Function

Serine/threonine kinase that plays an essential role in regulating inflammatory responses to foreign agents (PubMed:12692549, PubMed:14703513, PubMed:18583960, PubMed:12702806, PubMed:15367631, PubMed:10581243, PubMed:11839743, PubMed:15485837, PubMed:21138416, PubMed:25636800, PubMed:23453971, PubMed:23453972, PubMed:23746807, PubMed:26611359, PubMed:32404352). 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 (PubMed:12692549, PubMed:14703513, PubMed:18583960, PubMed:12702806, PubMed:15367631, PubMed:25636800). 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 (PubMed:12702806, PubMed:15367631, PubMed:25636800, PubMed:32972995). In order to establish such an antiviral state, TBK1 form several different complexes whose composition depends on the type of cell and cellular stimuli (PubMed:23453971, PubMed:23453972, PubMed:23746807). Plays a key role in IRF3 activation: acts by first phosphorylating innate adapter proteins MAVS, STING1 and TICAM1 on their pLxIS motif, leading to recruitment of IRF3, thereby licensing IRF3 for phosphorylation by TBK1 (PubMed:25636800, PubMed:30842653). Phosphorylated IRF3 dissociates from the adapter proteins, dimerizes, and then enters the nucleus to induce expression of interferons (PubMed:25636800). Thus, several scaffolding molecules including FADD, TRADD, MAVS, AZI2, TANK or TBKBP1/SINTBAD can be recruited to the TBK1-containing-complexes (PubMed:21931631). 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 (PubMed:10783893, PubMed:15489227). 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 (By similarity). 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).

Activity summary

The NAK/TBK1 also known as TANK-binding kinase 1 is a fundamental protein kinase in various cellular processes. It weighs approximately 84 kDa and is expressed in many tissues including lymphoid organs and the brain. NAK acts as a serine/threonine-protein kinase which transfers a phosphate group to specific substrates modulating their function and activity. Phosphorylation by TBK1 initiates several signaling events making it an important regulator in immune responses and inflammatory signaling pathways.

Biological function summary

This kinase plays a significant role in antiviral defense and autophagy. NAK/TBK1 is also involved in innate immune signaling and cell survival. TBK1 forms part of a larger signaling complex interacting with adaptors like TRAF3 and TANK which are important for its proper localization and function. Phospho-NAK its phosphorylated form can activate other molecules driving various downstream immune and stress responses.

Pathways

The protein is integral to the type I interferon signaling pathway and NF-kB pathway. NAK/TBK1 interacts closely with IRF3 a transcription factor important for antiviral activity and plays a role alongside other proteins like IKKε. These interactions permit activation of genes necessary for defense mechanisms against viral pathogens and control of inflammation. In the NF-kB pathway TBK1 helps regulate cellular responses to stress and inflammatory signals.

Associated diseases and disorders

NAK/TBK1 has associations with amyotrophic lateral sclerosis (ALS) and various cancers. Research shows connections between TBK1 mutations and ALS indicating its importance in neuronal function and health. Additionally aberrations in TBK1 activity contribute to oncogenesis as it can affect cell proliferation and survival. The protein's relation with signaling proteins such as p62/SQSTM1 highlights its diverse role in disease mechanisms making it a potential therapeutic target.
