Question

Quizplus · Accepted Answer

A proteasome is a multisubunit protease complex that degrades proteins marked for destruction. It is responsible for the non-lysosomal degradation of intracellular proteins involved in various cellular processes, including cell cycle progression, signal transduction, and gene expression. The proteasome is composed of multiple subunits that work together to recognize, unfold, and degrade the targeted proteins.
