Cyclin-dependent kinase 7 (Cdk7) is required in cell-cycle and transcriptional regulation. It is regulated by two phosphorylations in the activation segment. Here, the authors report a structure of the human Cdk7/Cyclin H/Mat1 complex containing both phosphorylations, with further insights into the regulatory mechanisms.
