4E-BP1

Gene/Protein · 7 studies in the Atlas · also known as 4E-BP, 4EBP1, EIF4EBP1, PHAS-I

Translational repressor; the master effector through which mTORC1 controls protein synthesis. mTORC1 phosphorylates 4E-BP1 to release eIF4E and switch translation ON.

SCH20252025BFirst-in-human trial of a bi-steric mTORC1-selective inhibitor. Treatment-related hyperglycemia was low (4%) and not dose-limiting -- direct clinical confirmation that sparing mTORC2 avoids the metabo
MEN20232023CRMC-6272, a bi-steric molecule with >25-fold selectivity for mTORC1 over mTORC2, completely suppresses mTORC1 (hitting the rapamycin-resistant substrate 4E-BP1) and overcomes hormone- and CDK4/6-inhib
ZID20092009CConnected the dots between diet, mTOR, and lifespan. Dietary restriction lowers mTOR activity, which frees up 4E-BP - and here 4E-BP was shown to be REQUIRED for the lifespan boost, working by selecti
LAB20152015DExplained HOW rapamycin calms 'inflammaging'. Senescent cells spew inflammatory signals (the SASP) that damage surrounding tissue and even feed tumors. mTOR powers this by translating IL1A, the cytoki
HSI20122012DShowed WHY mTOR-driven translation matters for cancer: in prostate cancer, oncogenic mTOR selectively translates a specific set of pro-invasion mRNAs that drive metastasis. An ATP-competitive mTOR inh
THO20122012DUsed ribosome profiling with the complete inhibitor Torin1 to settle a long debate: mTORC1's translational control runs almost entirely through the 4E-BP family acting on a specific class of mRNAs (TO
THO20092009DDropped a bombshell: rapamycin does NOT fully block mTORC1. Using Torin1 (which jams the active site directly), the authors showed rapamycin leaves important mTORC1 jobs running - notably 4E-BP1 phosp
