Literature-anchored findings (GeneRIF, showing 7)

  • Data show that Rheb like-1 protein (RhebL1) rescues mTOR signaling during nutrient withdrawal, and identify critical residues in Rheb and RhebL1 which are required for their efficient activation of mTOR signaling. (PMID:16098514)
  • RHEBL1 is a positive regulator of NF-kappa B-mediated gene transcription. (PMID:16328882)
  • RhebL1 may be impacting the mTOR pathway in a different manner than Rheb1. (PMID:21655954)
  • Findings are unprecedented and indicate that the DHH-RHEBL1 fusion transcript is a novel recurrent feature in the changing landscape of CBFA2T3-GLIS2-positive childhood AML. (PMID:24127550)
  • These results establish CAD as a downstream effector of Rheb and suggest a possible role of Rheb in regulating de novo pyrimidine nucleotide synthesis.(Rheb small GTPases, which consist of Rheb1 and Rheb2 (also known as RhebL1) (PMID:25422319)
  • High RHEBL1 expression is associated with lung cancer. (PMID:28209923)
  • Rheb1 promotes glucose-stimulated insulin secretion in human and mouse beta-cells by upregulating GLUT expression. (PMID:34375645)

All UniProt accessions (3): C9JQQ1, Q8TAI7, F8W1T5

UniProt curated annotations — full annotation on UniProt →

Function. Binds GTP and exhibits intrinsic GTPase activity. May activate NF-kappa-B-mediated gene transcription. Promotes signal transduction through MTOR, activates RPS6KB1, and is a downstream target of the small GTPase-activating proteins TSC1 and TSC2.

Subunit / interactions. Interacts with MTOR.

Subcellular location. Endomembrane system. Cytoplasm.

Tissue specificity. Ubiquitously expressed. Expression increased at least 2-fold in several tumor cell lines.

Miscellaneous. May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay.

Similarity. Belongs to the small GTPase superfamily. Rheb family.
