RHEB - Wikipedia
RHEB also known as Ras homolog enriched in brain (RHEB) is a GTP-binding protein that is ubiquitously expressed in humans and other mammals. The protein is largely involved in the mTOR pathway and the regulation of the cell cycle.
Rheb泛素化调控生长因子诱导的mTORC1激活 - 知乎
研究结论:Rheb泛素化需要TSC复合物的GAP活性,其中TSC2可能主要促进Rheb的单泛素化。另外,Rheb的泛素化与其失活密切相关,而EGF处理会抑制Rheb的泛素化。 2.RNF152是Rheb的E3泛素连接酶. 作者筛选了一组E3连接酶,以确定催化Rheb泛素化的特异性E3连接酶。

RHEB 蛋白, Human (GST) | MCE - MCE-生物活性分子大师
RHEB is an important small GTPase that acts as an allosteric activator of the mTORC1 complex, a key nutrient sensor that controls cell growth and biomass production. In response to signals such as nutrients and growth factors, RHEB activates the MTOR kinase within mTORC1 by inducing conformational changes.
A small molecule inhibitor of Rheb selectively targets mTORC1 ... - Nature
