Function
Component of the Mediator complex, a coactivator involved in regulated gene transcription of nearly all RNA polymerase II-dependent genes. Mediator functions as a bridge to convey information from gene-specific regulatory proteins to the basal RNA polymerase II transcription machinery. Mediator is recruited to promoters by direct interactions with regulatory proteins and serves as a scaffold for the assembly of a functional pre-initiation complex with RNA polymerase II and the general transcription factors. Phosphorylates the CTD (C-terminal domain) of the large subunit of RNA polymerase II (RNAp II), which may inhibit the formation of a transcription initiation complex. Phosphorylates CCNH leading to down-regulation of the TFIIH complex and transcriptional repression. Recruited through interaction with MAML1 to hyperphosphorylate the intracellular domain of NOTCH, leading to its degradation.

- Activity summary
Cdk8 also known as Cyclin-dependent kinase 8 forms an important component of the transcription regulation machinery. It has a molecular mass of about 66 kDa and is widely expressed in various tissues though its abundance can vary. Cdk8 operates largely in the nucleus of cells where it participates in regulating gene expression. Cdk8 acts as a kinase by modifying other proteins through phosphorylation which alters their activity and function.
- Biological function summary
Cdk8 plays a critical role in modulating transcriptional responses. It does this by becoming part of the Mediator complex which is essential for transcription regulation by RNA Polymerase II. The Mediator complex where Cdk8 acts as a kinase influences the initiation and regulation of gene expression. Cdk8 phosphorylates several transcription factors and other components affecting their ability to activate or repress transcription.
- Pathways
Cyclin-dependent kinase 8 functions prominently in the Wnt/β-catenin signaling and Notch signaling pathways both essential for development and cell differentiation. In the Wnt pathway it interacts closely with proteins like β-catenin to influence gene activation. In the Notch pathway it modulates transcription factors related to cellular differentiation processes. These interactions underline its role as a regulator in carefully managing cellular responses to signaling cues.
- Associated diseases and disorders
Cdk8 has been implicated in cancer and congenital disorders. Its overactivity can lead to uncontrolled cell growth contributing to tumor progression notably in colorectal cancer where it affects genes in the Wnt pathway. Beyond cancer its dysfunction links to congenital heart defects where it affects cardiogenesis-associated proteins such as NOTCH1. Cdk8’s involvement in these pathways highlights its part in both regular development and disease pathogenesis.
