Angiopoietin-2 (ANGPT2) protein competes with ANGPT1 for TEK/TIE2 binding, modulates ANGPT1 signaling and induces TEK/TIE2 phosphorylation even in the absence of ANGPT1. In the absence of angiogenic stimulation, ANGPT2 disrupts cell-matrix contacts, potentially triggering endothelial cell apoptosis and vessel regression. Angiopoietin-2 Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived Angiopoietin-2 protein, expressed by HEK293 , with N-His, N-Avi labeled tag. The total length of Angiopoietin-2 Protein, Human (Biotinylated, HEK293, His-Avi) is 222 a.a., with molecular weight of 32-37 kDa.

Human

The Angiopoietin-2 (ANGPT2) protein binds to TEK/TIE2, competing for the ANGPT1 binding site and thereby modulating ANGPT1 signaling. This interaction can induce the tyrosine phosphorylation of TEK/TIE2 even in the absence of ANGPT1. In the absence of angiogenic inducers, such as VEGF, ANGPT2's action leads to the loosening of cell-matrix contacts, potentially inducing endothelial cell apoptosis and consequent vascular regression. However, in the presence of VEGF, ANGPT2 collaborates to facilitate endothelial cell migration and proliferation, acting as a permissive angiogenic signal. Furthermore, ANGPT2 is involved in the regulation of lymphangiogenesis. The protein also interacts with TEK/TIE2, competing for the same binding site as ANGPT1, and additionally interacts with ITGA5, contributing to its multifaceted role in angiogenesis and vascular regulation.
