The C-type lectin domain is required for binding to integrins (PubMed:37184585). Binding to soluble integrins alpha-V/beta-3 (ITGAV:ITGB3) and alpha-IIb/beta3 (ITGA2B:ITGB) is cation-dependent in order of preference of 1 mM Mn(2+) > Mg(2+) > Ca(2+) (PubMed:37184585). Binds to the allosteric site (site 2) of integrins and activates them (PubMed:37184585). The interaction with integrins may mediate cell-cell interactions and cell adhesion (PubMed:37184585).

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).

Belongs to the selectin/LECAM family.

Stored in the alpha-granules of platelets and Weibel-Palade bodies of endothelial cells. Upon cell activation by agonists, P-selectin is transported rapidly to the cell surface.
