L-selectin function

L-selectin, also known as CD62L, is a cell adhesion molecule found on the cell surface of leukocytes, and the blastocyst. It is coded for in the human by the SELL gene.

L-selectin shedding does not occur in cells with very low expression levels of ADAM17.In addition, thymocytes derived from ADAM17-deficient mice do not show a reduction in surface L-selectin levels in response to TPA stimulation (which has been interpreted as a lack of shedding).
