question: Which are the main components of mTORC1?
answer: The mTOR (mammalian target of rapamycin) protein kinase is an important regulator of cell growth and is a key target for therapeutic intervention in cancer. Two complexes of mTOR have been identified: complex 1 (mTORC1), consisting of mTOR, Raptor (regulatory associated protein of mTOR) and mLST8 (mammalian lethal with SEC13 protein 8) and complex 2 (mTORC2) consisting of mTOR, Rictor (rapamycin-insensitive companion of mTOR), Sin1 (stress-activated protein kinase-interacting protein 1), and mLST8.
