Angiopoietin-2, also known as ANGPT2, belongs to a family of vascular growth factors. It plays essential roles in embryonic and postnatal angiogenesis. The structure of the mature form of Angiopoietin-2 contains an N-terminal coiled-coil domain, which mediates multimerization of the protein, along with a C-terminal fibrinogen-like domain, which mediates the receptor binding. Both Angiopoietin-1 and Angiopoietin-2 are ligands for the receptor tyrosine kinase, Tie-2. Angiopoietin-2 appears to exist predominantly as a homodimer, but it is also capable of forming multimers while Angiopoietin-1 predominantly exists as multimers. It has been shown that Angiopoietin-2 is able to promote vascular leakage and neutrophil migration. It can also sensitize TNF-α-induced monocyte adhesion. Thus, it is considered a proinflammatory factor. Although Angiopoietin-2 is not required for arterial vascular development, its expression in the tissue suggests that it may play a role in the maintenance of these vessels. This conclusion is also supported by the observation that high concentrations of Angiopoietin-2 activate the same survival signaling pathway as Angiopoietin-1 to prevent endothelial cell apoptosis via Tie-2/Akt. Additionally, Angiopoietin-2 functions as an agonist in the absence of Angiopoietin-1, but it acts as an antagonist in its presence. Human Angiopoietin-2 shares an 86% amino acid sequence homology with its murine counterpart.Product Details
