intracellular signaling pathways in a ligand-specific manner.
