Life and destruction: ubiquitin-mediated proteolysis in aging and longevity
The ubiquitin/proteasome system (UPS) regulates the turnover of improperly folded and damaged proteins to maintain protein homeostasis (proteostasis), cellular function, and viability. It is commonly thought that an age-related impairment of the UPS affects general proteostasis networks, which cause...

Sumario: | The ubiquitin/proteasome system (UPS) regulates the turnover of improperly folded and damaged proteins to maintain protein homeostasis (proteostasis), cellular function, and viability. It is commonly thought that an age-related impairment of the UPS affects general proteostasis networks, which causes enhanced protein aggregation and contributes to normal aging. Recent studies identified the existence of ubiquitin-dependent degradation pathways that specifically control lifespan regulators, suggesting additional roles for ubiquitylation in aging and longevity. |
