Multi-Color Single-Molecule Imaging Uncovers Extensive Heterogeneity in mRNA Decoding
mRNA translation is a key step in decoding genetic information. Genetic decoding is surprisingly heterogeneous because multiple distinct polypeptides can be synthesized from a single mRNA sequence.
We find that start site selection is largely stochastic but that the probability of using a particular start site differs among mRNA molecules and can be dynamically regulated over time. This study provides key insights into translation start site selection heterogeneity and provides a powerful toolbox to visualize complex translation dynamics.
more recent work has shown that translation of many if not most mRNAs is far more complex and that different regions of an mRNA can be translated.
