| Post Translational Modifications | N- and O-glycosylated. Phosphorylated on Tyr-628 and Tyr-644 by SRC.these phosphorylations promote endothelial cell adhesion and migration. |
| Function | Cell surface receptor that plays a role in various physiological processes including inflammation, phagocytosis, and cell adhesion. Plays a role in phagocytosis and enhances the uptake of apoptotic cells and immune complexes by acting as a receptor for defense collagens including surfactant protein A/SFTPA1, C1q, and mannose-binding lectin (MBL2). Plays a role in the regulation of endothelial cell function and adhesion by activating angiogenesis. Mechanistically, exerts its angiogenic function by associating with beta-dystroglycan, leading to SRC-dependent phosphorylation and subsequent recruitment of CBL. In turn, CBL provides a docking site for downstream signaling components, such as CRKL to enhance cell migration. Participates in angiogenesis also by acting as a receptor for the ECM pan-endothelial glycoprotein multimerin-2/MMRN2 and IGFBP7 ligands. Both ligands play a non-redundant role in CD93-mediated endothelial cell function. Acts as a key regulator of endothelial barrier function through modulating VEGFR2 function. |
