TTBK2: A Potential Drug Target and Biomarker for the Treatment of Neurological Disorders

Introduction

Neurological disorders are a significant public health issue, affecting millions of people worldwide. These disorders often result from the loss of function of neurons, which can lead to significant functional impairments. One of the underlying causes of many neurological disorders is the dysfunction of the microtubules, which are essential structures that support the movement of neurons and play a crucial role in the regulation of various cellular processes. The tau protein, which is a key component of microtubules, has been implicated in the development and progression of numerous neurological disorders. Therefore, targeting tau protein has the potential to provide new treatments for these disorders.

TTBK2: A Key Component of Microtubules

Microtubules are composed of several protein building blocks that are organized in a specific sequence to form a highly organized structure. The most well-known protein component of microtubules is the tau protein, which is a key regulator of microtubule dynamics and stability. Tau protein is composed of several domains, including an N-terminus, a T-terminus, a middle body, and a C-terminus. The tau protein plays a critical role in the regulation of microtubule stability and dynamics by interacting with several other proteins, including microtubule -associated protein 1 (MAP1), microtubule-associated protein 2 (MAP2), and p16.

TTBK2: A Putative Drug Target

The tau protein has been implicated in the development and progression of numerous neurological disorders, including Alzheimer's disease, Parkinson's disease, and Huntington's disease. The dysfunction of microtubules has been implicated in the pathophysiology of these disorders, and targeting tau protein has the potential to provide new treatments for these disorders. Therefore, TTBK2, a protein that is known to interact with tau protein, has the potential to be a drug target for the treatment of neurological disorders.

TTBK2: A Potential Biomarker

TTBK2 has also been identified as a potential biomarker for the diagnosis and prognosis of neurological disorders. The dysfunction of microtubules has been implicated in the development and progression of numerous neurological disorders, including Alzheimer's disease, Parkinson's disease, and Huntington's disease. Therefore, measuring the levels of TTBK2 may provide a diagnostic or prognostic indicator for these disorders. Additionally, the inhibition of TTBK2 has been shown to protect against the neurotoxicity of several neurotoxins, including 6-OHDA, which is known to cause neurodegeneration in animal models of Parkinson's disease. Therefore, TTBK2 may also be a potential biomarker for the diagnosis and treatment of Parkinson's disease.

TTBK2: A Potential Therapeutic Approach

TTBK2 has been shown to interact with several other proteins, including microtubule-associated protein 1 (MAP1), microtubule-associated protein 2 (MAP2), and p16. Therefore, targeting TTBK2 may be a novel therapeutic approach for the treatment of neurological disorders. Several studies have shown that inhibiting the activity of TTBK2 has the potential to reverse the neurotoxicity of several neurotoxins, including 6-OHDA, and protect against the development of neurodegeneration in animal models of Parkinson's disease.

Conclusion

In conclusion, TTBK2 is a protein that has been implicated in the development and progression of numerous neurological disorders. The dysfunction of microtubules has been implicated in the pathophysiology of these disorders, and targeting tau protein, as seen in TTBK2, has the potential to provide new treatments for these disorders. Additionally, TTBK2 has also been identified as a potential biomarker for the diagnosis and treatment of these disorders. Therefore, TTBK2 may be a promising target for the development of new therapeutic approaches for the treatment of neurological disorders.

Protein Name: Tau Tubulin Kinase 2

Functions: Serine/threonine kinase that acts as a key regulator of ciliogenesis: controls the initiation of ciliogenesis by binding to the distal end of the basal body and promoting the removal of CCP110, which caps the mother centriole, leading to the recruitment of IFT proteins, which build the ciliary axoneme. Has some substrate preference for proteins that are already phosphorylated on a Tyr residue at the +2 position relative to the phosphorylation site. Able to phosphorylate tau on serines in vitro (PubMed:23141541). Phosphorylates MPHOSPH9 which promotes its ubiquitination and proteasomal degradation, loss of MPHOSPH9 facilitates the removal of the CP110-CEP97 complex (a negative regulator of ciliogenesis) from the mother centrioles, promoting the initiation of ciliogenesis (PubMed:30375385)
