Background: Integrin alpha V beta 3

Integrin alpha V beta 3 together with alpha IIb beta 3, constitutes the only known beta 3 Integrins (13). The noncovalent heterodimer of 170 kDa alpha V/CD51 and 93 kDa beta 3/CD61 subunits shows wide expression, notably by endothelial cells and osteoclasts (24). Each subunit has a transmembrane sequence and a short cytoplasmic tail connected to the cytoskeleton. Active cell surface alpha V beta 3 adheres to matrix proteins including vitronectin, fibronectin, fibrinogen and thrombospondin (2, 3). The ligand binding site of alpha V beta 3 is in the Nterminal head region, formed by interaction of the beta 3 vWFA domain with the alpha V betapropeller structure (4). The alpha V subunit contributes a "thigh and a calf" region, while the beta 3 subunit contains a PSI domain and four cysteinerich IEGF folds. The alpha V subunit domains termed thigh, calf1 and calf2 generate a "knee" region that is bent when the alpha V beta 3 is in its constitutively inactive state. Activation, either by "inside out" signaling or by Mg2+ or Mn2+ binding, extends the Integrin to expose its ligand binding site (1, 4). Within the extracellular domain (ECD), cynomolgus alpha V shares 99% amino acid (aa) sequence identity with the 962 aa human alpha V, while cynomolgus beta 3 ECD shares almost 100% aa sequence identity with the 692 aa human beta 3 ECD. Two splice variants of beta 3 (b and c) diverge over the last 21 amino acids (aa) and lack cytoplasmic phosphorylation sites (5, 6). Another beta 3 splice variant diverges after the vWFA domain, producing a soluble 60 kDa form in platelets and endothelial cells (7). alpha V beta 3 is essential for the maturation of osteoclasts and their binding and resorption of bone, as well as promotes their apoptosis (8, 9). MCSF R and alpha V beta 3 share signaling pathways during osteoclastogenesis, and deletion of either molecule causes osteopetrosis (8, 9). Cell entry of several viruses is mediated by alpha V beta 3 (4, 10). alpha V beta 3 is involved in several other signaling pathways by direct interaction with receptor tyrosine kinases and ligands. For example, it cooperates with endothelial cell VEGF R2 in angiogenesis, and with IGF1 to promote cancer cell proliferation and invasiveness (11, 12).
