WebThe Cdk8 kinase module (CKM) in Mediator, comprising Med13, Med12, CycC, and Cdk8, regulates RNA polymerase II transcription through kinase-dependent and -independent functions. Numerous pathogenic mutations causative for neurodevelopmental disorders and cancer congregate in CKM subunits. WebFeb 3, 2014 · This suppression effect was attributed largely to the kinase function of Cdk8, as coexpression of kinase-inactive CDK8 (D290A) with MED3 did not abolish FLO11 expression; rather, expression was maintained at ∼40% compared with MED3 alone (Fig. 1B). These data imply that the activation potential of Med3 is suppressed by Cdk8 …

WebJul 3, 2024 · CDK8 is a key subunit of Mediator complex, a large multiprotein complex that is a fundamental part of the conserved eukaryotic transcriptional machinery. However, the biological functions of CDK8 in plant abiotic stress responses remain largely unexplored.
