Question

Quizplus · Accepted Answer

Ubiquitination is a covalent modification of proteins where ubiquitin, a small protein, is attached to the protein being modified. This modification commonly targets the protein for degradation via the proteasome. Therefore, if a protein is covalently modified by ubiquitin, it will likely be degraded.
