該基因編碼許多免疫應答細胞表面發現的免疫球蛋白Fc受體基因家族的一個成員。該基因編碼的蛋白質是一種在巨噬細胞和中性粒細胞等吞噬細胞上發現的細胞表面受體，參與吞噬和清除免疫復合物的過程。選擇性剪接導致多個轉錄變體。
This gene encodes one member of a family of immunoglobulin Fc receptor genes found on the surface of many immune response cells. The protein encoded by this gene is a cell surface receptor found on phagocytic cells such as macrophages and neutrophils, and is involved in the process of phagocytosis and clearing of immune complexes. Alternative splicing results in multiple transcript variants.
