Promotes the exchange of GDP to GTP, converting inactive GDP-bound RAB12 into its active GTP-bound form (PubMed:20937701). Regulates autophagy in response to starvation through RAB12 activation. Starvation leads to ULK1/2-dependent phosphorylation of Ser-472 and Ser-490, which in turn allows recruitment of 14-3-3 adapter proteins and leads to up-regulation of GEF activity towards RAB12 (By similarity). Also plays a role in protein transport from recycling endosomes to lysosomes, regulating, for instance, the degradation of the transferrin receptor and of the amino acid transporter PAT4 (PubMed:20937701). Starvation also induces phosphorylation at Tyr-858, which leads to up-regulated GEF activity and initiates autophagy (By similarity). {ECO:0000250|UniProtKB:A2RT67, ECO:0000269|PubMed:20937701}. |DENN| |dDENN| |Rab guanyl-nucleotide exchange factor activity| |endosome to lysosome transport| |lysosomal transport| |vacuolar transport| |cellular protein catabolic process| |protein catabolic process| |cellular macromolecule catabolic process| |macromolecule catabolic process| |organonitrogen compound catabolic process| |intracellular transport| |organic substance catabolic process| |cellular catabolic process| |establishment of localization in cell| |vesicle-mediated transport| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp526|Sulforaphane 9μM R08 exp526 no dilution day6]]|-2| |[[:results:exp51|Nifuroxazide 1μM R01 exp51]]|1.72| |[[:results:exp359|FK-506 30μM R07 exp359]]|1.83| |[[:results:exp376|Losmapimod 1μM R07 exp376]]|1.95| |[[:results:exp342|Calcium Ionophore 0.4μM R07 exp342]]|1.96| ^Gene^Correlation^ |[[:human genes:r:rrm1|RRM1]]|0.443| 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**: 8843 * **Expression level (log2 read counts)**: 4.93 {{:chemogenomics:nalm6 dist.png?nolink |}}
