siglec9 (HGMWapproved symbol SIGLEC9) a member of the sialic acidbinding Iglike lectin (Siglec) family, which belongs to the immunoglobulin superfamily (IgSF). SIGLEC9 shows a high degree of homology to many members of the siglec family, including siglec7 (80%), siglec8 (72%), siglec5 (65%), and CD33 (64%). This high degree of homology is also conserved in the extracellular Iglike domains. They are characterized by an Nterminal Iglike Vtype domain which mediates sialic acid binding, followed by varying numbers of Iglike C2type domainsSiglec9 with a hydrophobic signal peptide, an Nterminal IglikeVtype domain, two Iglike C2type domains, a transmembrane region and a cytoplasmic tail. - Proteine/Peptide
