Abstract:

Casein kinase 1 delta (CK1delta) and its closest homologue CK1epsilon are key regulators of diverse cellular growth and survival processes such as Wnt signaling, DNA repair, and circadian rhythms. We report three crystal structures of the kinase domain of human CK1delta, one apo and two complexed with a potent and selective CK1delta/epsilon inhibitor PF670462 in two different crystal forms. These structures provide a molecular basis for the strong and specific inhibitor interactions and suggest clues for further development of CK1delta/epsilon inhibitors.
