• Description: Siglec-15 is a transmembrane glycoprotein in the Siglec family of sialic acid-binding immune regulatory molecules. 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. 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. It is expressed on osteoclasts, macrophages, and dendritic cells and binds to the sialyl-Tn antigen. This interaction induces the production of TGF-beta by tumor-associated macrophages. Siglec-15 function is important for osteoclast formation and TRANCE/RANK Ligand signaling in osteoclasts.
• Predicted N Terminal: Phe20
• Form: Lyophilized from a 0.2 μm filtered solution in PBS, NaCl, CHAPS and Trehalose.
• Bio-activity: Measured by its binding ability in a functional ELISA. When Neu5Ac(a2-6)GalNAc-PAA-biotin is immobilized onto a Streptavidin-coated plate, Recombinant Human Siglec-15 Fc Chimera binds with an ED50 of 150-900 ng/mL.
