Substrate-specific degradation is a key feature of the ubiquitin proteasome system. Substrate specificity is typically directed by the E3 or ubiquitin ligase; such specificity can be conferred either by ligase modification or expression or conversely via modification of substrates that permit their recognition by a specific E3 ligase. The most ...
