Which of the following types of protein degradation is mediated by the ubiquitin-proteasome pathway and involves the recognition of proteins with abnormal or damaged structures?

A Autophagy
B Proteolysis by lysosomal enzymes
C Proteasomal degradation ✓
D Exoproteolytic degradation

Explanation

The ubiquitin-proteasome pathway is a major protein degradation pathway that recognizes and degrades proteins with abnormal or damaged structures, targeting them for proteasomal degradation.
