| 背景介绍 | Enables IgG binding activity. Involved in several processes, including Fc receptor-mediated immune complex endocytosis; nervous system development; and regulation of response to endoplasmic reticulum stress. Acts upstream of or within several processes, including antigen processing and presentation of exogenous peptide antigen via MHC class II; negative regulation of immune effector process; and regulation of phagocytosis. Located in cell body; dendritic spine; and external side of plasma membrane. Is expressed in several structures, including adipose tissue; bone; liver; lung; and spleen. Used to study malaria and systemic lupus erythematosus. Human ortholog(s) of this gene implicated in several diseases, including autoimmune disease (multiple); dengue disease (multiple); hematologic cancer (multiple); leukopenia (multiple); and malaria (multiple). Orthologous to several human genes including FCGR2A (Fc gamma receptor IIa) and FCGR2B (Fc gamma receptor IIb). [provided by Alliance of Genome Resources, Jul 2025] |

| 功能 | Receptor for the Fc region of complexed immunoglobulins gamma. Low affinity receptor. Involved in a variety of effector and regulatory functions such as phagocytosis of antigen-antibody complexes from the circulation and modulation of antibody production by B-cells. Isoform IIB1 and isoform IIB1' form caps but fail to mediate endocytosis or phagocytosis. Isoform IIB2 can mediate the endocytosis of soluble immune complexes via clathrin-coated pits. Isoform IIB1 and isoform IIB2 can down-regulate B-cell, T-cell, and mast cell activation when coaggregated to B-cell receptors for AG (BCR), T-cell receptors for AG (TCR), and Fc receptors, respectively. |

| 组织表达 | Widely expressed by cells of hemopoietic origin. The isoforms are differentially expressed. Isoform IIB1 is preferentially expressed by cells of the lymphoid lineage, isoform IIB2 by cells of the myeloid lineage, and isoform IIB3 is released by macrophages and is present in the serum. Isoform IIB1' is expressed in myeloid and lymphoid cell lines, in normal spleen cells, and in resting or LPS-activated B-cells but is not detected in mesenteric lymph node cells. |
