ITGAV/ITGB3 Antibodies

Target Information

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. The ITGB3 protein product is the integrin beta chain beta 3. Integrins are integral cell-surface proteins composed of an alpha chain and a beta chain. A given chain may combine with multiple partners resulting in different integrins. Integrin beta 3 is found along with the alpha IIb chain in platelets. Integrins are known to participate in cell adhesion as well as cell-surface mediated signaling.

CD61, also known as GPIIIa or ITGB3, is a 105 kDa glycoprotein expressed on activated T cells, granulocytes, megakaryocytes, platelets, and their precursors. It plays a crucial role in platelet aggregation and functions as a receptor for fibrinogen, fibronectin, von Willebrand factor, vitronectin, and thrombospondin. CD61 forms heterodimeric complexes by associating non-covalently with integrin alpha subunits: alphaV (CD51) to create the Vitronectin Receptor and alphaIIb (CD41) to form gpIIb/IIIa. These complexes are responsible for adhesion to extracellular matrix components, facilitating cell adhesion and cell-surface mediated signaling. CD61 is expressed on platelets and megakaryocytes in association with CD41, and on endothelial cells, monocytes, and osteoclasts in association with CD51. The protein product of CD61 is composed of an alpha chain and a beta chain, which can combine with multiple partners to form different integrins. Its involvement in cell adhesion and signaling underscores its importance in normal physiological processes. Dysfunction of CD61 is associated with diseases such as Glanzmann Thrombasthenia and Platelet type-16 Bleeding Disorder, highlighting its critical role in hemostasis and platelet function.
