background:
Integrins are heterodimeric proteins made up of alpha and beta subunits. At least 18 alpha and 8 beta subunits have been described in mammals. Integrin family members are membrane receptors involved in cell adhesion and recognition in a variety of processes including embryogenesis, hemostasis, tissue repair, immune response and metatastatic diffusion of tumour cells. 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.

整合素αVβ3、αVβ5是特异性表达在血管内皮细胞表面的粘附因子，在介导内皮细胞和ECM相互接触中起作用。
整合素（integrin）分布广泛，属于细胞黏附分子家族。经研究发现整合素可以调节细胞-细胞、细胞-细胞外基质(extracellular matrix，ECM〕间的黏附。整合素所介导的肿瘤细胞与ECM间的相互作用影响肿瘤的发生、增殖、侵袭和转移到其他组织的能力。
