A schematic illustration of the enzymatic reactions is shown in the lower panel. D. Mutations in H149, N152 and D160 abolish the ability of MavQ to convert PtdIns into PtdIns3P.

Figure 3(A) Western blotting analysis depicts mitochondrial proteins (NDUFA9-Complex I, SDHA-Complex II, MTCO1-Complex IV and MTCO2-Complex IV) levels in control derived muscle (n=3), patient derived muscle during the symptomatic phase (n=3) and patient derived muscle after recovery (n=1).

(B) Densitometry analysis of the immunoblotting from (A) showing an increase in SDHA (Complex II), while NDUFA9 (Complex I) probably as a compensatory mechanism and MT-CO2 (Complex IV) show significant reductions as the majority of mitochondrial encoded proteins belong to this two complexes, thus being destabilized by the defective mitochondrial mistranslation.

Acetylation of Cse4 K49 counteracts mutation of Cse4-R37.Figure 5Cse4-K49Ac and -R37Me are increased in S-phase of the cell cycle. Cells carrying 3xHA-tagged Cse4 were used to immunoprecipitate Cse4 with an α-Cse4-K49Ac (left, top) and an α-HA antibody (left, bottom). To detect Cse4-R37 methylation, 3xHA-tagged Cse4 was immunoprecipitated with an α-Cse4-R37Me2a (right, top) (Samel et al., 2012) and an α-HA antibody (right, bottom).
