Functioni

Guanine nucleotide-binding protein forming heterodimeric Rag complexes required for the amino acid-induced relocalization of mTORC1 to the lysosomes and its subsequent activation by the GTPase RHEB. This is a crucial step in the activation of the TOR signaling cascade by amino acids.2 Publications

Interactioni

Subunit structurei

Forms a heterodimer with RRAGA, in a sequence-independent manner, and RRAGB. Heterodimerization stabilizes proteins of the heterodimer. In complex with RRAGA or RRAGB, interacts with RPTOR; this interaction is particularly efficient with GTP-loaded RRAGB and GDP-loaded RRAGC. Interacts with NOL8. Interacts with SH3BP4; the interaction with this negative regulator is most probably direct, preferentially occurs with the inactive GDP-bound form of RRAGB, is negatively regulated by amino acids and prevents interaction with RPTOR (PubMed:11073942, PubMed:14660641, PubMed:18497260, PubMed:22575674). The Rag heterodimer interacts with SLC38A9; the probable amino acid sensor (PubMed:25561175, PubMed:25567906). Interacts with SESN1, SESN2 AND SESN3 (PubMed:25259925).7 Publications
