20S Proteasome α5 Activators

20S Proteasome α5 Activators, as identified in this list, are primarily compounds that can influence the function or expression of the 20S Proteasome α5 subunit indirectly. Most of the compounds listed are proteasome inhibitors. While they inhibit proteasome activity, they can also induce compensatory cellular mechanisms that may lead to changes in proteasome composition, expression, or activity.

Proteasome inhibitors like MG132, Bortezomib, Carfilzomib, and Lactacystin are widely used in research. Their primary action is to block proteasome activity, leading to the accumulation of proteins within cells. This accumulation can trigger cellular stress responses and enhance the expression or activity of other components of the proteasome system as a compensatory mechanism. Natural compounds such as Withaferin A, Celastrol, and Curcumin have been shown to modulate various cellular pathways, including those involving the proteasome. Their effects on the proteasome are part of a broader influence on cellular homeostasis and stress responses.
