What are Some Examples of Ubiquitin-Mediated Catalytic Processes?
One notable example is the regulation of the cell cycle by the anaphase-promoting complex/cyclosome (APC/C), an E3 ubiquitin ligase that targets cell cycle proteins for degradation, thus ensuring proper cell cycle progression. Another example is the role of ubiquitin in DNA repair processes, where ubiquitination of histones and other repair proteins modulates their activity and recruitment to sites of DNA damage, facilitating efficient repair.
