Low affinity immunoglobulin gamma Fc region receptor II-a/b (FCG2A/B)

Target (abbrv.) FCG2A/B
Target (full name) Low affinity immunoglobulin gamma Fc region receptor II-a/b
Somalogic ID (Sequence ID) SL017613 (3310-62_1)
Entrez Gene Symbol FCGR2A
UniProt ID P12318, P31994
UniProt Comment
  • P12318: Binds to the Fc region of immunoglobulins gamma. Low affinity receptor. By binding to IgG it initiates cellular responses against pathogens and soluble antigens. Promotes phagocytosis of opsonized antigens.
  • P31994: Receptor for the Fc region of complexed or aggregated immunoglobulins gamma. Low affinity receptor. Involved in a variety of effector and regulatory functions such as phagocytosis of immune complexes and modulation of antibody production by B-cells. Binding to this receptor results in down-modulation of previous state of cell activation triggered via antigen receptors on B-cells (BCR), T-cells (TCR) or via another Fc receptor. Isoform IIB1 fails to mediate endocytosis or phagocytosis. Isoform IIB2 does not trigger phagocytosis.

All locus annotations are based on the sentinel SNP (rs17413015) and 7 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.
