VEGFR-2 protein is a tyrosine protein kinase receptor for VEGFA, VEGFC and VEGFD and is critical in angiogenesis, blood vessel development and embryonic hematopoiesis. It promotes endothelial cell function and actin cytoskeletal reorganization. VEGFR-2 Protein, Human (745a.a, HEK293, Fc) is the recombinant human-derived VEGFR-2 protein, expressed by HEK293 , with C-hFc labeled tag.

Human

VEGFR-2 protein, a tyrosine-protein kinase, serves as a cell-surface receptor for VEGFA, VEGFC, and VEGFD, playing a pivotal role in the intricate regulation of angiogenesis, vascular development, vascular permeability, and embryonic hematopoiesis. It actively promotes the proliferation, survival, migration, and differentiation of endothelial cells, while also influencing the reorganization of the actin cytoskeleton. Certain isoforms, lacking a transmembrane domain like isoform 2 and isoform 3, may function as decoy receptors, modulating VEGFA, VEGFC, and/or VEGFD signaling. Specifically, isoform 2 acts as a negative regulator of VEGFA- and VEGFC-mediated lymphangiogenesis by limiting the availability of free VEGFA and/or VEGFC, preventing their binding to FLT4. VEGFR-2 modulates FLT1 and FLT4 signaling through heterodimer formation. Binding of vascular growth factors to isoform 1 triggers multiple signaling cascades, including the activation of PLCG1, resulting in the production of diacylglycerol and inositol 1,4,5-trisphosphate and the subsequent activation of protein kinase C. Additionally, VEGFR-2 mediates the activation of MAP kinase signaling pathways, AKT1 signaling pathway, and the phosphorylation of PIK3R1, contributing to the reorganization of the actin cytoskeleton and the activation of PTK2/FAK1. Its crucial role extends to facilitating VEGFA-mediated induction of NOS2 and NOS3, leading to the production of the signaling molecule nitric oxide (NO) by endothelial cells. VEGFR-2's phosphorylation activity includes PLCG1, FYN, NCK1, NOS3, PIK3R1, PTK2/FAK1, and SRC, highlighting its comprehensive involvement in modulating diverse cellular processes.
