This protein contains two conserved domains, an N-terminal RUN domain and a C-terminal DUF4206 domain. The RUN domain is involved in Ras-like GTPase signaling, and the DUF4206 domain contains a diacylglycerol (DAG) binding-like motif. Mutation in this gene results in deletion of the DAG binding-like motif and causes a recessive ataxia. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Apr 2014]. * **UniProt Summary**: Inhibits PIK3C3 activity; under basal conditions negatively regulates PI3K complex II (PI3KC3-C2) function in autophagy. Negatively regulates endosome maturation and degradative endocytic trafficking and impairs autophagosome maturation process. Can sequester UVRAG from association with a class C Vps complex (possibly the HOPS complex) and negatively regulates Rab7 activation (PubMed:20974968, PubMed:21062745). {ECO:0000269|PubMed:20974968, ECO:0000269|PubMed:21062745}. |RUN| |negative regulation of autophagosome maturation| |negative regulation of phosphatidylinositol 3-kinase activity| |negative regulation of lipid kinase activity| |negative regulation of phospholipid metabolic process| |regulation of autophagosome maturation| |negative regulation of macroautophagy| |multivesicular body sorting pathway| |negative regulation of endocytosis| |regulation of phosphatidylinositol 3-kinase activity| |regulation of lipid kinase activity| |negative regulation of protein complex disassembly| |negative regulation of lipid metabolic process| |negative regulation of autophagy| |regulation of phospholipid metabolic process| |regulation of protein complex disassembly| |late endosome| |regulation of macroautophagy| |regulation of endocytosis| |negative regulation of kinase activity| |lysosome| |negative regulation of cellular catabolic process| |early endosome| |autophagy| |process utilizing autophagic mechanism| |negative regulation of transferase activity| |negative regulation of catabolic process| |phagocytosis| |regulation of autophagy| |regulation of lipid metabolic process| |negative regulation of phosphorylation| |negative regulation of transport| |regulation of vesicle-mediated transport| |endocytosis| |negative regulation of phosphate metabolic process| |negative regulation of phosphorus metabolic process| |import into cell| |intracellular membrane-bounded organelle| |negative regulation of cellular component organization| |negative regulation of catalytic activity| |regulation of cellular catabolic process| |regulation of kinase activity| |regulation of transferase activity| |Golgi apparatus| |regulation of catabolic process| |negative regulation of molecular function| |regulation of organelle organization| |regulation of phosphorylation| |regulation of phosphate metabolic process| |regulation of phosphorus metabolic process| |cellular catabolic process| |regulation of transport| |vesicle-mediated transport| \\ === CRISPR Data === No hits were found. ^Gene^Correlation^ |[[:human genes:h:hgc6.3|HGC6.3]]|0.4| 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**: 3450 * **Expression level (log2 read counts)**: 6.02 {{:chemogenomics:nalm6 dist.png?nolink |}}
