Myeloid cell surface antigen CD33 (Siglec-3)

Target (abbrv.) Siglec-3

Somalogic ID (Sequence ID) SL005215 (3166-92_1)
Entrez Gene Symbol CD33
UniProt ID P20138
UniProt Comment
  • Putative adhesion molecule of myelomonocytic-derived cells that mediates sialic-acid dependent binding to cells. Preferentially binds to alpha-2,6-linked sialic acid. The sialic acid recognition site may be masked by cis interactions with sialic acids on the same cell surface. In the immune response, may act as an inhibitory receptor upon ligand induced tyrosine phosphorylation by recruiting cytoplasmic phosphatase(s) via their SH2 domain(s) that block signal transduction through dephosphorylation of signaling molecules. Induces apoptosis in acute myeloid leukemia (in vitro).
Targeted by drugs (based on IPA annotation)
  • arsenic trioxide/gemtuzumab ozogamicin/tretinoin
  • gemtuzumab ozogamicin
Biomarker applications (based on IPA annotation)
  • efficacy

All locus annotations are based on the sentinel SNP (rs10421385) and 27 proxy variant(s) that is/are in linkage disequilibrium r2 ≥ 0.8. Linkage disequilibrium is based on data from the 1000 Genomes Project, phase 3 version 5, European population and was retrieved using SNiPA's Block Annotation feature.
