Function
Receptor for the invariable Fc fragment of immunoglobulin gamma (IgG). Optimally activated upon binding of clustered antigen-IgG complexes displayed on cell surfaces, triggers lysis of antibody-coated cells, a process known as antibody-dependent cellular cytotoxicity (ADCC). Does not bind free monomeric IgG, thus avoiding inappropriate effector cell activation in the absence of antigenic trigger (PubMed:11711607, PubMed:21768335, PubMed:22023369, PubMed:24412922, PubMed:25786175, PubMed:25816339, PubMed:28652325, PubMed:8609432, PubMed:9242542). Mediates IgG effector functions on natural killer (NK) cells. Binds antigen-IgG complexes generated upon infection and triggers NK cell-dependent cytokine production and degranulation to limit viral load and propagation. Involved in the generation of memory-like adaptive NK cells capable to produce high amounts of IFNG and to efficiently eliminate virus-infected cells via ADCC (PubMed:24412922, PubMed:25786175). Regulates NK cell survival and proliferation, in particular by preventing NK cell progenitor apoptosis (PubMed:29967280, PubMed:9916693). Fc-binding subunit that associates with CD247 and/or FCER1G adapters to form functional signaling complexes. Following the engagement of antigen-IgG complexes, triggers phosphorylation of immunoreceptor tyrosine-based activation motif (ITAM)-containing adapters with subsequent activation of phosphatidylinositol 3-kinase signaling and sustained elevation of intracellular calcium that ultimately drive NK cell activation. The ITAM-dependent signaling coupled to receptor phosphorylation by PKC mediates robust intracellular calcium flux that leads to production of pro-inflammatory cytokines, whereas in the absence of receptor phosphorylation it mainly activates phosphatidylinositol 3-kinase signaling leading to cell degranulation (PubMed:1825220, PubMed:23024279, PubMed:2532305). Costimulates NK cells and trigger lysis of target cells independently of IgG binding (PubMed:10318937, PubMed:23006327). Mediates the antitumor activities of therapeutic antibodies. Upon ligation on monocytes triggers TNFA-dependent ADCC of IgG-coated tumor cells (PubMed:27670158). Mediates enhanced ADCC in response to afucosylated IgGs (PubMed:34485821).; (Microbial infection) Involved in Dengue virus pathogenesis via antibody-dependent enhancement (ADE) mechanism. Secondary infection with Dengue virus triggers elevated levels of afucosylated non-neutralizing IgG1s with reactivity to viral envelope/E protein. Viral antigen-IgG1 complexes bind with high affinity to FCGR3A, facilitating virus entry in myeloid cells and subsequent viral replication.
Pathway

Subellular location
Cell membrane ; Single-pass type I membrane protein. Secreted. Note=Exists also as a soluble receptor.
Tissues
Expressed in natural killer cells (at protein level) (PubMed:2526846). Expressed in a subset of circulating monocytes (at protein level) (PubMed:27670158).
Structure
Forms a heterooligomeric complex with ITAM-containing signaling subunits, either a homodimer of CD247, a homodimer of FCER1G or a heterodimer of CD247 and FCER1G (PubMed:1825220, PubMed:2532305, PubMed:28652325). Interacts (via transmembrane domain) with signaling subunits; this interaction is a prerequisite for receptor complex expression on the cell surface and intracellular signal transduction (PubMed:1825220, PubMed:2532305, PubMed:28652325). Binds the Fc region of antigen-complexed IgG with a preference for IgG1 and IgG3 isotypes (PubMed:11711607, PubMed:21768335, PubMed:22023369, PubMed:8609432, PubMed:9242542). Interacts with CD2; this interaction is involved in NK cell activation and cytotoxicity (PubMed:23006327). Interacts with S100A4; this interaction inhibits PKC-dependent phosphorylation of FCGR3A (PubMed:23024279).
Post-translational modification
Glycosylated. Contains high mannose- and complex-type oligosaccharides. Glycosylation at Asn-180 is mandatory for high affinity binding to the Fc and for discrimination between fucosylated and afucosylated IgG glycoforms.; Undergoes rapid ectodomain shedding upon NK cell stimulation. The soluble form is produced by a proteolytic cleavage mediated by ADAM17. Repeated stimulation causes receptor shedding, a mechanism that allows for increased NK cell motility and detachment from opsonized target cells while avoiding activation-induced NK cell apoptosis.; Phosphorylated at RSSTR motif by PKC. The relevant physiological PKCs might be PRKCI, PRKCG, PRKCE, PRKCH and PRKCQ.
