The proteasome and the degradation of oxidized proteins: Part II – protein oxidation and proteasomal degradation
Abstract Here, we review the role of oxidative protein modification as a signal for recognition and degradation of proteins. It was clearly demonstrated that the ATP- and ubiquitin-independent 20S proteasome is playing a key role in the selective...
