title: Phosphatase 2A puts the brakes on mTORC1 nutrient signaling.
abstract: Nutrients such as amino acids (aa) and glucose mediate mammalian target of rapamycin complex 1 (mTORC1) signaling to control cell growth and metabolism. Recent studies (Yan et al., 2010) identify a contributor, PP2A phosphatase subunit PR61varepsilon, in regulating the aa-sensitive input to mTORC1.
