Ubp3 mediates dynamic deubiquitination of mitochondria upon induction of mitophagy

Ensuring quality and maintenance of mitochondria within eukaryotic cells is important for cellular fitness. One critical pathway that needs to be tightly controlled to achieve this is mitophagy, which is negatively regulated by the deubiquitinase Ubp3 in Saccharomyces cerevisiae. Here we show that beyond this establish...

In vitro characterization of the baker’s yeast deubiquitinase Ubp3

It is indicated that the catalytic domain alone is sufficient for substrate cleavage, whereas the extensive IDRs of Ubp3 and its cofactor Bre5 might contribute to substrate recognition or specificity, which highlights the importance of intrinsically disordered regions in regulating deubiquitinase function and cellular...
