Post-Translational Regulation
Captions available
The idea
Post-translational regulation modifies a finished protein's activity or tags it for degradation, acting only after translation has already produced it.
In practice
A ubiquitin tag marks a finished protein for degradation by the proteasome, ending its activity without touching the mRNA that made it.
Where people slip
Post-translational regulation acts at the opposite end from Bio 1333's translational regulation — after a protein exists, not before.
