A substantial amount of mitochondrial energy is required for cell cycle progression. However, the mechanisms coordinating the mitochondrial respiration with G2/M transition, a critical step in cell division, remains to be elucidated. Here we show that a fraction of cell cycle CyclinB1/Cdk1 proteins localizes into the matrix of mitochondria and phosphorylates a cluster of mitochondrial proteins including the complex I (CI) subunits in the respiratory chain. The CyclinB1/Cdk1-mediated CI subunit phosphorylation enhances CI activity, whereas deficiency of such phosphorylation in each of the relevant CI subunits results in impairment of CI function. Mitochondria-targeted CyclinB1/Cdk1 increases mitochondrial respiration with enhanced oxygen consumption and ATP generation, which provides cells with efficient bioenergy for G2/M transition and shortens overall cycling time. Thus, CyclinB1/Cdk1-mediated phosphorylation of mitochondrial substrates allows cells to sense and respond to an increased energy demand for G2/M transition, and subsequently to up-regulate mitochondrial respiration for a successful cell cycle progression.
