Preparation and Storage

Background: Siglec-15

Siglec-15 is a transmembrane glycoprotein in the Siglec family of sialic acid-binding immune regulatory molecules (1). Mature human Siglec-15 consists of a 244 amino acid (aa) extracellular domain (ECD) with two Ig-like domains, a 21 aa transmembrane segment, and a 44 aa cytoplasmic domain (2). Within the ECD, human Siglec-15 shares 85% aa sequence identity with mouse and rat Siglec-15. Alternative splicing generates an additional isoform that lacks the signal peptide and first Ig-like domain. Siglec-15 associates with the signaling molecules DAP12 and DAP10 (2-5). It is expressed on osteoclasts, macrophages, and dendritic cells (2-6) and binds to the sialyl-Tn antigen (2, 3, 6). This interaction induces the production of TGF-beta by tumor-associated macrophages (3). Siglec-15 function is important for osteoclast formation and TRANCE/RANK Ligand signaling in osteoclasts (4-6).
