Cytoplasmic translational initiation

WebDec 27, 2024 · About 14% of mRNAs are rhythmically translated in WT cells, and translation rhythms for ∼30% of these mRNAs, which we named circadian translation-initiation-controlled genes (cTICs), are dependent on the clock and CPC-3. Most cTICs are expressed from arrhythmic mRNAs and contain a P-body (PB) localization motif in their … WebFeb 24, 2024 · In addition to the localization in nucleus, METTL16 is distributed in the cytoplasm of lung cancer cells, where it interacts with the translation initiation repressor eIF4E2. The cytoplasmic METTL16-eIF4E2 association impedes the recruitment of eIF4E2 to 5′ cap structure, facilitating eIF4E-cap recognition and oncogenic protein synthesis.
