The encoded protein acts as a monomer and can bind either monomeric or aggregated IgG. This gene may function to capture immune complexes in the peripheral circulation. Several transcript variants encoding different isoforms have been found for this gene. A highly-similar gene encoding a related protein is also found on chromosome 1. [provided by RefSeq, Aug 2012]. * **UniProt Summary**: Receptor for the Fc region of immunoglobulins gamma. Low affinity receptor. Binds complexed or aggregated IgG and also monomeric IgG. Contrary to III-A, is not capable to mediate antibody-dependent cytotoxicity and phagocytosis. May serve as a trap for immune complexes in the peripheral circulation which does not activate neutrophils. No Pfam Domain information is available for this gene. |IgG binding| |secretory granule membrane| |anchored component of membrane| |neutrophil degranulation| |neutrophil activation involved in immune response| |neutrophil mediated immunity| |neutrophil activation| |granulocyte activation| |leukocyte degranulation| |myeloid leukocyte mediated immunity| |myeloid cell activation involved in immune response| |myeloid leukocyte activation| |leukocyte activation involved in immune response| |cell activation involved in immune response| |regulated exocytosis| |leukocyte mediated immunity| |exocytosis| |leukocyte activation| |secretion by cell| |export from cell| |cell activation| |immune effector process| |secretion| |immune response| |extracellular region| |vesicle-mediated transport| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp27|Pimelic-diphenylamide-106 0.5μM R00 exp27]]|-1.99| |[[:results:exp393|Resminostat 0.5μM R07 exp393]]|-1.88| |[[:results:exp533|TNF-alpha 44ng/ml R08 exp533]]|-1.72| |[[:results:exp482|Fas-L 44ng/ml R08 exp482]]|-1.71| ^Gene^Correlation^ |[[:human genes:h:hgc6.3|HGC6.3]]|0.446| Global Fraction of Cell Lines Where Essential: 0/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|0/28| |bone|0/26| |breast|0/33| |central nervous system|0/56| |cervix|0/4| |colorectal|0/17| |esophagus|0/13| |fibroblast|0/1| |gastric|0/16| |kidney|0/21| |liver|0/20| |lung|0/75| |lymphocyte|0/16| |ovary|0/26| |pancreas|0/24| |peripheral nervous system|0/16| |plasma cell|0/15| |prostate|0/1| |skin|0/24| |soft tissue|0/9| |thyroid|0/2| |upper aerodigestive|0/22| |urinary tract|0/29| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 19070 * **Expression level (log2 read counts)**: -7.68 {{:chemogenomics:nalm6 dist.png?nolink |}}
