FUNCTION: Receptor for the Fc region of complexed or aggregated immunoglobulins gamma. Low affinity receptor. Involved in a variety of effector and regulatory functions such as phagocytosis of immune complexes and modulation of antibody production by B- cells. Binding to this receptor results in down-modulation of previous state of cell activation triggered via antigen receptors on B-cells (BCR), T-cells (TCR) or via another Fc receptor. Isoform IIB1 fails to mediate endocytosis or phagocytosis. Isoform IIB2 does not trigger phagocytosis. SUBUNIT: Isoform IIB1 interacts with measles virus N protein. N protein is released in the blood following lysis of measles infected cells. This interaction presumably block inflammatory immune response. Interacts with INPP5D/SHIP1. SUBCELLULAR LOCATION: Cell membrane; Single-pass type I membrane protein. ALTERNATIVE PRODUCTS: Event=Alternative splicing; Named isoforms=3; Name=IIB1; IsoId=P31994-1; Sequence=Displayed; Name=IIB2; IsoId=P31994-2; Sequence=VSP_002643; Name=IIB3; IsoId=P31994-3; Sequence=VSP_002642; TISSUE SPECIFICITY: Is the most broadly distributed Fc-gamma- receptor. Expressed in monocyte, neutrophils, macrophages, basophils, eosinophils, Langerhans cells, B-cells, platelets cells and placenta (endothelial cells). Not detected in natural killer cells. DOMAIN: Contains 1 copy of a cytoplasmic motif that is referred to as the immunoreceptor tyrosine-based inhibitor motif (ITIM). This motif is involved in modulation of cellular responses. The phosphorylated ITIM motif can bind the SH2 domain of several SH2- containing phosphatases. DISEASE: Note=A chromosomal aberration involving FCGR2B is found in a follicular lymphoma. Translocation t(1;22)(q22;q11). The translocation leads to the hyperexpression of the receptor. This may play a role in the tumor progression. SIMILARITY: Contains 2 Ig-like C2-type (immunoglobulin-like) domains. CAUTION: Has sometimes been attributed to correspond to FcR-IIC. SEQUENCE CAUTION: Sequence=CAA35645.1; Type=Erroneous initiation; WEB RESOURCE: Name=Atlas of Genetics and Cytogenetics in Oncology and Haematology; URL="http://atlasgeneticsoncology.org/Genes/FCGR2BID397.html"; GENE SYNONYMS: CD32 FCG2 IGFR2.
