Abstract
En 中文
• CDK1 phosphorylates the m6A methyltransferase METTL3 at Ser43 upon mitotic entry • METTL3 phosphorylation allows 7SK methylation and P-TEFb release for transcription • METTL3 phosphorylation is required for timely mitotic exit and chromosome segregation • CDK1-METTL3-7SK-P-TEFb axis integrates RNA methylation into mitotic progression
