TBK1 (TANK-Binding Kinase 1) is a serine/threonine protein kinase located on chromosome 12q14.1, encoding a 729-amino acid protein essential for innate immune signaling and autophagy regulation. Mutations in TBK1 are associated with amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and herpes simplex encephalitis, making it a critical gene in neurodegenerative disease research. TBK1 phosphorylates and activates key autophagy receptors including optineurin and p62/SQSTM1 to promote clearance of damaged mitochondria and protein aggregates.
TBK1 encodes TANK-binding kinase 1, a serine/threonine protein kinase essential for innate immune signaling and autophagy regulation. In the nervous system, TBK1 phosphorylates and activates key autophagy receptors including optineurin and p62/SQSTM1 to promote clearance of damaged mitochondria and protein aggregates. TBK1 is also critical for type I interferon production and inflammatory responses.
Expressed in neurons, microglia, astrocytes, and oligodendrocytes. Highest expression in motor cortex, hippocampus, and spinal cord. Expression is induced by inflammatory stimuli and cellular stress.
| Disease | Variants | Inheritance | Mechanism |
|---|---|---|---|
| Amyotrophic Lateral Sclerosis | E696X, R444X, 1901_1903del, R47H, R135H | Autosomal dominant | Haploinsufficiency, impaired mitophagy, dysregulated inflammation |
| Frontotemporal Dementia | L159P, R359X, 1901_1903del | Autosomal dominant | Similar to ALS mechanism |
| Hereditary Herpes Simplex Encephalitis | I252T | Autosomal recessive | Impaired innate immune response |
