Regulating Protein Function

What is ubiquitin’s role in regulation?

Tags proteins with polyubiquitin for degradation.

Where are ubiquitinated proteins degraded?

In the proteasome.

What is allosteric regulation?

Reversible on/off switching of protein activity via conformational change.

What is compartmentalization in regulation?

Controlling protein function by localizing proteins in specific cell regions.

What covalent modification commonly regulates proteins?

Phosphorylation.
