General description
P-selectin glycoprotein ligand 1 (UniProt: Q14242; also known as PSGL-1 Selectin P ligand, CD162) is encoded by the SELPLG gene (Gene ID: 6404) in human. Leukocytes express L-selectin ligands that are critical for leukocyte-leukocyte interactions at sites of inflammation. PSGL-1 is a predominant leukocyte L-selectin ligand that displays appropriate sialyl Lewis x (sLex)-like carbohydrate determinants for L-selectin recognition. It is a single-pass, mucin-like type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-17), which is subsequently cleaved off to produce a form that contains an extracellular domain (18-320), a transmembrane domain (321-341), and a cytoplasmic domain (342-412). The mature form is generated following the cleaved of the propeptide (aa 18-41) region. PSGL-1 is a SLe(x)-type proteoglycan, which through high affinity, calcium-dependent interactions with E-, P- and L-selectins mediates rapid rolling of leukocytes over vascular surfaces during the initial steps in inflammation. It is constitutively expressed on all human peripheral-blood T cells and is also expressed on skin-homing T cells. Clone HECA-452 can detect a human endothelial cell differentiation antigen (HECA) selectively expressed on high endothelium. In addition to reacting with high endothelium, it also shows some cross-reactivity with a set of monocytic cells. This clone is shown to block the majority of P-selectin binding to neutrophils.
