RNF167 activates mTORC1 and promotes tumorigenesis by targeting CASTOR1 for ubiquitination and degradation

CASTOR1 is an arginine sensor that inhibits mTORC1 activation, for which this pathway is frequently dysregulated in cancers. Here the authors show that AKT and E3 ubiquitin ligase RNF167 mediate CASTOR1 phosphorylation and degradation to activate mTORC1 and promote tumorigenesis.
