Fc gamma RIIIA/CD16a is a low/intermediate affinity receptor for polyvalent immune-complexed IgG. It is involved in phagocytosis, secretion of enzymes and inflammatory mediators, antibody-dependent cytotoxicity, and clearance of immune complexes. In humans, a single nucleotide polymorphism (T230A) creates high binding (176V) and low binding (176F) forms that may influence susceptibility to autoimmune diseases or response to therapeutic IgG antibodies. Fc gamma RIIIA surface expression requires interaction with an accessory chain, either the common gamma -chain or CD3 zeta. Glycosylation patterns, electrophoretic mobility, and binding affinity appear to differ between NK cell and monocyte Fc gamma RIIIA. Shed forms of both Fc gamma RIIIA and Fc gamma RIIIB can be generated by proteolytic cleavage and retain binding activity. Shedding from monocytes and macrophages can be triggered by cell activation or phagocytosis. Soluble Fc gamma RIII circulates in normal plasma and is elevated in rheumatoid arthritis and in coronary artery diseases.
