Alternative NamesP-selectin; CD62 antigen-like family member P; Granule membrane protein 140; GMP-140; Leukocyte-endothelial cell adhesion molecule 3; LECAM3; Platelet activation dependent granule-external membrane protein; PADGEM; CD antigen CD62P

Function

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.

Biological Context

Subcellular Location: Cell membrane (Single-pass type I membrane protein)
Tissue Specificity: 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

Protein Biology

Function

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)

Subcellular Location

Cell membrane (Single-pass type I membrane protein)

Tissue Specificity

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

Subunit

Interacts with SNX17. Interacts with SELPLG/PSGL1 and PODXL2 and mediates neutrophil adhesion and leukocyte rolling. This interaction requires the sialyl-Lewis X epitope of SELPLG and PODXL2, and specific tyrosine sulfation on SELPLG. Interacts (via C-type lectin domain) with alpha-IIb/beta3 integrin ITGA2B:ITGB3 and alpha-V/beta-3 integrin ITGAV:ITGB3 (PubMed:37184585). Interacts with alpha5/beta1 integrin ITGA5:ITGB1 and alpha4/beta1 integrin ITGA4:ITGB (PubMed:37184585)
