CD16 is the type III Fcγ receptor. In humans, it exists in two different forms: FcγRIIIa (CD16a) and FcγRIIIb (CD16b), which have 96% sequence similarity in the extracellular immunoglobulin binding regions. While FcγRIIIa is expressed on mast cells, macrophages, and natural killer cells as a transmembrane … See more CD16, also known as FcγRIII, is a cluster of differentiation molecule found on the surface of natural killer cells, neutrophils, monocytes, macrophages, and certain T cells. CD16 has been identified as Fc receptors See more The crystal structures of FcεRIα, FcγRIIa, FcγRIIb and FcγRIII have been experimentally determined.

The test helps in measuring the circulating NK cells in the body. The percentage of CD56+ NK cells in peripheral blood in normal healthy individuals varies from 5% to 29%.
WebCD16 exists as a transmembrane form in NK cells, macrophages and cultured monocytes with a 25 amino acid cytoplasmic tail which further connects with other receptors. The transmembrane form binds complexed IgG and mediates phagocytosis and antibody-dependent cellular cytotoxicity (ADCC). [ 6] [ 7] Target description
