Abstract:

Casein kinase 1 epsilon (CK1epsilon) and its closest homologue CK1delta are key regulators of diverse cellular processes. We report two crystal structures of PF4800567, a potent and selective inhibitor of CK1epsilon, bound to the kinase domains of human CK1epsilon and CK1delta as well as one apo CK1epsilon crystal structure. These structures provide a molecular basis for the strong and specific inhibitor interactions with CK1epsilon and suggest clues for further development of CK1delta inhibitors.
