Rheb GTPase

Meaning

Rheb GTPase, which stands for Ras homolog enriched in brain, is a small G-protein enzyme that functions as a critical upstream activator of the mechanistic Target of Rapamycin (mTOR) signaling pathway. In the context of hormonal health, this protein is a key metabolic sensor that integrates signals from growth factors, nutrients, and hormones to regulate fundamental cellular processes. Its activity is essential for controlling cell growth, proliferation, and protein synthesis throughout the body.
