General description
Angiopoietin-2 (UniProt: O15123; also known as ANG-2) is encoded by the ANGPT2 gene (Gene ID: 285) in human. Angiopoietins are a family of growth factors that include Angiopoietin 1 and 2 and the orthologs 3 (in mouse) and 4 (in human). ANG-2 is a secreted glycoprotein that is expressed predominantly by endothelial cells and some smooth muscle cells in a tightly regulated manner. High expression of ANG-2 has been observed in placenta. In quiescent mature vessels its expression is shown to be low; however, upon receipt of inflammatory signals its levels are significantly elevated. ANG-2 binds to TEK/TIE2 and competes for the Angiopoietin-1 (ANG-1) binding site and modulates ANG-1 signaling. It is also reported to induce tyrosine phosphorylation of TEK/TIE2 in the absence of ANG-1. Both ANG-1 and ANG-2 have been implicated in tumor angiogenesis and ANG-2 is highly up-regulated in the vasculature of mouse and human neoplasms. It also acts as a chemoattractant and mediates the migration of a monocytes that express Tie2 receptor. ANG-2 contains a fibrinogen C-terminal domain (aa 275-495) that mediates its interaction with the TEK/TIE2 receptor. Three isoforms of ANG-2 have been described that are produced by alternative splicing. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
