Subunit of mTORC2, which regulates cell growth and survival in response to hormonal signals.
mTORC2 is activated by growth factors, but, in contrast to mTORC1, seems to be nutrient –
insensitive. mTORC2 seems to function upstream of Rho GTPases to regulate the actin
cytoskeleton, probably by activating one or more Rho-type guanine nucleotide exchange factors.
mTORC2 promotes the serum-induced formation of stress-fibers or F-actin. mTORC2 plays a
critical role in AKT1 ‘Ser-473’ phosphorylation, which may facilitate the phosphorylation of the
activation loop of AKT1 on ‘Thr-308’ by PDK1 which is a prerequisite for full activation.
mTORC2 regulates the phosphorylation of SGK1 at ‘Ser-422’. mTORC2 also modulates the
phosphorylation of PRKCA on ‘Ser-657’. Plays an essential role in embryonic growth and
development
