Protein attributes

Sequence length	125 AA.
Sequence status	Fragment.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	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 on 'Ser-45' By similarity.
Catalytic activity	ATP + a protein = ADP + a phosphoprotein.
Subunit structure	Monomer. Interacts with the Axin complex By similarity.
Subcellular location	Cytoplasm.
Sequence similarities	Belongs to the protein kinase superfamily. CK1 Ser/Thr protein kinase family. Casein kinase I subfamily. Contains 1 protein kinase domain.
