"RAFT1 phosphorylation of 4E-BP1 on Thr 36 and Thr 45 blocks its association with the cap binding protein, eIF-4E, in vitro, and phosphorylation of Thr 45 seems to be the major regulator of the 4E-BP1-eIF-4E interaction in vivo."

"MTOR readily phosphorylated T36 PHAS-I and T45 PHAS-I under conditions in which S64 PHAS-I, T69 PHAS-I, and S82 PHAS-I were not significantly phosphorylated."

"Mtorc1 promotes protein synthesis by phosphorylating the eukaryotic initiation factor 4e (eif4e)- binding protein 1 (4e-bp1) and the p70 ribosomal s6 kinase 1 (s6k1). Raft1 phosphorylation of 4e-bp1 on thr-36 and thr-45 blocks its association with the cap-binding protein, eif-4e,in vitro. in response to insulin and nutrients, mtorc1, consisting of mtor, raptor (regulatory-associated protein of mtor), and mlst8, is activated and phosphorylates eukaryotic initiation factor 4e-binding protein (4ebp) and p70 s6 kinase to promote protein synthesis and cell size."

"mTAb1-activated mTOR phosphorylated Thr36, Thr45, Ser64, Thr69, and Ser82 in PHAS-I. All five of these sites fit a (Ser/Thr)-Pro motif and are dephosphorylated in response to rapamycin in rat adipocytes."

"Specifically as part of mTORC1, mTOR directly phosphorylates the ribo- somal protein S6 kinases (S6K1 and S6K2) and the eukaryotic initiation factor 4E (eIF4E)-binding proteins (4E-BP1 and 4E-BP2), both of which control specific steps in the initiation of cap-dependent translation"

"Mutational analysis of sites in the translational regulator, PHAS-I, that are selectively phosphorylated by mTOR. Results obtained with PHAS-I proteins having Ser to Ala mutations in the five known phosphorylation sites indicate that mTOR preferentially phosphorylates Thr36 and Thr45."
