| Abstract: | Mitochondrial polymerase gamma (PolγA) is the only replicative polymerase in mitochondria. To determine PolγA ubiquitylation in cells, Flag-PolγA and MITOL are overexpressed, and subsequently the immunoprecipitated Flag-PolγA is checked for ubiquitylation. Alternately, in vitro synthesized PolγA and MITOL are used to determine whether PolγA is ubiquitylated. Either anti-ubiquitin or anti-Flag antibody is used to detect the ubiquitylated product. Thus, we provide a detailed, reliable, highly reproducible protocol for detecting ubiquitylation of PolγA by MITOL, both in cells and in vitro. For complete details on the use and execution of this protocol, please refer to Hussain et al. (2021). |
