Products from BPS Bioscience require a minimum order value above 400€
Applications: Study enzyme kinetics and screen small molecule inhibitors for drug discovery and high throughput screening (HTS) applications.
Background: TTBK2, or tau tubulin kinase 2, belongs to the serine-threonine kinase family, involved in primary cilium assembly. Mutations in TTBK2 are responsible for spinocerebellar ataxia 11 (SCA11), which is characterized by loss of Purkinje cells and connection to other neurons in the cerebellum. Loss of TTBK2 in a conditional knockout identified the critical role of this protein in Purkinje cells, where lack of cilia resulted in abnormal intracellular calcium levels and in loss of VGLUT2 positive synapses from dendrites. Studies into the mechanism of action of TTBK2 have identified that mutant protein can interfere with peroxisome numbers and localization, impairing the traffic of SMO (smoothened) to the cilia. Further studies are required to identify the exact functions of this protein and how best to target it when impaired.
Contraindications: The final concentration of DMSO in the assay should not exceed 1%.
Description: The Chemi-Verse™ TTBK2 Kinase Assay Kit is designed to measure TTBK2 (tau tubulin kinase 2) serine-threonine kinase activity for screening and profiling applications using ADP-Glo™ as a detection reagent. The assay kit comes in a convenient 96-well format, with enough purified recombinant TTBK2 kinase, kinase substrate, ATP, and kinase assay buffer for 100 enzyme reactions.
Storage Stability: This assay kit will perform optimally for up to 6 months from date of receipt when the materials are stored as directed.
