Quizplus · Accepted Answer

A proteasome is a multisubunit protease complex that degrades proteins marked for destruction. It contains several proteolytic enzymes and regulatory subunits that work together to break down unwanted or damaged proteins. It plays a crucial role in maintaining cellular homeostasis and is involved in various cellular processes such as cell cycle regulation, antigen presentation, DNA repair, and apoptosis.
