Ttbk2 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Overview
TTBK2 encodes [Tau](/proteins/tau) tubulin kinase 2, a serine/threonine kinase highly expressed in cerebellar Purkinje cells and involved in neuronal development, ciliary function, and tau phosphorylation. Mutations in TTBK2 cause Spinocerebellar Ataxia type 11 (SCA11), characterized by progressive cerebellar degeneration. TTBK2 is also implicated in Alzheimer's disease through tau phosphorylation pathways. [@boutte2020]

Gene Information
Function
TTBK2 is a neuronal kinase with multiple functions:
Tau phosphorylation: Phosphorylates tau at multiple AD-related sites
Ciliary function: Essential for ciliogenesis and hedgehog signaling
Neuronal development: Regulates Purkinje cell development and dendrite morphology
The study of Ttbk2 Gene has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
