UniProtKB/Swiss-Prot PTM Description

Endostatin: Potently inhibits endothelial cell proliferation and angiogenesis (PubMed:9459295). May inhibit angiogenesis by binding to the heparan sulfate proteoglycans involved in growth factor signaling (By similarity). Inhibits VEGFA-induced endothelial cell proliferation and migration. Seems to inhibit VEGFA-mediated signaling by blocking the interaction of VEGFA to its receptor KDR/VEGFR2. Modulates endothelial cell migration in an integrin-dependent manner implicating integrin ITGA5:ITGB1 and to a lesser extent ITGAV:ITGB3 and ITGAV:ITGB5 (By similarity). May negatively regulate the activity of homotrimeric non-collagenous domain 1 (PubMed:11257123)

Prolines at the third position of the tripeptide repeating unit (G-X-Y) of the triple-helical regions are hydroxylated Circulating endostatins are found as sialoglycoprotein and asialoglycoprotein structures Undergoes proteolytic processing by cathepsin-L and elastase-like proteases to generate both NC1 trimers and endostatin monomers (PubMed:10626789). In vitro, several proteolytic cleavage sites in the non-collagenous domain 1 hinge region generating different endostatin-like peptides are reported
