The function of ENSG00000174175 (SELP, selectin P) is as follows. Ca(2+)-dependent receptor for myeloid cells that binds to carbohydrates on neutrophils and monocytes. Mediates the interaction of activated endothelial cells or platelets with leukocytes. The ligand recognized is sialyl-Lewis X. Mediates rapid rolling of leukocyte rolling over vascular surfaces during the initial steps in inflammation through interaction with SELPLG. Mediates cell-cell interactions and cell adhesion via the interaction with integrin alpha-IIb/beta3 (ITGA2B:ITGB3) and integrin alpha-V/beta-3 (ITGAV:ITGB3) (PubMed:37184585). {ECO:0000269|PubMed:11081633, ECO:0000269|PubMed:28011641, ECO:0000269|PubMed:37184585, ECO:0000269|PubMed:7585950}.
