Summary: Enables IgG binding activity. Involved in several processes, including cellular response to amyloid-beta; negative regulation of neutrophil apoptotic process; and regulation of response to endoplasmic reticulum stress. Located in cell surface and recycling endosome.

What's a GeneRIF?

Data shew that he up-regulation of Fc gamma RIIB (FcgammaRIIB) expression in macrophages might suppress cell phagocytosis and chemotaxis.
Title: [Up-regulated expression of FcγRIIB inhibits phagocytosis and chemotaxis of macrophages].
These results are consistent with a model where mAb BGD6 binds through its Fab portion to a approximately 110 kDa protein and the Fc tail interacts with Fc gamma RIIB (CD32).[Fc gamma RIIB]
Title: The low affinity IgG receptor Fc gamma RIIB contributes to the binding of the mast cell specific antibody, mAb BGD6.
FcgammaRIIb2 in rat liver sinusoidal endothelial cells is used as both a recycling receptor and a receptor for efficient immune complexes clearance.
Title: Receptor-mediated endocytosis of immune complexes in rat liver sinusoidal endothelial cells is mediated by FcgammaRIIb2.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
