Function
KC1E_HUMAN Casein kinases are operationally defined by their preferential utilization of acidic proteins such as caseins as substrates. Can phosphorylate a large number of proteins. Participates in Wnt signaling. Phosphorylates DVL1. Central component of the circadian clock. In balance with PP1, determines the circadian period length, through the regulation of the speed and rhythmicity of PER1 and PER2 phospohorylation. Controls PER1 and PER2 nuclear transport and degradation. Inhibits cytokine-induced granuloytic differentiation.[1] [2] [3] [4]
Publication Abstract from PubMed
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.
