Figure 3: The UBZ domain of Pol η is required for mono-ubiquitination and mono-NEDDylation.

Figure 3:

(A) An AlphaFold generated model of ubiquitin in complex with the c-terminus of Pol η. (B and C) WT or D652A FLAG Pol η was immunoprecipitated from 293T cells co-expressing HA ubiquitin (B) or HA NEDD8 (C). The eluent and lysate were immunoblotted as indicated. Relative mono-UBLylation was calculated based on the ratio of higher to lower FLAG Pol η bands. Mono-ubiquitination and mono-NEDDylation was calculated based on the ratio of HA to FLAG bands. The graph represents calculated values from three independent experiments. Error bars represent standard deviation. Unpaired t-tests were used to assess differences in Pol η modification. * = p < 0.5, ** = p < 0.1, *** = p <0.01.
