20966048	First, we found that pr-set7 is phosphorylated at ser 29 (s29) specifically by the cyclin-dependent kinase 1 (cdk1)/cyclinb complex, s29 phosphorylation also functions to stabilize pr-set7 by directly inhibiting its interaction with the anaphase-promoting complex (apc), an e3 ubiquitin ligase.

24746669	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

In particular, CDK1 is responsible for the early phosphorylations on T1209 and S1223, and it promotes additional late phosphorylation events by PLK1 on AMBRA1. Altogether, these phosphorylation events are critical for proper spindle function and orientation. Indeed, phosphorylated AMBRA1 can interact with NUMA1 and is responsible for NUMA1 proper localization at the cell cortex. Moreover, we observe that loss of AMBRA1 leads to PLK1 protein stabilization and to an increase in phospho-NUMA1 levels which, in turn, contributes to spindle orientation defects.

As mentioned, this dephosphorylation occurs by a Cdc25 protein phosphatase. Three Cdc25 family members have been identified to date, A, B and C, the last one being the active one at the onset of mitosis. The activity of Cdc25C itself can be enhanced through phosphorylation by cyclin B-Cdc2 (9, 10). Therefore, activation of cyclin B-Cdc2 has been proposed to result in an autocatalytic feedback loop to ensure rapid activation of these complexes at the G2/M transition

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).
