Summaries for FCGR2A Gene

Entrez Gene Summary for FCGR2A Gene

  • This gene encodes one member of a family of immunoglobulin Fc receptor genes found on the surface of many immune response cells. The protein encoded by this gene is a cell surface receptor found on phagocytic cells such as macrophages and neutrophils, and is involved in the process of phagocytosis and clearing of immune complexes. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2008]

GeneCards Summary for FCGR2A Gene

FCGR2A (Fc Fragment Of IgG, Low Affinity IIa, Receptor (CD32)) is a Protein Coding gene. Diseases associated with FCGR2A include cystic fibrosis and asymptomatic dengue. Among its related pathways are GPCR Pathway and Phospholipase-C Pathway. GO annotations related to this gene include IgG binding. An important paralog of this gene is FCRL2.

UniProtKB/Swiss-Prot for FCGR2A Gene

  • 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.
