25733682	MEF2C and MEF2D interact with the E3 ligase F-box protein SKP2, which mediates their subsequent degradation through the ubiquitin-proteasome system. The cyclin-dependent kinase 4 (CDK4)/cyclin D1 complex phosphorylates MEF2D on serine residues 98 and 110, and phosphorylation of these residues is an important determinant for SKP2 binding.

18079698	We investigated the ability of four active CDK/cyclin pairs to phosphorylate UNG2 in vitro.When UNG2 was subjected to in vitro phosphorylation by either of these sets of CDK/cyclins, multiple phosphorylated forms of UNG2 were observed (Figure 5B). Mass spectrometry analyses revealed that the ‘early' CDK4/cyclin D and CDK2/cyclin E kinases were able to phosphorylate all three UNG2 Ser/Thr residues observed in vivo (only CDK2/cyclin E shown). Of these, only S64 was phosphorylated by the ‘late' CDK2/cyclin A and CDK1/cyclin B kinases.Mass spectrometry analyses revealed that the ‘early' CDK4/cyclin D and CDK2/cyclin E kinases were able to phosphorylate all three UNG2 Ser/Thr residues observed in vivo (only CDK2/cyclin E shown). Of these, only S64 was phosphorylated by the ‘late' CDK2/cyclin A and CDK1/cyclin B kinases (Figure 5B, upper panels) in agreement with the accumulation of this phosphorylation in G2 (Figure 3B). In addition, (unspecific) phosphorylation by all kinases was observed at S12 and S14.
