mTORC2 associates closely with the plasma membrane, and has been detected in association with ribosomal membranes (11), where it can interact with its key substrates, the AGC kinases including AKT1-3, serum glucose kinase (SGK) isoforms, and protein kinase C (PKC) family members.
Rapamycin is a known allosteric inhibitor of mTORC1, while TOR kinase inhibitors (TOR-KIs) inhibit the activities of both complexes.
AKT, a key substrate of mTORC2, is among the most commonly hyper-activated proteins in cancer. AKT integrates signals from PI3K/mTORC2 and from PI3K/PDK1 to promote cell growth and survival.
