Abstract:
The ability of a cell to properly express its genes depends on optimal transcription and splicing. RNA polymerase II (RNAPII) transcribes protein-coding genes and produces pre-mRNAs, which undergo, largely co-transcriptionally, intron excision by the spliceosome complex. Spliceosome activation is a major control step, leading to a catalytically active complex. Recent work has showed that cyclin-dependent kinase (CDK)11 regulates spliceosome activation via the phosphorylation of SF3B1, a core spliceosome component. Thus, CDK11 arises as a major coordinator of gene expression in metazoans due to its role in the rate-limiting step of pre-mRNA splicing. This review outlines the evolution of CDK11 and SF3B1 and their emerging roles in splicing regulation. It also discusses how CDK11 and its inhibition affect transcription and cell cycle progression.

M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
