CC -!- FUNCTION: As a component of the GATOR1 complex functions as an
CC inhibitor of the amino acid-sensing branch of the TORC1 pathway. The
CC GATOR1 complex strongly increases GTP hydrolysis by RRAGA and RRAGB
CC within RRAGC-containing heterodimers, thereby deactivating RRAGs,
CC releasing mTORC1 from lysosomal surface and inhibiting mTORC1
CC signaling. The GATOR1 complex is negatively regulated by GATOR2 the
CC other GATOR subcomplex in this amino acid-sensing branch of the TORC1
CC pathway. {ECO:0000250|UniProtKB:Q8WTW4}.
CC -!- FUNCTION: Suppresses Src-dependent tyrosine phosphorylation and
CC activation of PDPK1 and its downstream signaling. Down-regulates PDPK1
CC kinase activity by interfering with tyrosine phosphorylation at 'Tyr-
CC 9', 'Tyr-373' and 'Tyr-376' residues. May act as a tumor suppressor.
CC Suppresses cell growth and enhances sensitivity to various anticancer
CC drugs. {ECO:0000250|UniProtKB:Q8WTW4}.
CC -!- SUBUNIT: Forms a heterodimer with NPRL3. Interacts with PDPK1 (By
CC similarity). Within the GATOR complex, component of the GATOR1
CC subcomplex, made of DEPDC5, NPRL2 and NPRL3. GATOR1 mediates the strong
CC interaction of the GATOR complex with RRAGA/RRAGC and RRAGB/RRAGC
CC heterodimers (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Lysosome membrane {ECO:0000250|UniProtKB:Q8WTW4}.
CC Note=Localization to lysosomes is amino acid-independent.
CC {ECO:0000250|UniProtKB:Q8WTW4}.
CC -!- SIMILARITY: Belongs to the NPR2 family. {ECO:0000305}.
