Angiopoietin-2 Protein, Rat, Recombinant (E. coli, His)

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. Angiopoietin-2 Protein, Rat, Recombinant (E. coli, His) is expressed in E. coli expression system with N-6xHis tag. The predicted molecular weight is 58.6 kDa and the accession number is O35462.
