背景信息

**Background of tTBK2 Recombinant Protein**

Tau tubulin kinase 2 (TTBK2) is a serine/threonine kinase encoded by the *TTBK2* gene, primarily known for its role in regulating cellular processes such as ciliogenesis, microtubule dynamics, and neurodegenerative pathways. It is enzymatically active in phosphorylating tau and tubulin proteins, which are critical for maintaining neuronal structure and function. Dysregulation of TTBK2 has been implicated in neurodegenerative disorders, including Alzheimer’s disease and spinocerebellar ataxia type 11 (SCA11), where mutations in *TTBK2* disrupt kinase activity or protein stability.

The recombinant tTBK2 protein is engineered through molecular cloning and expression systems (e.g., *E. coli* or mammalian cells) to produce a purified, functional form of the kinase for research. This recombinant version often includes tags (e.g., His-tag) for efficient purification and detection. Researchers utilize tTBK2 to study its enzymatic mechanisms, substrate specificity, and interactions with partners like tau or components of the cilium assembly pathway.

Notably, tTBK2 is essential for initiating primary cilia disassembly by phosphorylating substrates that destabilize the ciliary base. Its role in tau phosphorylation also links it to tauopathies, making it a target for therapeutic strategies aimed at modulating kinase activity. Structural studies of recombinant tTBK2 have provided insights into its ATP-binding pocket and regulatory domains, facilitating drug discovery efforts.

Overall, tTBK2 recombinant protein serves as a vital tool for deciphering its biological functions, pathological contributions, and potential as a biomarker or drug target in neurodegenerative and ciliopathy-related diseases.
