Casein kinase I isoform epsilon is an enzyme that in humans is encoded by the CSNK1E gene.[5][6]
Function
editThe protein encoded by this gene is a serine/threonine protein kinase and a member of the casein kinase I protein family, whose members have been implicated in the control of cytoplasmic and nuclear processes, including DNA replication and repair. The encoded protein is found in the cytoplasm as a monomer and can phosphorylate a variety of proteins, including itself. This protein has been shown to phosphorylate proteins of the Period family of circadian rhythm proteins. A homolog of this mammalian protein can be found in Drosophila melanogaster. Known as doubletime, this protein also plays a role in the phosphorylation of proteins involved in circadian rhythms. Two transcript variants encoding the same protein have been found for this gene.[7]
Interactions
editCSNK1E has been shown to interact with PER1[8] and AXIN1.[9]
Inhibitors

- Non-selective
- PF-670462 (also inhibits CK1-δ)
