Here, we show that a fraction of cyclin B1/Cdk1 proteins localizes to the matrix of mitochondria and phosphorylates a cluster of mitochondrial proteins, including the complex I (CI) subunits in the respiratory chain. Cyclin B1/Cdk1-mediated CI phosphorylation enhances CI activity, whereas deficiency of such phosphorylation in each of the relevant CI subunits results in impairment of CI function.|These results were confirmed by generating phosphorylation defective forms of the five CI subunits through substitutions of S/T residues with Alanine (A) on either Cdk1 optimal or minimal consensus motifs (T383 on NDUFV1, S105 on NDUFV3, S364 on NDUFS2, S55/S29/T5 on NDUFB6, and T142/T120 on NDUFA12). The mutation of Cdk1 consensus motifs severely diminished their phosphorylation |

Thus, we now know the complete mammalian cI structure [22,23] and how the subunits are organized in six modules (N, Q, ND1, ND2, ND4 and ND5)The N-module, which is the tip of the hydrophilic arm and the last one to be incorporated [30,35], results from the assembly of NDUFV1, NDUFV2, NDUFS1 and NDUFA2 [34], to which NDUFA6, NDUFA7, NDUFA12, NDUFS4, NDUFS6 and NDUFV3 must be further associated with to complete the module [24]. |
