RHEB Recombinant Monoclonal Antibody

Uniprot Id

Q15382

Target Species

Human

Target Name

RHEB

Target Full Name

GTP-binding protein Rheb

Target Function

Activates the protein kinase activity of mTORC1, and thereby plays a role in the regulation of apoptosis. Stimulates the phosphorylation of S6K1 and EIF4EBP1 through activation of mTORC1 signaling. Has low intrinsic GTPase activity.

Target Subcellular Location

Endomembrane system; Lipid-anchor; Cytoplasmic side. Golgi apparatus membrane; Lipid-anchor; Cytoplasmic side. Cytoplasm, cytosol. Endoplasmic reticulum membrane; Lipid-anchor; Cytoplasmic side.

Target Protein Families

Small GTPase superfamily, Rheb family

Target Tissue Specificity

Ubiquitous. Highest levels observed in skeletal and cardiac muscle.

Target Synonyms

Target Background

This gene is a member of the small GTPase superfamily and encodes a lipid-anchored, cell membrane protein with five repeats of the RAS-related GTP-binding region. This protein is vital in regulation of growth and cell cycle progression due to its role in the insulin/TOR/S6K signaling pathway. The protein has GTPase activity and shuttles between a GDP-bound form and a GTP-bound form, and farnesylation of the protein is required for this activity. Three pseudogenes have been mapped, two on chromosome 10 and one on chromosome 22.
