General annotation (Comments)

Function

Involved in cell growth. Activates CDK2, a kinase involved in the control of the cell cycle, by phosphorylating residue 'Thr-160' By similarity. Required for high-level Shh responses in the developing neural tube. Together with TBC1D32, controls the structure of the primary cilium by coordinating assembly of the ciliary membrane and axoneme, allowing GLI2 to be properly activated in response to SHH signaling. Ref.4

Catalytic activity

ATP + a protein = ADP + a phosphoprotein.

Subunit structure

Monomer By similarity. Interacts with MAK By similarity. Interacts with TBC1D32. Ref.4

Subcellular location

Nucleus. Cytoplasm. Cell projectioncilium Ref.4.

Sequence similarities

Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. CDC2/CDKX subfamily.

Contains 1 protein kinase domain.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: Q9JHU3-1)

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: Q9JHU3-2)

Also known as: Cardiac CCRK;

The sequence of this isoform differs from the canonical sequence as follows:
     168-243: WYRAPELLYG...LPDYNKISFK → SSLSCRTTTR...IHLSCRFLSV
     244-346: Missing.
