CC -!- FUNCTION: Guanine nucleotide-binding protein that plays a crucial role
CC in the cellular response to amino acid availability through regulation
CC of the mTORC1 signaling cascade. Forms heterodimeric Rag complexes with
CC RRAGC or RRAGD and cycles between an inactive GDP-bound and an active
CC GTP-bound form. In its active form participates in the relocalization
CC of mTORC1 to the lysosomes and its subsequent activation by the GTPase
CC RHEB. Involved in the RCC1/Ran-GTPase pathway.
CC {ECO:0000250|UniProtKB:Q5VZM2}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=GTP + H2O = GDP + H(+) + phosphate; Xref=Rhea:RHEA:19669,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:37565,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:58189;
CC Evidence={ECO:0000250|UniProtKB:Q5VZM2};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:19670;
CC Evidence={ECO:0000250|UniProtKB:Q5VZM2};
CC -!- ACTIVITY REGULATION: The activation of GTP-binding proteins is
CC generally mediated by a guanine exchange factor (GEF), while
CC inactivation through hydrolysis of bound GTP is catalyzed by a GTPase
CC activating protein (GAP). The GATOR1 complex functions as a GAP and
CC stimulates RRAGB GTPase activity to turn it into its inactive GDP-bound
CC form. {ECO:0000250|UniProtKB:Q5VZM2}.
CC -!- SUBUNIT: Interacts with RRAGC and RRAGD; heterodimerization stabilizes
CC RRAG proteins (By similarity). In complex with RRAGC, but not with
CC RRAGA, interacts with RPTOR; this interaction is particularly efficient
CC with GTP-loaded RRAGB and GDP-loaded RRAGC (By similarity). Component
CC of the lysosomal folliculin complex (LFC), composed of FLCN, FNIP1 (or
CC FNIP2), RRAGA/RagA or RRAGB/RagB GDP-bound, RRAGC/RagC or RRAGD/RagD
CC GTP-bound, and Ragulator (By similarity). Interacts with SH3BP4; the
CC interaction with this negative regulator is most probably direct,
CC preferentially occurs with the inactive GDP-bound form of RRAGB, is
CC negatively regulated by amino acids and prevents interaction with RPTOR
CC (By similarity). Interacts with the GATOR1 complex; inactivates RRAGB
CC (By similarity). The Rag heterodimer interacts with SLC38A9; the
CC probable amino acid sensor. Interacts with SESN1, SESN2 and SESN3
CC (PubMed:25259925). {ECO:0000250|UniProtKB:Q5VZM2,
CC ECO:0000250|UniProtKB:Q7L523, ECO:0000269|PubMed:25259925}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q5VZM2}.
CC Lysosome {ECO:0000250|UniProtKB:Q5VZM2}.
CC -!- SIMILARITY: Belongs to the GTR/RAG GTP-binding protein family.
CC {ECO:0000305}.
