Function

[SN_MOUSE] Acts as an endocytic receptor mediating clathrin dependent endocytosis. Macrophage-restricted adhesion molecule that mediates sialic-acid dependent binding to lymphocytes, including granulocytes, monocytes, natural killer cells, B-cells and CD8 T-cells (By similarity). Preferentially binds to alpha-2,3-linked sialic acid. Binds to SPN/CD43 on T-cells. May play a role in hematopoiesis. May act as a counter-receptor for CLEC10A in lymph node.^[1]

Publication Abstract from PubMed

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.
