However, the encoded protein does not appear to be a catalytically active phosphatase because it lacks several amino acids in the catalytic pocket. This protein contains a Guanine nucleotide exchange factor (GEF) domain which is necessary for its role in growth and differentiation. Mutations in this gene have been associated with Charcot-Marie-Tooth disease 4B3. Pseudogenes of this gene have been defined on chromosomes 1 and 8. [provided by RefSeq, Dec 2014]. * **UniProt Summary**: Probable pseudophosphatase. Lacks several amino acids in the catalytic pocket which renders it catalytically inactive as a phosphatase. The pocket is however sufficiently preserved to bind phosphorylated substrates, and maybe protect them from phosphatases. Inhibits myoblast differentiation in vitro and induces oncogenic transformation in fibroblasts. According to PubMed:20937701, may function as a guanine nucleotide exchange factor (GEF) activating RAB28. Promotes the exchange of GDP to GTP, converting inactive GDP-bound Rab proteins into their active GTP-bound form. {ECO:0000269|PubMed:20937701, ECO:0000269|PubMed:9537414}. |DENN| |SBF2| |PH| |dDENN| |uDENN| |GRAM| |Myotub-related| |phosphatase regulator activity| |Rab guanyl-nucleotide exchange factor activity| |protein tyrosine/serine/threonine phosphatase activity| |phosphatase activity| |phosphatidylinositol biosynthetic process| |phosphatidylinositol metabolic process| |glycerophospholipid biosynthetic process| |protein dephosphorylation| |glycerolipid biosynthetic process| |phospholipid biosynthetic process| |nuclear body| |glycerophospholipid metabolic process| |dephosphorylation| |phospholipid metabolic process| |glycerolipid metabolic process| |regulation of GTPase activity| |organophosphate biosynthetic process| |spermatogenesis| |male gamete generation| |lipid biosynthetic process| |gamete generation| |perinuclear region of cytoplasm| |multicellular organismal reproductive process| |sexual reproduction| |multicellular organism reproduction| |organophosphate metabolic process| |endoplasmic reticulum membrane| |cellular lipid metabolic process| |multi-organism reproductive process| |lipid metabolic process| |regulation of hydrolase activity| |reproductive process| |reproduction| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp240|Pyridostatin 4μM R05 exp240]]|2.26| ^Gene^Correlation^ |[[:human genes:e:ercc2|ERCC2]]|0.417| 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**: 10768 * **Expression level (log2 read counts)**: 8.32 {{:chemogenomics:nalm6 dist.png?nolink |}}
