Primary Identifier | MGI:95500 | Organism | mouse, laboratory |
Chromosome | 1 | NCBI Gene Number | 14131 |
Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Enables IgG binding activity and IgG receptor activity. Acts upstream of or within several processes, including antibody-dependent cellular cytotoxicity; phagocytosis; and positive regulation of hypersensitivity. Located in external side of plasma membrane. Is expressed in liver and spleen. 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 human FCGR2A (Fc gamma receptor IIa). PHENOTYPE: Homozygotes for a targeted null mutation lack IgG-mediated mast cell degranulation and have impaired IgG-dependent anaphylaxis and Arthus reactions. [provided by MGI curators] |
