Also known as: cdk8; CDK8; CG10572; dCdk8; DmCdk8; Dmel\CG10572; dTRAP56; p58
Summary: Enables protein serine/threonine kinase activity. Involved in several processes, including G1/S transition of mitotic cell cycle; imaginal disc-derived leg segmentation; and sex comb development. Located in nucleus. Part of CKM complex and mediator complex. Is expressed in central brain primordium; organism; and ventral nerve cord primordium. Used to study developmental and epileptic encephalopathy 87. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 87 and dilated cardiomyopathy. Orthologous to human CDK19 (cyclin dependent kinase 19) and CDK8 (cyclin dependent kinase 8). [provided by Alliance of Genome Resources, Dec 2024]

observed biochemical association between Integrator proteins and cyclin C/Cdk8, and that overexpression of a kinase-dead Cdk8 causes snRNA misprocessing
Title: An RNAi screen identifies additional members of the Drosophila Integrator complex and a requirement for cyclin C/Cdk8 in snRNA 3'-end formation.
Data demonstrate that Med12 and Med13 but not CycC or Cdk8 are essential for Serpent/Lozenge-induced transactivation in cell culture.
