Lectin domain peptides from selectins interact with both cell surface ligands and Ca2+ ions

Selectins are receptors that mediate leukocyte adhesion to platelets or endothelial cells through Ca(2+)-dependent interactions with cell surface oligosaccharides. We found that peptides corresponding to residues 23-30, 54-63, and 70-79 of the N-terminal lectin domain of P-selectin inhibited leukocy...
