Translational Regulation
Captions available
The idea
Translational regulation controls how efficiently an mRNA already delivered to the ribosome is actually translated into protein.
In practice
A regulatory protein binding an mRNA's start codon or untranslated region blocks ribosome access, reducing how much protein that mRNA produces.
Where people slip
This level acts on an mRNA that already exists and is otherwise ready — it changes translation efficiency, not the mRNA's sequence or abundance.
