Molecular mechanisms of eukaryotic translational control

NIH Pandemic-Era Grants · Pandemic Era Grants / 2024

Sarah Elizabeth Walker · STATE UNIVERSITY OF NEW YORK AT BUFFALO · 2024 · $333,399 — SUMMARY: The level of each protein synthesized in a cell results from both the amount of mRNA available, and the number of ribosomes that initiate translation of that mRNA. Eukaryotic translation initiation factors (eIFs) can reprogram which mRNAs are available and translated to produce different le…
