Question

Quizplus · Accepted Answer

Ubiquitin is a protein modifier that is primarily involved in the regulation of protein longevity. It marks proteins for degradation by the proteasome, thereby controlling their half-life and turnover rate. This process is important for maintaining cellular homeostasis and preventing the accumulation of damaged or misfolded proteins. Ubiquitin-mediated degradation of specific proteins is also involved in various cellular processes, including cell cycle regulation, DNA repair, and immune response.
