L-selectin, also known as CD62L, is a cell adhesion molecule found on leukocytes. It belongs to the selectin family of proteins, which recognise sialylated carbohydrate groups. It is cleaved by ADAM17.

summary_text = SELL is a cell surface component that is a member of a family of adhesion/homing receptors which play important roles in leukocyte-endothelial cell interactions. The molecule is composed of multiple domains: one homologous to lectins, one to epidermal growth factor, and two to the consensus repeat units found in C3/C4 binding proteins.

*GlyCAM-1, found in the high endothelial venules of the lymph nodes.
*CD34, found on endothelial cells.
*MadCAM-1, found on endothelial cells of gut associated lymphoid tissue.
*PSGL-1, binds with low affinity.


L-selectin acts as a "homing receptor" for leukocytes to enter secondary lymphoid tissues via the high endothelial venules. Ligands present on endothelial cells will bind to leukocytes expressing L-selectin, which causes the leukocytes to become localised at that pointcite book | title=Robbins Pathologic Basis of Disease| last=Cotran| coauthors=Kumar, Collins| publisher=W.B Saunders Company| location=Philadelphia| id=0-7216-7335-X] . The receptor is also found on the cell surfaces of "naive" T cells, which have not yet encountered their specific antigen. This surface expression is lost after the cells are activated.
