Low affinity immunoglobulin gamma Fc region receptor III-A is a receptor for the Fc portion of immunoglobulin G, and is involved in the elimination of antigen-antibody complexes from the circulation, as well as other antibody-dependent responses. FCGR3A needs to associate with the gamma subunit of Fc epsilon. The FCGR3A receptor is expressed on natural killer cells as an integral membrane glycoprotein anchored through a transmembrane peptide, while FCGR3B is expressed on polymorphonuclear neutrophils where the receptor is anchored through a phosphatidylinositol linkage. In addition, FCGR3A is expressed on macrophages, subpopulation of T-cells, immature thymocytes and placental trophoblasts. FCGR3A mediates antibody-dependent cellular cytotoxicity and other antibody-dependent responses, such as phagocytosis. FCGR3A gene mutations are linked with susceptibility to recurrent viral infections, susceptibility to systemic lupus erythematosus, and alloimmune neonatal neutropenia.

低亲和力免疫球蛋白 γ Fc 区受体 III-A 是免疫球蛋白 G 的 Fc 部分的受体，参与从循环中消除抗原-抗体复合物以及其他抗体依赖性反应。 FCGR3A 需要与 Fc epsilon 的 γ 亚基结合。 FCGR3A 受体作为通过跨膜肽锚定的完整膜糖蛋白在自然杀伤细胞上表达，而 FCGR3B 在多形核中性粒细胞上表达，其中受体通过磷脂酰肌醇键锚定。 此外，FCGR3A 在巨噬细胞、T 细胞亚群、未成熟胸腺细胞和胎盘滋养细胞上表达。 FCGR3A 介导抗体依赖性细胞毒性和其他抗体依赖性反应，例如吞噬作用。 FCGR3A 基因突变与对复发性病毒感染的易感性、对系统性红斑狼疮的易感性和同种免疫新生儿中性粒细胞减少症有关。
