AKT1S1 (PRAS40) is phosphorylated by AKT at Thr246, which leads to the binding of YWHAB (14-3-3 beta) (Zhang et al. 2002, Kovacina et al. 2003. AKT1S1 is phosphorylated at Ser183 by mTORC1 (Oshiro et al. 2007); mutation of Ser183 decreases the affinity of AKT1S1 with YWHAB. As AKT1S1 suppresses mTORC1 phosphorylation of S6K1 and 4E-BP1 (Oshiro et al. 2007), binding of YWHAB is proposed to relieve this inhibition (Wang et al. 2012).
