Gene Information

General description

FcγRI/CD64, FcγRII/CD32, FcγRIII/CD16, and FcγRIV/CD16-2 represent the four known classes of IgG Fc receptors (FcγRs). FcγRII, FcγRIII, and FcγRIV are low-affinity receptors for monomeric IgG, whereas FcγRI is the only high-affinity FcγR. FcγRs play important roles in inflammatory cell activation, clearance, presentation of Ag, and maintenance of IgG homeostasis. In addition to binding immune complex (IC), FcγRs have been shown to bind non-IgG ligands. For example, FcγRII is shown to bind oxLDL, while FcγRIII binding to an E. coli component is reported to negatively regulate the function of macrophage receptor with collagenous structure (MARCO). FcyRII activation is also reported to transduce a negative regulatory signal against CD38 cross-linking-induced proliferation of resting mature B cells. Low affinity immunoglobulin gamma Fc region receptor II-a/b/c (IgG Fc receptor II-a/-b/-c, CDw32, Fc-gamma RII-a/-b/-c, Fc-gamma-RIIa/b/c, FcRII-a/-b/-c, CD32) are encoded by the FCGR2A/B/C (CD32, FCG2, IGFR2) genes in human (UniProt P12318, P31994, P31995; Gene ID 2212, 2213, 9103). The FcγRIIs encoded by the three genes are highly conserved in their extracellular portion, with significant variation in the transmembrane and intracellular regions. All three types of transcripts alternative splicing to generate additional isoforms.

Specificity

Clone 11B6 recognizes human FcγRIIa and FcγRIIc, but not FcγRIIb, by targeting a conserved cytoplasmic domain sequence in human FcγRIIa and FcγRIIc.

Immunogen

Epitope: Cytoplasmic domain.
Linear peptide corresponding to a cytoplasmic domain sequence identical in human FcγRIIa and FcγRIIc.

Application

Anti-FCGR2A/C Antibody, clone 11B6 is an antibody against FCGR2A/C for use in Immunohistochemistry (Paraffin), Immunocytochemistry, Western Blotting.
Immunocytochemistry Analysis: A representative lot detected FcγRIIc immunoreactivity in paraformaldehyde-fixed, Triton X-100-permeabilized human B cell lines carrying the FCGR2C-ORF allele, but not B cell lines with homozygous FCGR2C-STP alleles (Li, X., et al. (2013). Sci. Transl. Med. 5(216):216ra175).
Western Blotting Analysis: A representative lot detected recombinant FcγRIIc cytoplasmic (CY) domain GST fusion, but not FcγRIIb CY domain GST fusion (Li, X., et al. (2013). Sci. Transl. Med. 5(216):216ra175).

IgG immune complexes (ICs) promote autoimmunity through binding fragment crystallizable (Fc) γ-receptors (FcγRs). Of these, the highly prevalent FcγRIIa (CD32a) histidine (H)-131 variant (CD32aH) is strongly linked to human autoimmune diseases through unclear mechanisms. We show that, relative to the
