CSNK1E

Casein kinase I isoform epsilon is an is_associated_with::enzyme that in humans is encoded by the CSNK1E is_associated_with::gene.

Function
The protein encoded by this gene is a is_associated_with::serine/threonine protein kinase and a member of the casein kinase I protein family, whose members have been implicated in the control of is_associated_with::cytoplasmic and nuclear processes, including is_associated_with::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 is_associated_with::circadian rhythm proteins. A is_associated_with::homolog of this mammalian protein can be found in is_associated_with::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.

Interactions
CSNK1E has been shown to interact with is_associated_with::PER1 and is_associated_with::AXIN1.
