L-selection (CD26L) is a cell surface adhesion protein constitutively expressed on all classes of human leukocytes. The L-Selectin glycoprotein is composed of a C-type lectin family domain at the amino terminus, an EGF-like domain, two short consensus repeat (SCR) sequences, a transmembrane domain and a short cytoplasmic tail. L-Selectin contains 7 potential N- linked glycosylation sites.
