Sentences with phrase «initiation factor 4e»

mTORC1 is the central component of the insulin - signaling cascade [insulin / insulin - like growth factor (IGF)-- phosphatidylinositol 3 - kinase (PI3K) pathway)(Fig. 1) that regulates protein synthesis and mRNA translation through 2 primary mechanisms: 1) inactivation of the repressor of mRNA translation, eukaryotic translation initiation factor 4E - binding protein 1 (eIF4E - BP1), and 2) the activation of 70 - kDa ribosomal protein S6 kinase.

They showed genetically that there was an additional response coming from the transcription factor — Forkhead box O (Foxo)-- which in turn enhances the transcription of one of the translational regulators: eukaryotic initiation factor 4E binding protein (4E - BP).

Here, we provide evidence that mTOR signaling phosphoproteins, including mTOR, eukaryotic initiation factor 4E — binding protein - 1, p70S6K, and ribosomal protein S6, are highly phosphorylated in ALK + ALCL cell lines and tumors.

BDNF induces translocation of initiation factor 4E to mRNA granules: evidence for a role of synaptic microfilaments and integrins.

Until now, this initiation protein was thought to be eIF4E (eukaryotic initiation factor 4E) for all mRNAs.

Not exact matches

The translation initiation factor, eIF4E, is an indirect target of mTOR because it is released by phosphorylation of its repressor 4E - BP1 by mTOR - raptor complex, thereby stimulating cap - dependent translation (7, 11, 12).
