Background: Siglec-1/CD169

Siglec-1, also known as Sialoadhesin or CD169, is a 175-185 kDa type I transmembrane glycoprotein belonging to the Siglec family of sialic acid specific I-type lectins within the immunoglobulin superfamily. Mouse Siglec-1 contains a 1619 amino acid (aa) extracellular domain (ECD) with one Ig-like V-set domain and 16 Ig-like C2-set domains. The ECD shares 73% and 83% aa sequence identity with human and rat Siglec-1, respectively. Alternate splicing generates two soluble isoforms containing either 16 or the first 3 Ig-like domains. Siglec-1 is expressed by some tissue macrophages, dendritic cells and circulating monocytes during certain infections. It binds sialylated molecules including MMR, MGL1/CD301a, MUC1, PSGL-1 and CD43.
