PRAS40: Lysates

PRAS40 (40 kDa proline-rich Akt1 substrate), also known as AKT1S1, is a widely expressed component of the cytoplasmic mTOR complex (mTORC1). In response to insulin stimulation, Akt1 phosphorylation of PRAS40 relieves the basal PRAS40-mediated inhibition of mTORC1. Activated mTORC1 is a key effector of the cell survival pathway. PRAS40 phosphorylation by Akt3 or Pim1 similarly exerts an anti-apoptotic effect during tumor progression and neuronal ischemia . Alternate splicing generates an isoform that lacks the N-terminal 130 amino acids.
