"Under physiological conditions, UPS, located in the cytosol and the nucleus in eukaryotic cells, as a major intracellular short-lived protein degradation system (Schwartz and Ciechanover 2009), mediates the clearance of misfolded or other abnormally modified proteins with the help of ubiquitin-activating enzyme (E1), ubiquitin-conjugating enzyme (E2), ubiquitin ligase (E3), and the 26S proteasome for the sake of preventing the accumulation of toxic substances (Shang and Taylor 2011)"
