Cyclin-dependent kinase 19 is an enzyme that in humans is encoded by the CDK19 gene.^[5]^[6]^[7]

Inhibitors

The natural product cortistatin A is a potent and selective inhibitor of CDK8 and CDK19.^[8]

Romaciclib is a dual CDK8 and CDK19 inhibitor which is being developed for the treatment of acute myeloid leukaemia (AML).^[9]^[10]^[11]
