[[http://www.uniprot.org/uniprot/TBK1_HUMAN TBK1_HUMAN]] 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 IFN-alpha and IFN-beta. 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 or 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. Attenuates retroviral budding by phosphorylating the endosomal sorting complex required for transport-I (ESCRT-I) subunit VPS37C. Phosphorylates and activates AKT1. Phosphorylates Borna disease virus (BDV) P protein.<ref>PMID:10581243</ref> <ref>PMID:10783893</ref> <ref>PMID:11839743</ref> <ref>PMID:12692549</ref> <ref>PMID:12702806</ref> <ref>PMID:14703513</ref> <ref>PMID:15485837</ref> <ref>PMID:15489227</ref> <ref>PMID:15367631</ref> <ref>PMID:18583960</ref> <ref>PMID:21270402</ref> <ref>PMID:21464307</ref> <ref>PMID:21617041</ref> <ref>PMID:21138416</ref>

== Publication Abstract from PubMed ==
Upon stimulation by pathogen-associated inflammatory signals, TANK-binding kinase 1 (TBK1) induces type I interferon expression and modulates nuclear factor kappaB (NF-kappaB) signaling. Here, we describe the 2.4 A-resolution crystal structure of nearly full-length TBK1 in complex with specific inhibitors. The structure reveals a dimeric assembly created by an extensive network of interactions among the kinase, ubiquitin-like, and scaffold/dimerization domains. An intact TBK1 dimer undergoes K63-linked polyubiquitination on lysines 30 and 401, and these modifications are required for TBK1 activity. The ubiquitination sites and dimer contacts are conserved in the close homolog inhibitor of kappaB kinase epsilon (IKKepsilon) but not in IKKbeta, a canonical IKK that assembles in an unrelated manner. The multidomain architecture of TBK1 provides a structural platform for integrating ubiquitination with kinase activation and IRF3 phosphorylation. The structure of TBK1 will facilitate studies of the atypical IKKs in normal and disease physiology and further the development of more specific inhibitors that may be useful as anticancer or anti-inflammatory agents.
