Gene Information

human ... TTBK1(84630)

General description

Tau tubulin kinase 1 (TTBK1) is a serine/threonine and tyrosine kinase. It belongs to the casein kinase 1 superfamily and is neuron-specific. The encoded protein has a kinase domain, a unique polyglutamate domain and several PEST (proline–glutamate–serine–threonine) sequences. The gene encoding TTBK1 is localized on human chromosome 6p21.1.

Immunogen

TTBK1 antibody was raised against a 16 amino acid peptide near the carboxy terminus of human TTBK1.

Application

Anti-TTBK1 antibody produced in rabbit has been used in western blotting.

Biochem/physiol Actions

Tau tubulin kinase 1 (TTBK1) is responsible for phosphorylation of TDP-43 (TAR DNA binding protein), a protein associated with amyotrophic lateral sclerosis and frontotemporal lobar dementia. High expression or abundance of TTBK1 might be associated with neurodegeneration in these diseases. It also phosphorylates tau protein and might be associated with Alzheimer′s disease progression.

Target description

Tau tubulin kinase (TTBK1) belongs to the casein kinase 1 superfamily and is involved in the phosphorylation of specific serine/threonine residues in paired helical filaments of the tau protein. It is specifically expressed in the brain and induces tau aggregation in human neuronal cells in a dose-dependent manner. TTBK1 levels have been found to be upregulated in the brains of Alzheimer′s disease (AD) patients, and mice expressing human TTBK1 protein showed significant age-dependent memory impairment. These mice displayed increased levels of the CDK5 activators p25 and p35, and reduced levels of the NMDA receptor types 2B and 2D, suggesting that TTBK1 may play a role in memory dysfunction in AD patients. Multiple isoforms of TTBK1 are known to exist. This antibody is predicted to not cross-react with TTBK2.

Linkage

The action of this antibody can be blocked using blocking peptide SBP3500002.

Physical form

Pathological aggregates of phosphorylated TDP-43 characterize amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD-TDP), two devastating groups of neurodegenerative disease. Kinase hyperactivity may be a consistent feature of ALS and FTLD-TDP, as phosphorylated TDP-43 is not observed in the
