Background: E-Selectin (CD62E)/P-Selectin (CD62P)
E-Selectin (CD62E) and P-Selectin (CD62P) are members of the Selectin/LECAM family of molecules. E- and P-Selectin are type I transmembrane glycoproteins that contain an N-terminal calcium-dependent C-type lectin domain, one EGF-like repeat, multiple sushi domains, and a transmembrane segment followed by a short cytoplasmic tail. Typically, the ligands for E-and P-Selectin are carbohydrates that contain a sialyl-Lewis X (sLeX) motif that appears on select O- and N-linked glycans and glycosphingolipids. Human E-Selectin is 95-115 kDa is size and expressed by vascular endothelium. It has a number of ligands, not all of which are shared between the human and rodent systems. For example human E-Selectin binds L-Selectin, CD44/HCELL and a poorly characterized pronase-insensitive ganglioside, none of which are recognized by mouse E-Selectin. By contrast, mouse E-Selectin binds E-Selectin Ligand whereas human E-Selectin does not. Other ligands identified for human E-Selectin include PSGL-1, CD43, Mac-1, CD66, Endoglycan and Podocalyxin-like protein. Human P-Selectin is 130-140 kDa in size, and expressed platelets and vascular endothelium. It primarily binds sLeX on O-glycans, including PSGL-1 and endoglycan. Functionally, Selectins induce leukocyte rolling on endothelial cell surfaces, an effect that activates neighboring alpha 2 beta 2/LFA-1 and slows leukocyte migration. Although the extracellular domains of human E- and P-Selectin show only 36% amino acid (aa) sequence identity, over the first 180 aa (out of >500 aa), E- and P- Selectin demonstrate 62% aa sequence identity.
