What is FCGR2A protein?

FCGR2A (Fc gamma receptor IIa) gene is a protein coding gene which situated on the long arm of chromosome 1 at locus 1q23. This gene encodes one member of a family of immunoglobulin Fc receptor genes found on the surface of many immune response cells. The FCGR2A 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. FCGR2A is expressed on cells of both myeloid and lymphoid lineages as well as on cells of non-hematopoietic origin. This protein is consisted of 317 amino acids and is approximately 35 kDa.

What is the Function of FCGR2A protein?

Associated with an ITAM (immunoreceptor tyrosine-based activation motif)- bearing adapter subunit, FCGR2A delivers an activating signal upon ligand binding, and results in the initiation of inflammatory responses including cytolysis, phagocytosis, degranulation and cytokine production. It can also bind to IgG antibodies to promote the phagocytosis and destruction of immune cells (such as monocytes, macrophages, and dendritic cells) against pathogens or foreign bodies labeled by antibodies, thereby enhancing antibody-mediated cytotoxicity.

FCGR2A Related Signaling Pathway

When FCGR2A binds to the Fc part of IgG antibody, it activates the downstream signaling pathway through the ITAM region in its cytoplasm. These signaling pathways, including Syk tyrosine kinase, PI3K/Akt, NF-κB, etc., regulate the activation, proliferation, and inflammatory response of macrophages, dendritic cells, and B cells.

FCGR2A Related Diseases

FCGR2A gene mutation may lead to the occurrence of autoimmune diseases, such as rheumatoid arthritis, systemic lupus erythematosus and so on. It may also lead to the occurrence of allergic diseases, such as asthma and allergic rhinitis. Other research reports FCGR2A functional genetic variant is associated with susceptibility to severe malarial anaemia in Ghanaian children.

Bioapplications of FCGR2A

The anti-ige antibody drug Omalizumab inhibits the FCGR2A signaling pathway by binding to IgE antibodies, thereby reducing allergic reactions. At the same time, some studies are exploring the use of gene editing technology to change the expression level of FCGR2A in order to achieve better immunomodulatory effects.
