Research Backgrounds


Casein kinases are operationally defined by their preferential utilization of acidic proteins such as caseins as substrates. It can phosphorylate a large number of proteins. Participates in Wnt signaling. Phosphorylates CTNNB1 at 'Ser-45'. May phosphorylate PER1 and PER2. May play a role in segregating chromosomes during mitosis. May play a role in keratin cytoskeleton disassembly and thereby, it may regulate epithelial cell migration.

Subcellular Location:

Cytoplasm. Cytoplasm>Cytoskeleton>Microtubule organizing center>Centrosome. Chromosome>Centromere>Kinetochore. Nucleus speckle. Cytoplasm>Cytoskeleton>Cilium basal body.
Note: Localizes to the centrosome in interphase cells, and to kinetochore fibers during mitosis. Also recruited to the keratin cytoskeleton (PubMed:23902688).

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
Subunit Structure:

Monomer. Interacts with the Axin complex. Interacts with TUT1, leading to TUT1 phosphorylation. Interacts with FAM83H; recruits CSNK1A1 to keratin filaments.


Belongs to the protein kinase superfamily. CK1 Ser/Thr protein kinase family. Casein kinase I subfamily.
