Additionally, by conducting mass spectrometry on Siglec-9 ligands isolated from carcinoma cell lines, Läubli et al. identified the heavily-glycosylated protein Lectin Galactoside-binding soluble 3-binding protein (LGALS3BP) as a novel ligand for Siglec-9 (46). The gene discussed is LGALS3BP; the disease is carcinoma.
