General description

Interactions between P-selectin and P-selectin glycoprotein ligand-1 (PSGL-1) mediate the earliest “rolling” of leukocytes on the lumenal surface of endothelial cells at sites of inflammation. To date, the primary role of PSGL-1 in mediating the interaction between neutrophils and P-selectin has been well documented. MAB4092 completely blocks recognition of PSGL-1 by either P-selectin or by L-selectin, but does not affect leukocyte recognition of E-selectin. Two color flow cytometry of normal leukocytes has demonstrated that PSGL-1 is expressed on essentially all blood neutrophils, NK cells, blood cells, T cells, and monocytes, but PSGL-1 stains B cells at significantly lower levels than other cell types. Variation in tyrosine sulfation during B cell differentiation may affect the stability of B cells to interact with P- and L-selectin. {Snapp, KR et al 1998}.


P-selectin glycoprotein ligand-1 (PSGL-1). The antibody epitope was mapped to a site within a consensus tyrosine sulfation motif of PSGL-1, previously shown to be essential for interaction with P-selectin (and now shown to be essential for recognition of PSGL-1 by L-selectin). {Snapp KR et al. 1998}. The binding of KPL-1 to human PSGL-1 on HL-60 cells does not require sulfation {Thatte, A et al 2002}.
