Target description

Integrin alphaV beta8 (UniProt: P06756/ P26012; also known as Fibronectin receptor) are encoded by the ITGAV:ITGB8 genes (Gene ID: 3685/369) in human. Integrins are heterodimeric cell surface receptors composed of a variable alpha subunit and a conserved beta subunit. The exact combination of various alpha and beta subunits dictates the binding specificity of integrins to different ECM components. Integrins are not constitutively active. Activation of an integrin from low ligand-binding affinity state to high ligand-binding affinity state requires conformational change that can originate from either from their cytoplasmic or extracellular interactions. Integrin alphaV, a single-pass membrane protein, heterodimerizes with a beta subunit. The exact combination of various alpha and beta subunits dictates the binding specificity of integrins to different ECM components. Although both subunits are required for adhesion, the binding specificity primarily depends on the extracellular region of the alpha subunit. AlphaV associates with various beta subunits in a non-covalent manner. The structural and functional diversity of the integrin family are based upon the pairing abilities of the individual alpha and beta subunits. The alphaV is synthesized with a signal peptide (aa 1-30), which is subsequently cleaved off to generate the mature form. The mature form contains an extracellular domain (aa 31-992), a transmembrane domain (aa 993-1016), and a cytoplasmic domain (aa 1017-1048). Integrin beta8 is synthesized with a signal peptide (aa 1-42), which is cleaved off to produce the mature form that contains an extracellular domain (aa 43-684), a short transmembrane domain (aa 685-704), and a cytoplasmic domain (aa 705-769). Integrin alphaV beta8 (ITGAV:ITGB8) serves as a receptor for fibronectin. It recognizes the sequence R-G-D in its ligand. Clone EM13309 is shown to bind to alpha-V beta-8 with high affinity (EC50 = 10 ng/mL). It is shown to stain a subset of tumor cell lines, including ovarian carcinomas (Ovcar3; Igrov1; SKOV3) and some melanomas. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
