Background: Cyclin E-CDK2 is a key protein kinase in the cell cycle. Results: Phosphorylation of PHF8 by cyclin E-CDK2 enhances its demethylase activity toward H3K9me2 and promotes rDNA transcription as well as S phase progression. Conclusion: Cyclin E-CDK2-dependent phosphorylation of PHF8 affects its function. Significance: We unveiled the mechanism of how cyclin E-CDK2 regulates the function of PHF8 in cell cycle regulation.
