ANGPT2 aka Angiopoietin-2 competes for binding to the TIE2 receptor and blocks angiopoietin-1 aka ANGPT1 induced TIE2 autophosphorylation during vasculogenesis. ANGPT-2 is a naturally occurring antagonist of ANGPT-1. ANGPT2 induces tyrosine phosphorylation of TEK/TIE2 in the lack of Angiopoietin-2. In the deficiency of VEGF an angiogenic inducer, ANGPT-2 induces endothelial cell apoptosis resulting in vascular regression. ANGPT2 along with VEGF enable endothelial cell migration and proliferation, resulting in permissive angiogenic signal.

ANGPT2 produced in Chinese hamster ovary (CHO) cells by recombinant DNA technology is a single, polypeptide chain (19-496 a.a.) and fused to a 6 aa His Tag at C-terminus containing a total of 484 amino acids and having a molecular mass of 55.7kDa.ANGPT2 shows multiple bands between 50-100kDa on SDS-PAGE, reducing conditions and purified by proprietary chromatographic techniques.

UniProt Protein Function:ANGPT2: Binds to TEK/TIE2, competing for the ANGPT1 binding site, and modulating ANGPT1 signaling. Can induce tyrosine phosphorylation of TEK/TIE2 in the absence of ANGPT1. In the absence of angiogenic inducers, such as VEGF, ANGPT2-mediated loosening of cell-matrix contacts may induce endothelial cell apoptosis with consequent vascular regression. In concert with VEGF, it may facilitate endothelial cell migration and proliferation, thus serving as a permissive angiogenic signal. Interacts with TEK/TIE2, competing for the same binding site as ANGPT1. 3 isoforms of the human protein are produced by alternative splicing.

NCBI Summary:The protein encoded by this gene is an antagonist of angiopoietin 1 (ANGPT1) and endothelial TEK tyrosine kinase (TIE-2, TEK). The encoded protein disrupts the vascular remodeling ability of ANGPT1 and may induce endothelial cell apoptosis. Three transcript variants encoding three different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
