The protein encoded by this gene is a low affinity receptor for the Fc region of gamma immunoglobulins (IgG). The encoded protein acts as a monomer and can bind either monomeric or aggregated IgG. This gene may function to capture immune complexes in the peripheral circulation. Several transcript variants encoding different isoforms have been found for this gene. A highly-similar gene encoding a related protein is also found on chromosome 1. [provided by RefSeq, Aug 2012]
A study in humans and mice identified FCGR3B as a neutrophil marker in a spatiotemporal single-cell atlas of human skin wound healing [Liu et al. DOI:10.1016/j.stem.2024.11.013]. In a separate investigation in humans, mice, and rats, FCGR3B was identified as a candidate gene showing strong interactions in a protein-protein interaction network with other candidate genes in acute myocardial infarction [Li et al. DOI:10.1038/s41598-025-94820-6]. A study in mice demonstrated that following clodronate liposome pre-treatment and controlled cortical impact injury, a distinct CD115+/Ly6Chi monocyte population emerges in circulation, correlating with neuroprotection, blood-brain barrier stability, and improved cerebral blood flow [Gudenschwager Basso et al. DOI:10.1186/s12974-024-03032-8].
