"Akt-1 is also phosphorylated at S473 by the mammalian target of Rapamycin (mTOR) complex referred to as (Rapamycin-insensitive companion of mTOR and mLST8 complex) mTORC2 [XREF_BIBR - XREF_BIBR]."

"Two phosphorylation events are necessary for maximal activation of Akt, namely phosphorylation at Thr308 and Ser473 in Akt1 (Thr309/Ser474 in Akt2 and Thr305/Ser472 in Akt3) by phosphoinositide-dependent protein kinase 1 (PDK1) and the mechanistic target of rapamycin (mTOR) complex 2 (mTORC2), respectively [ xref , xref ]."

"Akt1 is phosphorylated by PDK1 at T308, and additionally at S473 by the Pl3K related kinases, mammalian target of rapamycin complex 2 (mTORC2) or DNA-PK to achieve its full kinase activity, depending on the stimulus and the cellular context."

"Upon activation, PIP3 binds to the PH domain, causing conformational changes and exposing Thr309 of AKT1 for phosphorylation of the kinase domain, followed by a secondary phosphorylation of AKT1 at the C-terminal Ser473, which is mediated by the mTOR complex 2 (mTORC2)."

"The Ser 473 phosphorylation of Akt1 by the mechanistic target of rapamycin complex 2 (mTORC2) is controlled by PI3 kinase activation in cells treated with growth factors [ xref , xref ]; however, studies have yet to elucidate the mechanism by which m TORC2 kinase is recruited to the signaling complex containing Akt."

"It is very difficult to define clearly the hierarchy between RhebL1 and AKT1 since mTOR is a downstream effector of Rheb1 or RhebL1 and mTOR phosphorylates S473 of AKT1, leading to fully active form of AKT1 [33, 49]."

"Mammalian TOR complex 1 (mTORC1) and mTORC2 exert their actions by regulating other important kinases, such as S6 kinase (S6K) and Akt.Recent findings have revealed novel important roles for mTORC2 in the phosphorylation of AGC kinase family members. mTORC2 phosphorylates and activates Akt, SGK, and PKC, which regulate cell survival, cell cycle progression and anabolism"

"Protein kinase B (PKB, Akt) is a Ser/Thr kinase involved in the regulation of cell survival, proliferation, and metabolism and is activated by dual phosphorylation on Thr(308) in the activation loop and Ser(473) in the hydrophobic motif. It plays a contributory role to platelet function, although little is known about its regulation. In this study, we investigated the role of the mammalian target of rapamycin complex (mTORC)-2 in Akt regulation using the recently identified small molecule ATP competitive mTOR inhibitors PP242 and Torin1."
