RRAGC

This gene encodes a member of the GTR/RAG GTP-binding protein family. The encoded protein is a monomeric guanine nucleotide-binding protein which forms a heterodimer with RRAGA and RRAGB and is primarily localized to the cytoplasm. The encoded protein promotes intracellular localization of the mTOR complex. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2012]

Ras Related GTP Binding C

Guanine nucleotide-binding protein that plays a crucial role in the cellular response to amino acid availability through regulation of the mTORC1 signaling cascade (PubMed:20381137, PubMed:27234373, PubMed:24095279).
Forms heterodimeric Rag complexes with RRAGA or RRAGB and cycles between an inactive GTP-bound and an active GDP-bound form (PubMed:24095279).
In its active form participates in the relocalization of mTORC1 to the lysosomes and its subsequent activation by the GTPase RHEB (PubMed:20381137, PubMed:27234373, PubMed:24095279).
This is a crucial step in the activation of the TOR signaling cascade by amino acids (PubMed:20381137, PubMed:27234373, PubMed:24095279).

Predominantly cytoplasmic. May shuttle between the cytoplasm and nucleus, depending on the bound nucleotide state of associated RRAGA (PubMed:11073942).

RRAGC mutations have been found in a patient with idiopathic dilated cardiomyopathy with ventricular dilation and systolic dysfunction, bilateral cataracts, and mild facial dysmorphisms.
