Protein Structure
UniProt Annotation
Function As a component of the GATOR1 complex, inhibitor of the amino acid-sensing branch of the TORC1 pathway. The GATOR1 complex strongly increases GTP hydrolysis by RRAGA and RRAGB within RRAGC- containing heterodimers, thereby deactivating RRAGs, releasing mTORC1 from lysosomal surface and inhibiting mTORC1 signaling. {ECO:0000269PubMed:23723238}.
Subcellular Localization
Disease Associations Note=Inactivating mutations and truncating deletions in the genes encoding GATOR1 proteins are detected in glioblastoma and ovarian tumors and are associated with loss of heterozygosity events. Inactivation of GATOR1 proteins promotes constitutive localization of mTORC1 to the lysosomal membrane and blocks mTORC1 inactivation following amino acid withdrawal (PubMed:23723238). {ECO:0000269PubMed:23723238}.
Tissue Specificity Widely expressed.
