N-TERMINAL DOMAIN OF SIALOADHESIN (MOUSE) IN COMPLEX WITH GLYCOPEPTIDE
Overview
Sialoadhesin is a sialic acid-binding immunoglobulin-like lectin (Siglec), expressed on subsets of macrophages. It is a model system for Siglec, receptor-mediated cell surface interactions through binding of sialylated, glycoconjugates. The N-terminal sialoadhesin domain can mediate sialic, acid-binding on its own. The structure of this domain has been determined, in complex with a sialic acid-containing heptapeptide, (Ala-Gly-His-Thr(Neu5Ac)-Trp-Gly-His). The affinity of sialoadhesin for, this ligand is four times higher than the affinity for the natural linkage, 2,3'-sialyllactose. The structure of the glycopeptide complex suggests, strategies for ligand optimization and provides possible explanations for, the observed differences in specificities among the Siglecs.
