Two dynamically competing factors determine the translation start site
To start, or not to start, that is the recurring question faced by eukaryotic ribosomes as they scan mRNA for translation start sites. A study now shows that two opposing initiation factors, which bind the ribosome in a mutually exclusive manner, assist in this decision-making process.
