The kinase is quite distinct from casein kinase 2, which also phosphorylates Ser-111 of 4E-BP1. The possible importance of these kinases in the phosphorylation of 4E-BP1 in fat cells is discussed. It is suggested that the phosphorylation of Ser-111 might be a priming event that facilitates the subsequent phosphorylation of Thr-36, Thr-45, Ser-64 and Thr69 by a rapamycin-sensitive process that initiates the dissociation of 4E-BP1 from eIF4E and hence the formation of the eIF4F complex. |

Here, we show that a functional TOS motif is required for 4E-BP1 to bind to raptor (a recently identified mTOR-interacting protein), for 4E-BP1 to be efficiently phosphorylated in vitro by themTOR/raptor complex, and for 4E-BP1 to be phosphorylated in vivo at all identified mTOR-regulated sites. mTOR/raptor regulated phosphorylation is necessary for 4E-BPs efficient release from the translational initiation factor eIF4E. We find that the TOS motif is absolutely required for efficient phosphorylation of 4E-BP1 at all the identified mTOR-regulated sites, namely, Thr37/46, Ser65, and Thr70 in vivo. |

PHAS-I in adipocytes and HEK293 cells is phosphorylated in the following five sites, all of which conform to a (S/T)P motif (9, 10): Thr-36, Thr-45, Ser-64, Thr-69, and Ser-82. Thr-45 and Ser-64 flank the eIF4E-binding motif (7, 8), and phosphorylation of either site blocks eIF4E binding in vitro (10, 11). Insulin stimulates the phosphorylation of Thr-36, Thr-45, Ser-64, and Thr-69 in both fat cells and HEK293 cells, and incubating cells with rapamycin decreases the phosphorylation of these sites.Immunoprecipitated epitope-tagged mammalian target of rapamycin (mTOR) phosphorylated Thr-36/45. mTOR also phosphorylated Thr-69 and Ser-64 but only when purified immune complexes were incubated with the activating antibody, mTAb1. |

In response to UV-B irradiation, the translation factor 4E-BP1 (eukaryotic initiation factor 4E [eIF4E]-binding protein 1) was phosphorylated at Thr36, Thr45, Ser64 and Thr69. Using either p38 MAPK inhibitors or the MSK inhibitor H89, UV-B-irradiation-induced phosphorylation was blocked [43]. 4E-BP1 binds to eIF4E in resting cells to prevent formation of a functional eIF4F complex, which is essential for cap-dependent initiation of translation. Phosphorylation of 4E-BP1 leads to dissociation from eIF4E |

Here, using mass spectrometry, we identify the serum-responsive, rapamycin-sensitive sites as Ser 65 and Thr 70. | Phosphorylation of Thr 37/Thr 46 is followed by Thr 70 phosphorylation, and Ser 65 is phosphorylated last. Finally, we show that phosphorylation of Ser 65 and Thr 70 alone is insufficient to block binding to eIF4E, indicating that a combination of phosphorylation events is necessary to dissociate 4E-BP1 from eIF4E. |

Phosphorylation of 4e-bp1 is critical in causing its dissociation from eif-4e, leaving 4e available to form translationally active eif-4f complexes, switching on mrna translation. We show that the cyclin-dependent kinase, cdc2, phosphorylates 4e-bp1 at thr-70 and that phosphorylation of this site is permissive for ser-65 phosphorylation. Crucially, the increased phosphorylation of 4e-bp1 during mitosis results in its complete dissociation from eif-4e. |
