Degradation of misfolded proteins in neurodegenerative diseases: therapeutic targets and strategies

Ciechanover A, Kwon YT

Mammalian cells remove misfolded proteins using various proteolytic systems, including the ubiquitin (Ub)-proteasome system (UPS), chaperone mediated autophagy (CMA) and macroautophagy. The majority of misfolded proteins are degraded by the...
