Integrin alpha V/CD51 in Human Mesenchymal Stem Cells. Integrin aV/CD51 was detected in immersion fixed human mesenchymal stem cells using Goat Anti-Human Integrin aV/CD51 Biotinylated Antigen Affinity-purified Polyclonal Antibody (Catalog # BAF1219) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Streptavidin (red; Catalog # NL999) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm and cell surface.

Background: Integrin alpha V/CD51

Integrin alpha V, also known as CD51 and vitronectin receptor subunit  alpha, is a 140 - 150 kDa integrin alpha chain that forms dimers with at least five beta chains including beta 1, 3, 5, 6, and 8. It is a 1018 amino acid (aa) residue type I membrane protein with a large (962 aa) extracellular domain (ECD) and a short (32 aa) cytoplasmic tail. The N-terminal region of alpha V, which is important for ligand binding, contains seven FG-GAP (phenylalanyl-glycyl and glycyl-alanyl-prolyl) concensus repeats that fold into a beta -propellar domain. Furin cleavage of the alpha V ECD occurs after Gly 889, generating a disulfide-linked, heteromeric subunit alpha V chain. alpha V-containing integrins bind multiple ECM molecules, including vitronectin, osteopontin, MMP-2, and TSP. The ECD of human Integrin  alpha V shares 92% aa sequence identity with mouse Integrin  alpha V ECD.
