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 By similarity.
Catalytic activity	ATP + a protein = ADP + a phosphoprotein.
Subunit structure	Monomer By similarity.
Subcellular location	Cytoplasm.
Post-translational modification	Autophosphorylated By similarity.
Miscellaneous	Triazolodiamine 1 is a commercial name for 5-amino-3-([4-(aminosulfonyl)phenyl]amino)-N-(2,6-difluorophenyl)-1H-1,2,4-triazole-1-carbothioamide.
Sequence similarities	Belongs to the protein kinase superfamily. CK1 Ser/Thr protein kinase family. Casein kinase I subfamily. Contains 1 protein kinase domain.

This entry describes 3 isoforms produced by alternative splicing. [Align] [Select]

Isoform 1 (identifier: Q9Y6M4-1)

Also known as: 3;

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.

Isoform 2 (identifier: Q9Y6M4-2)

Also known as: 3L; CSNK1G3L;

The sequence of this isoform differs from the canonical sequence as follows:
     430-430: K → NCQKVLNMW

Isoform 3 (identifier: Q9Y6M4-3)

The sequence of this isoform differs from the canonical sequence as follows:
     363-394: Missing.
     430-430: K → NCQKVLNMW
