TNF superfamily member 15 (TNFSF15), a cytokine largely produced by vascular endothelial cells and a specific inhibitor of the proliferation of these same cells, can inhibit VEGF-induced vascular permeability in vitro and in vivo, and that death receptor 3 (DR3), a cell surface receptor of TNFSF15, mediates TNFSF15-induced dephosphorylation of VEGFR2. TNFSF15 Protein, Cynomolgus Rhesus macaque, Recombinant (His) is expressed in HEK293 mammalian cells with N-His tag. The predicted molecular weight is 21.52 kDa and the accession number is A0A2K5UA22.
