Calcium-dependent lectin that mediates cell adhesion by binding to glycoproteins on neighboring cells (PubMed:12403782, PubMed:28489325, PubMed:28011641). Mediates the adherence of lymphocytes to endothelial cells of high endothelial venules in peripheral lymph nodes. Promotes initial tethering and rolling of leukocytes in endothelia (PubMed:12403782, PubMed:28011641).
The C5a receptor mediates the pro-inflammatory and chemotactic actions of the complement anaphylatoxin C5a. In addition to stimulating chemotaxis, granule enzyme release and superoxide anion production, this receptor stimulates upregulation of expression and activity of the adhesion molecule MAC-1, and of CR1, and a decrease in cell-surface glycoprotein 100MEL-14 on neutrophils.
