Description

The mammalian target of rapamycin (mTOR) is a conserved Ser/Thr kinase that forms two functionally distinct complexes, mTROC1 and mTORC2, important for nutrient and growth-factor signalling. Rictor (rapamycin-insensitive companion of mTOR) is a component of mTORC2
[2]
. There is a regulatory link between the two mTOR complexes, whereby Rictor phosphorylation by mTORC1 regulates mTORC2 signalling
[1]
. Over-expression of Rictor increases mTORC2 activity and promotes cell growth and motility
[3]
.

This domain is the N-terminal conserved section that may include several individual domains.
