Abstrakt: P-Selectin Glycoprotein Ligand-1 (PSGL-1) is a dimeric mucin-like transmembrane glycoprotein identified as a functional ligand for P-Selectin (1). Functional activity of PSGL-1 is dependent upon at least two key posttranslational modifications made to the amino terminus. Core 2 O-linked oligosaccharide structures at Thr16 bearing the sialyl-Lewisx (SLex) antigen and sulfation of one or more of the NH2-terminal tyrosine it has been shown that a polypeptide containing the NH2-terminal 47 amino acid sequence of human PSGL-1 is sufficient for high-affinity binding to P-Selectin (2).
