Overview
mTOR an atypical kinase belonging to the PIKK family of kinases. Is the catalytic subunit of two protein complexes, mTORC1 and mTORC2. mTORC1 activates S6K and inactivates 4E-BP1, up-regulating protein synthesis. mTORC1 contains Raptor, a positive regulatory subunit and scaffold for recruiting substrates, two negative regulators, PRAS40 and DEPTOR, and mLST8; it is a target for the cell-cycle arrest and immunosuppressive effects of the FKBP12-rapamycin complex. mTORC2, a downstream effector of PI3K, is insensitive to rapamycin and activates Akt by phosphorylating a key activation site. mTORC2 contains regulatory subunits Rictor and mSIN1, PROTOR, mLST8, and the negative regulator DEPTOR. mTORC1 suppresses PI3K activity via a strong negative feedback loop that involves S6K1. Inhibiting mTORC1 ablates this negative feedback loop and potentiates PI3K signaling. Known inhibitors of mTOR include rapamycin, temsirolimus (CCI-779).
