Background Human CD32 group consists of FcγRIIA, B and C proteins that share 94-99% amino acid identity in their extracellular domains but differ substantially in their transmembrane and cytoplasmic domains. CD32A, also known as FcγRIIA, is a surface receptor protein and part of a large population of B cell co-receptors. The protein is found on phagocytic cells such as macrophages and neutrophils, and it is involved in the process of phagocytosis and clearing of immune complexes. It has low-affinity for IgG antibodies and down-regulates antibody production in the presence of IgG. This feedback loop acts to lower the production of IgG by B cells when there is a surplus in the body. Therefore, targeting CD32A may represent an approach to immunotherapy of B-cell malignancies.
