R. et al. The proteasome is a major proteolytic machine that regulates cellular proteostasis through selective degradation of ubiquitylated proteins1,2. Moreover, emerging evidence suggests that the proteasome plays an important role in various intractable diseases that have been increasing in today’s aging society.Copyright 2019 Nobelprizemedicine.org | All Rights Reserved |,The Nobel Prizes in the field of neuroscience,Karolinska Research Lectures – Keiji Tanaka.
