TBK1
protein-codingTANK binding kinase 1, the group of I kappa B kinases
Gene summary
The NF-kappa-B (NFKB) complex of proteins is inhibited by I-kappa-B (IKB) proteins, which inactivate NFKB by trapping it in the cytoplasm. Phosphorylation of serine residues on the IKB proteins by IKB kinases marks them for destruction via the ubiquitination pathway, thereby allowing activation and nuclear translocation of the NFKB complex. The protein encoded by this gene is similar to IKB kinases and can mediate NFKB activation in response to certain growth factors. The protein is also an important kinase for antiviral innate immunity response. [provided by RefSeq, Sep 2021]

*TBK1* was first reported in relation to autosomal dominant amyotrophic lateral sclerosis in 2015 (Cirulli et al. Science (2015); PMID: 25700176 and Freischmidt et al. Nat Neurosci (2015); PMID: 25803835). Per criteria outlined by the ClinGen Lumping and Splitting Working Group, we found difference in molecular mechanism(s) and phenotypic variability. Therefore, the following disease entities have been split into multiple disease entities, amyotrophic lateral sclerosis (OMIM:616439) and herpes simplex virus encephalitis (OMIM:617900). A case-control genome-wide gene burden analysis of whole-exome sequencing data from 4,187 cases and 8,776 controls identified a burden of "dominant not benign" variants in *TBK1* among ALS cases compared to controls (PMID: 25700176). A further seven loss of function variants that have been reported in seven probands in two publications (PMIDs: 25803835, 30033073) are also included in this curation, as well as two splicing and nine missense variants publications (PMIDs: 25803835, 30033073). More evidence is available in the literature, but the maximum score for genetic evidence (12 pts.) has been reached. The mechanism of pathogenicity is reported to be loss of function. This gene-disease association is also supported by experimental evidence including protein interactions, expression studies, in vitro functional assays, cell models and an animal models (PMIDs: 25803835, 32413959, 30033073, 30939964, 33312375, 22921120, 25613900, 36201573). In summary, *TBK1* is definitively associated with autosomal dominant amyotrophic lateral sclerosis. This has been repeatedly demonstrated in both the research and clinical diagnostic settings, and has been upheld over time. This classification was approved by the ClinGen ALS GCEP on the meeting date June 23, 2022 (SOP Version 9).

- Function
- FUNCTION: Serine/threonine kinase that plays an essential role in regulating inflammatory responses to foreign agents. Following activation of toll-like receptors by viral or bacterial components, associates with TRAF3 and TANK and phosphorylates interferon regulatory factors (IRFs) IRF3 and IRF7 as well as DDX3X. This activity allows subsequent homodimerization and nuclear translocation of the IRFs leading to transcriptional activation of pro-inflammatory and antiviral genes including IFNA and IFNB. In order to establish such an antiviral state, TBK1 form several different complexes whose composition depends on the type of cell and cellular stimuli. Thus, several scaffolding molecules including FADD, TRADD, MAVS, AZI2, TANK or TBKBP1/SINTBAD can be recruited to the TBK1-containing-complexes. Under particular conditions, functions as a NF-kappa-B effector by phosphorylating NF-kappa-B inhibitor alpha/NFKBIA, IKBKB or RELA to translocate NF-Kappa-B to the nucleus. Restricts bacterial proliferation by phosphorylating the autophagy receptor OPTN/Optineurin on 'Ser- 177', thus enhancing LC3 binding affinity and antibacterial autophagy (PubMed:21617041). Phosphorylates SMCR8 component of the C9orf72-SMCR8 complex, promoting autophagosome maturation (PubMed:27103069). Phosphorylates and activates AKT1 (PubMed:21464307). Seems to play a role in energy balance regulation by sustaining a state of chronic, low-grade inflammation in obesity, wich leads to a negative impact on insulin sensitivity. Attenuates retroviral budding by phosphorylating the endosomal sorting complex required for transport-I (ESCRT-I) subunit VPS37C (PubMed:21270402). Phosphorylates Borna disease virus (BDV) P protein (PubMed:16155125). Plays an essential role in the TLR3- and IFN- dependent control of herpes virus HSV-1 and HSV-2 infections in the central nervous system (PubMed:22851595). {ECO:0000269|PubMed:10581243, ECO:0000269|PubMed:10783893, ECO:0000269|PubMed:11839743, ECO:0000269|PubMed:12692549, ECO:0000269|PubMed:12702806, ECO:0000269|PubMed:14703513, ECO:0000269|PubMed:15367631, ECO:0000269|PubMed:15485837, ECO:0000269|PubMed:15489227, ECO:0000269|PubMed:16155125, ECO:0000269|PubMed:18583960, ECO:0000269|PubMed:21138416, ECO:0000269|PubMed:21270402, ECO:0000269|PubMed:21464307, ECO:0000269|PubMed:21617041, ECO:0000269|PubMed:21931631, ECO:0000269|PubMed:22851595, ECO:0000269|PubMed:23453971, ECO:0000269|PubMed:23453972, ECO:0000269|PubMed:23746807, ECO:0000269|PubMed:26611359, ECO:0000269|PubMed:27103069}.;
- Disease
- DISEASE: Glaucoma 1, open angle, P (GLC1P) [MIM:177700]: A form of primary open angle glaucoma (POAG). POAG is characterized by a specific pattern of optic nerve and visual field defects. The angle of the anterior chamber of the eye is open, and usually the intraocular pressure is increased. However, glaucoma can occur at any intraocular pressure. The disease is generally asymptomatic until the late stages, by which time significant and irreversible optic nerve damage has already taken place. GLC1P is characterized by early onset, thin central corneas and low intraocular pressure. {ECO:0000269|PubMed:21447600, ECO:0000269|PubMed:22306015}. Note=The disease may be caused by mutations affecting the gene represented in this entry. A copy number variation on chromosome 12q14 consisting of a 300 kb duplication that includes TBK1, XPOT, RASSF3 and GNS has been found in individuals affected by glaucoma. TBK1 is the most likely candidate for the disorder (PubMed:21447600). {ECO:0000269|PubMed:21447600}.; DISEASE: Frontotemporal dementia and/or amyotrophic lateral sclerosis 4 (FTDALS4) [MIM:616439]: A neurodegenerative disorder characterized by frontotemporal dementia and/or amyotrophic lateral sclerosis in affected individuals. There is high intrafamilial variation. Frontotemporal dementia is characterized by frontal and temporal lobe atrophy associated with neuronal loss, gliosis, and dementia. Patients exhibit progressive changes in social, behavioral, and/or language function. Amyotrophic lateral sclerosis is characterized by the death of motor neurons in the brain, brainstem, and spinal cord, resulting in fatal paralysis. {ECO:0000269|PubMed:25803835, ECO:0000269|PubMed:25943890}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Encephalopathy, acute, infection-induced, herpes- specific, 8 (IIAE8) [MIM:617900]: A rare, often fatal complication of herpes simplex infection, caused by virus spreading in the central nervous system. Disease manifestations include low-grade fever, severe headache, nausea, vomiting, and lethargy. Neurological features include confusion, acute memory disturbances, disorientation, behavioral changes, hemiparesis and seizures. {ECO:0000269|PubMed:22851595, ECO:0000269|PubMed:26513235}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.;
