Angpt2 (Angiopoietin-2, ANG-2, Agpt2)

Angiopoietin2 (Ang2?also ANGPT2) is a secreted 66-70kD glycoprotein member of the angiopoietin family of growth factors. It is expressed by endothelial cells, macrophages and skeletal muscle fibers, and binds to the Tie2 receptor on select cell types, including endothelial cells and monocytes. Ang2 has multiple functions. In the presence of growth factors, it promotes angiogenesis? in the absence of growth factors, it induces vascular regression. It is generally considered to be an antagonist of Ang1activity. Mature mouse Ang2 is 478aa in length (aa19-496). It contains one coiled coil region (aa159-256) plus a C-terminal Fibrinogen like domain (aa275-495). Mouse Ang2 undergoes covalent oligomerization, forming 140kD homodimers and 280kD homotetramers. The higher order oligomers are strong Tie2 agonists. Over aa68-496, mouse Ang2 shares 87% and 96% aa sequence identity with human and rat Ang2, respectively.\n\nApplications:\nSuitable for use in Western Blot.
