1 RESULTS: 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 the mTOR/raptor complex, and for 4E-BP1 to be phosphorylated in vivo at all identified mTOR-regulated sites. tos regulatory associated protein of MTOR complex 1 Homo sapiens

3 CONCLUSIONS: Our data demonstrate that the TOS motif functions as a docking site for the mTOR/raptor complex, which is required for multisite phosphorylation of 4E-BP1, eIF4E release from 4E-BP1, and cell growth. tos regulatory associated protein of MTOR complex 1 Homo sapiens
