    basic FUNCTION
  • regulating S transition of the cell cycle
  • may play a role in transcriptional regulation
  • important role of cyclin C (CCNC) in regulating human HSPC (hematopoietic stem/progenitor cells) quiescence
    • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • part of CDK8 subcomplex (containing CDK8, cyclin C, MED12, and MED13), functioning as a simple switch that controls the Mediator–pol II interaction to help regulate transcription initiation and reinitiation events (Knuesel 2009)
    • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • interacts with cyclin-dependent kinase 8 and induces the phophorylation of the carboxy-terminal domain of the large subunit of RNA polymerase II
  • partner of cyclin-dependent kinase CDK3, CCNC controls cellular proliferation and, together with CDK8, represses gene transcription
  • CDK8 associates with cyclin C (CCNC) and belongs to the CDK module of the Mediator of transcription, together with MED12 and MED13
  • CDK8 is a regulatory partner of CCNC
  • MTOR is a critical regulator of CDK8 and its activating partner CCNC
  • CDK8 and its paralog CDK19, in complex with CCNC, MED12 and MED13, are transcriptional regulators that mediate several carcinogenic pathways and the chemotherapy-induced tumor-supporting paracrine network
