Anti-phospho-PRAS40 (Thr246) (Proline-Rich AKT substrate) Antibody

PRAS40 (Proline Rich Akt Substrate, 40 kDa), also known as AKT1S1, is a ubiquitously express protein that is phosphorylated on residue Thr246 via the PI3K/Akt pathway. It was originally discovered as an Akt substrate as it has the putative Akt phosphorylation motif of RxRxxpS/pT2. This phosphorylation allows it to bind 14-3-3 and Raptor of the mTOR complex mTORC1. PRAS40 is known to bind to and regulate mTORC1 (mTOR, Raptor, mLST8) kinases activity that is activated by insulin downstream of PI3K and Akt and subsequently phosphorylates p70S6K and 4EBP1. PRAS40 is known to have a putative TOS motif (FVMDE) that allows it bind to Raptor of mTORC1 in the absence of insulin1. It is thought that through it binding to the Raptor, PRAS40 inhibits the kinase activity of mTORC1 by preventing to bind to its substrates such as p70S6K and 4EBP1.
