Gene Description

TANK (TRAF family member-associated NF-kappa-B activator; also known as I-TRAF) is a cytoplasmic adaptor/scaffold protein, lacking any catalytic activity, that organizes signaling complexes in the innate immune and NF-kappaB pathways. It was first identified as a TRAF-interacting protein that binds the TRAF-C domains of TRAF1, TRAF2 and TRAF3 and modulates TRAF-mediated signaling. Its best-established role is as one of three mutually exclusive adaptors (alongside SINTBAD/TBKBP1 and NAP1/AZI2) that constitutively bind the IKK-related kinases TBK1 and IKBKE (IKKepsilon) via a central TBK1-binding domain and bridge them into complexes that phosphorylate IRF3/IRF7, driving type I interferon production during antiviral innate immunity; TBK1 activation in response to virus or poly(I:C) depends on the TANK-TBK1 interaction. TANK is the non-catalytic subunit of the TBK1-IKKepsilon-TANK kinase complex. TANK also has a separable negative-regulatory function: in response to genotoxic stress or interleukin-1/LPS it scaffolds a deubiquitination complex containing ZC3H12A (MCPIP1) and the deubiquitinase USP10, promoting USP10-dependent deubiquitination of TRAF6 (and NEMO/IKBKG) and thereby restraining canonical NF-kappaB activation. TANK itself contains no deubiquitinase domain, so its activity in this complex is purely as an assembly scaffold. Phosphorylation of TANK by IKBKE disrupts its binding to TRAF2, providing a phospho-switch on its adaptor function. Structurally TANK contains an N-terminal coiled-coil, a TBK1/IKBKE-binding region, a TRAF-interaction motif (which engages the CD40-recognition site of TRAF3), and a C-terminal UBZ1-type zinc finger. TANK is targeted by viral proteases (encephalomyocarditis virus and Seneca Valley virus 3C proteases cleave it; vaccinia C6 binds it) as an immune-evasion strategy, underscoring its role in the antiviral interferon response.

Summary: ComplexPortal author-statement assignment of type I interferon-mediated signaling for the TBK1-IKKepsilon-TANK complex. Note this term denotes the response to interferon; TANK's documented role is in interferon induction/production rather than IFN-receptor signaling.
Reason: Process is closely related to TANK's antiviral IFN role; however GO:0060337 (the response to type I IFN) is less precise for TANK than GO:0032481 (positive regulation of type I interferon production), which is the experimentally supported core BP.

Summary: TANK lacks a deubiquitinase domain; the contributes_to qualifier reflects that TANK scaffolds the USP10-dependent deubiquitination of TRAF6, not that TANK itself has DUB activity. The catalytic DUB is USP10.
Reason: The contributes_to qualifier is acceptable for a non-catalytic scaffold that enables a complex DUB activity, but the activity resides in USP10; TANK's actual function here is better captured by molecular adaptor activity (GO:0060090) and deubiquitinase activator activity (GO:0035800).

Core Functions

Functions as a non-catalytic molecular adaptor/scaffold that constitutively binds the IKK-related kinases TBK1 and IKBKE (IKKepsilon) and bridges them into cytoplasmic signaling complexes that phosphorylate IRF3/IRF7, driving type I interferon production during antiviral innate immunity.

Molecular Function:
molecular adaptor activity
Directly Involved In:
positive regulation of type I interferon production
Cellular Locations:
cytoplasm
Supporting Evidence:
  • PMID:21931631
    TBK1 activation was strictly dependent on the integrity of the TBK1/TANK interaction

Acts as a scaffold that assembles a deubiquitination complex with ZC3H12A/MCPIP1 and the deubiquitinase USP10, promoting USP10-dependent deubiquitination of TRAF6 (and NEMO/IKBKG) to restrain genotoxic- and IL-1/LPS-induced canonical NF-kappaB activation. TANK itself has no deubiquitinase activity.

Molecular Function:

Directly Involved In:
negative regulation of canonical NF-kappaB signal transduction
Cellular Locations:

Suggested Questions for Experts

Q: How is TANK's dual behaviour - positive regulation of TBK1/IKKepsilon-driven type I interferon induction versus negative regulation of canonical NF-kappaB via the USP10/ZC3H12A deubiquitination complex - partitioned between stimuli, subcellular pools, and post-translational states (phosphorylation by IKBKE, SUMOylation)?

Q: Given that TANK, SINTBAD and NAP1 compete for the same site on TBK1 and occupy distinct subcellular locations, what determines which adaptor is used for a given TBK1-dependent output (antiviral IFN versus autophagy/selective autophagy)?

Suggested Experiments

Experiment: Stimulus-resolved interactome (AP-MS/proximity labeling) of endogenous TANK under viral/poly(I:C) stimulation versus genotoxic stress and IL-1 to map the switch between the TBK1-IKKepsilon kinase complex and the USP10-ZC3H12A deubiquitination complex.

Experiment: Separation-of-function mutants (TBK1-binding-deficient versus TRAF6/ZC3H12A-binding-deficient TANK) reconstituted into TANK-knockout cells to independently test the contribution of each scaffold function to type I IFN induction and NF-kappaB resolution.

Summary of function

TANK is a cytoplasmic adaptor/scaffold protein with no catalytic activity. It was
originally cloned as a TRAF-interacting protein ("I-TRAF") that binds the TRAF-C
domains of TRAF1, TRAF2 and TRAF3 and was proposed to keep TRAFs in a latent state
PMID:8710854.
Its best-established role is as one of three mutually exclusive adaptors (with SINTBAD/TBKBP1
and NAP1/AZI2) that bridge the IKK-related kinases TBK1 and IKBKE (IKKε) into signaling
complexes that drive IRF3/IRF7 phosphorylation and type I interferon induction during
antiviral innate immunity PMID:21931631.

The adaptors bind the same C-terminal coiled-coil 2 of TBK1 and compete for it; TANK
resides in a distinct subcellular pool from SINTBAD/NAP1 PMID:21931631.

TANK also has a separable negative-regulatory function. In response to genotoxic stress
(DNA damage) or IL-1β/LPS, TANK acts as a scaffold assembling a deubiquitination complex
with ZC3H12A (MCPIP1) and the deubiquitinase USP10, facilitating USP10-dependent
deubiquitination of TRAF6 (and IKBKG/NEMO), thereby restraining NF-kB activation
PMID:25861989.
TANK itself lacks a DUB domain — its GO annotations to "cysteine-type deubiquitinase
activity" (contributes_to) and "deubiquitinase activator activity" reflect this scaffolding
role, not intrinsic enzymatic activity.

Phosphorylation by IKBKE disrupts the TANK–TRAF2 interaction [UniProt SUBUNIT; PMID:10759890],
giving a phospho-switch on its TRAF-binding adaptor function.

Domains / structure

  • N-terminal coiled-coil (aa 22–62); region 1–31 needed for ZC3H12A interaction.
  • TBD (TBK1-binding domain) region ~133–172 binds TBK1 and IKBKE.
  • TRAF family interaction region ~172–191 (crystal structure 1L0A/1KZZ of TANK 174–194
    bound to TRAF3; binds the CD40 recognition site on TRAF3) PMID:12005438.
  • C-terminal UBZ1-type zinc finger (aa 393–420) — basis of the IEA "zinc ion binding"
    keyword annotation.

Localization

  • UniProt: Cytoplasm. Experimental IDA "is_active_in cytoplasm" PMID:21931631.
  • HPA IDA: cytosol (GO:0005829) and nucleolus (GO:0005730). The nucleolus annotation
    is from a single high-throughput immunofluorescence dataset (GO_REF:0000052); there is
    no functional literature placing TANK function in the nucleolus, so it is non-core.

Host–virus interactions (context, not core GO BP for the gene's normal function)

  • Vaccinia C6 binds TANK and other TBK1 adaptors to inhibit IRF3/IRF7 PMID:21931555.
  • EMCV 3C and Seneca Valley virus 3C proteases cleave TANK to disrupt the
    TANK-TBK1-IKKε-IRF3 complex and suppress type I IFN [UniProt PTM; PMID:26363073, PMID:28566380].
    These confirm TANK's role in the antiviral IFN axis.

Annotation assessment highlights

  • Core MF: molecular adaptor activity (GO:0060090, IDA, PMID:21931631) — ACCEPT as core.
  • Core BP: positive regulation of type I interferon production (GO:0032481, IDA) — ACCEPT as core.
  • ubiquitin protein ligase binding (GO:0031625, IPI, PMID:11279055) — real TRAF-binding,
    informative MF; KEEP_AS_NON_CORE (more specific than bare protein binding but secondary).
  • The deubiquitination-complex BP/MF terms (GO:0035800, GO:0004843 contributes_to,
    GO:1903003, GO:2000158, GO:0043124, GO:0006974, GO:0071347, GO:0071356, GO:0071479)
    are all from the single IMP study PMID:25861989 and describe the genotoxic
    NF-kB-restraining scaffold role — accept as a real but secondary (non-core) function set.
  • The ~30 bare "protein binding" (GO:0005515) IPI entries are individually uninformative
    per curation guidelines (KEEP_AS_NON_CORE); the functionally meaningful partners
    (TBK1, IKBKE, TRAF1/2/3, IKBKG/NEMO, USP10, ZC3H12A) are captured by the adaptor/IFN core.
  • ~30 Reactome TAS "cytosol" (GO:0005829) entries are pathway-step localizations; correct
    compartment but redundant — KEEP_AS_NON_CORE.
  • GO:1902554 serine/threonine protein kinase complex (NAS, ComplexPortal, the
    TBK1-IKKε-TANK complex CPX-6089) — ACCEPT/KEEP_AS_NON_CORE as a real complex membership
    (TANK is the non-catalytic adaptor subunit of the kinase complex).
  • IEA GO:0043124 (neg reg canonical NF-kB) from InterPro is corroborated by the experimental
    IMP of the same term — KEEP_AS_NON_CORE.
  • GO:0051607 (defense response to virus) and GO:0060337 (type I interferon-mediated
    signaling pathway), both NAS ComplexPortal from PMID:21931631 — consistent with the
    antiviral IFN role; KEEP_AS_NON_CORE (process-level).

AIGR Review Snapshot

  • Description: TANK (TRAF family member-associated NF-kappa-B activator; also known as I-TRAF) is a cytoplasmic adaptor/scaffold protein, lacking any catalytic activity, that organizes signaling complexes in the innate immune and NF-kappaB pathways. It was first identified as a TRAF-interacting protein that binds the TRAF-C domains of TRAF1, TRAF2 and TRAF3 and modulates TRAF-mediated signaling. Its best-established role is as one of three mutually exclusive adaptors (alongside SINTBAD/TBKBP1 and NAP1/AZI2) that constitutively bind the IKK-related kinases TBK1 and IKBKE (IKKepsilon) via a central TBK1-binding domain and bridge them into complexes that phosphorylate IRF3/IRF7, driving type I interferon production during antiviral innate immunity; TBK1 activation in response to virus or poly(I:C) depends on the TANK-TBK1 interaction. TANK is the non-catalytic subunit of the TBK1-IKKepsilon-TANK kinase complex. TANK also has a separable negative-regulatory function: in response to genotoxic stress or interleukin-1/LPS it scaffolds a deubiquitination complex containing ZC3H12A (MCPIP1) and the deubiquitinase USP10, promoting USP10-dependent deubiquitination of TRAF6 (and NEMO/IKBKG) and thereby restraining canonical NF-kappaB activation. TANK itself contains no deubiquitinase domain, so its activity in this complex is purely as an assembly scaffold. Phosphorylation of TANK by IKBKE disrupts its binding to TRAF2, providing a phospho-switch on its adaptor function. Structurally TANK contains an N-terminal coiled-coil, a TBK1/IKBKE-binding region, a TRAF-interaction motif (which engages the CD40-recognition site of TRAF3), and a C-terminal UBZ1-type zinc finger. TANK is targeted by viral proteases (encephalomyocarditis virus and Seneca Valley virus 3C proteases cleave it; vaccinia C6 binds it) as an immune-evasion strategy, underscoring its role in the antiviral interferon response.

PN Consistency Summary

  • Consistency: Major divergence. The review and TANK-notes contain NO autophagy/mitophagy content at all — TANK is treated purely as (1) the non-catalytic adaptor/scaffold of the TBK1-IKKepsilon-TANK complex driving type I IFN (GO:0060090 molecular adaptor, ACCEPT; GO:0032481 positive regulation of type I IFN production), (2) a scaffold that activates USP10-dependent deubiquitination of TRAF6/NEMO to restrain NF-kB (GO:0035800 deubiquitinase activator activity), and (3) a TRAF1/2/3 binder. The PN's mitophagy story ("TANK-TBK1 complex phosphorylates OPTN in mitophagy") rests on a single PNAS paper (Richter/Heo 2016) and is absent from the review.
  • PN story / NEW pressure: PN asserts a role (GO:0000423 mitophagy, new_to_goa) NOT in GOA and NOT in the review. This is an over-reach. TANK is the regulatory/scaffold subunit that bridges TBK1 — it does not itself perform mitophagy. The connection is indirect (TANK→TBK1→OPTN-P→mitophagy). At most this warrants a regulation term, and even that is thin: the PNAS paper foregrounds TBK1/OPTN, with TANK as part of the kinase complex. Bare GO:0000423 mitophagy involved_in is not defensible for TANK on current evidence; treat as candidate/context, not ADD.
  • Evidence alignment: No overlap on the autophagy axis — PN's sole mitophagy ref (Richter/Heo PNAS) is not in the TANK review (the review's TBK1 interactions are IFN/NF-kB-context IPIs). The shared PNAS paper IS used in OPTN and TBK1 reviews, not TANK.
  • Verdict: OVER-REACH — PN projects GO:0000423 mitophagy (new_to_goa) onto TANK with no support in review/notes; TANK is an indirect regulatory scaffold of TBK1. Recommended edits: [MAP] drop/demote TANK's "Autophagy receptor regulation|Mitophagy"→GO:0000423 projection (indirect, single-paper, regulatory-subunit role) — at most a regulation-of-mitophagy context, not a direct mitophagy annotation; do not add to the review without TANK-specific evidence.

  • Consistency: Major divergence. The review and TANK-notes contain NO autophagy/mitophagy content at all — TANK is treated purely as (1) the non-catalytic adaptor/scaffold of the TBK1-IKKepsilon-TANK complex driving type I IFN (GO:0060090 molecular adaptor, ACCEPT; GO:0032481 positive regulation of type I IFN production), (2) a scaffold that activates USP10-dependent deubiquitination of TRAF6/NEMO to restrain NF-kB (GO:0035800 deubiquitinase activator activity), and (3) a TRAF1/2/3 binder. The PN's mitophagy story ("TANK-TBK1 complex phosphorylates OPTN in mitophagy") rests on a single PNAS paper (Richter/Heo 2016) and is absent from the review.
  • PN story / NEW pressure: PN asserts a role (GO:0000423 mitophagy, new_to_goa) NOT in GOA and NOT in the review. This is an over-reach.

Bare GO:0000423 mitophagy involved_in is not defensible for TANK on current evidence; treat as candidate/context, not ADD.
  • Mapping strategy: This gene does NOT justify the node's mitophagy mapping for TANK. The PN node "Autophagy receptor regulation" projecting bare GO:0000423 (a process, not a regulation term) is the same scope drift seen for TBK1, but weaker here because TANK is one step further removed (regulatory adaptor of the kinase). KEY PATTERN: TANK is the regulatory adaptor (per the brief), not a receptor — cargo-adaptor MF does not apply; its MF is GO:0060090 molecular adaptor (already core).
  • Evidence alignment: No overlap on the autophagy axis — PN's sole mitophagy ref (Richter/Heo PNAS) is not in the TANK review (the review's TBK1 interactions are IFN/NF-kB-context IPIs). The shared PNAS paper IS used in OPTN and TBK1 reviews, not TANK.
  • Verdict: OVER-REACH — PN projects GO:0000423 mitophagy (new_to_goa) onto TANK with no support in review/notes; TANK is an indirect regulatory scaffold of TBK1.

  • UniProt: Q92844
  • In branches: ALP, UPS
  • Notes: TANK-TBK1 complex phosphorylates OPTN in mitophagy.

      status=mapped scope=ok_for_propagation_to_go GO=[GO:0000423 mitophagy]
      rationale: The PN receptor-regulation type for mitophagy captures factors that tune receptor activity within the mitophagy pathway. This supports propagation to mitophagy while preserving that the source is a regulatory sub-role.
    • [group] Autophagy-Lysosome Pathway|Autophagy substrate selection|Autophagy receptor regulation
      status=no_mapping scope= GO=[]
      rationale: Reviewed as a broad PN taxonomy container. The descendants mix components, regulators, context labels, and mechanistic leaves, so propagation should come only from narrower curated nodes.
    • [class] Autophagy-Lysosome Pathway|Autophagy substrate selection
      status=no_mapping scope= GO=[]
      rationale: Reviewed as a broad substrate-selection container. GO has useful targets for specific receptor, cargo-adaptor, and selective-autophagy leaves, but this class mixes marking, recognition, receptor regulation, and unknown roles and should not propagate as one term.
    • [branch] Autophagy-Lysosome Pathway
      status=no_mapping scope= GO=[]
      rationale: Reviewed as the top-level PN branch. It is a project taxonomy umbrella rather than a direct GO assertion; all propagation must come from manually curated child nodes.

      rationale: Reviewed manually as a UPS source node. No single GO term is appropriate for direct propagation from this PN label without narrower context or gene-level evidence.
    • [type] Ubiquitin Proteasome System|Ubiquitin and UBL binding|DUB cofactor|USP10
      status=no_mapping scope= GO=[]
      rationale: Reviewed as a UPS taxonomy container. Its descendants mix catalytic roles, complex membership, binding domains, regulators, adaptors, and substrate-context labels, so a single propagating GO assertion would overstate the shared biology.
    • [group] Ubiquitin Proteasome System|Ubiquitin and UBL binding|DUB cofactor
      status=no_mapping scope= GO=[]
      rationale: Reviewed as a cofactor, possible adaptor, or related-family bucket. The label is useful in PN but does not establish a safe direct GO propagation.

      status=context_only scope=too_broad_to_propagate GO=[GO:0140036 ubiquitin-modified protein reader activity]
      rationale: This class records ubiquitin/UBL-reader context, but the subtree mixes ubiquitin, SUMO, UBL-domain, domain-architecture, catalytic, signaling, trafficking, and nucleic-acid process buckets. It is useful context, not a safe direct propagation.
    • [branch] Ubiquitin Proteasome System

  TANK (TRAF family member-associated NF-kappa-B activator; also known as I-TRAF)
  is a cytoplasmic adaptor/scaffold protein, lacking any catalytic activity, that
  organizes signaling complexes in the innate immune and NF-kappaB pathways. It was
  first identified as a TRAF-interacting protein that binds the TRAF-C domains of
  TRAF1, TRAF2 and TRAF3 and modulates TRAF-mediated signaling. Its best-established
  role is as one of three mutually exclusive adaptors (alongside SINTBAD/TBKBP1 and
  NAP1/AZI2) that constitutively bind the IKK-related kinases TBK1 and IKBKE (IKKepsilon)
  via a central TBK1-binding domain and bridge them into complexes that phosphorylate
  IRF3/IRF7, driving type I interferon production during antiviral innate immunity;
  TBK1 activation in response to virus or poly(I:C) depends on the TANK-TBK1 interaction.
  TANK is the non-catalytic subunit of the TBK1-IKKepsilon-TANK kinase complex.
  TANK also has a separable negative-regulatory function: in response to genotoxic
  stress or interleukin-1/LPS it scaffolds a deubiquitination complex containing
  ZC3H12A (MCPIP1) and the deubiquitinase USP10, promoting USP10-dependent
  deubiquitination of TRAF6 (and NEMO/IKBKG) and thereby restraining canonical
  NF-kappaB activation. TANK itself contains no deubiquitinase domain, so its activity
  in this complex is purely as an assembly scaffold. Phosphorylation of TANK by IKBKE
  disrupts its binding to TRAF2, providing a phospho-switch on its adaptor function.
  Structurally TANK contains an N-terminal coiled-coil, a TBK1/IKBKE-binding region,
  a TRAF-interaction motif (which engages the CD40-recognition site of TRAF3), and a
  C-terminal UBZ1-type zinc finger. TANK is targeted by viral proteases (encephalomyocarditis
  virus and Seneca Valley virus 3C proteases cleave it; vaccinia C6 binds it) as an
  immune-evasion strategy, underscoring its role in the antiviral interferon response.

  findings:
  - statement: TANK scaffolds a complex with ZC3H12A/MCPIP1 and the deubiquitinase USP10 that mediates USP10-dependent deubiquitination of TRAF6, restraining genotoxic- and IL-1/LPS-induced canonical NF-kappaB activation. CRISPR deletion of TANK enhances NF-kappaB activation, cell survival and cytokine production after genotoxic stress. TANK has no DUB domain of its own.

core_functions:
- description: Functions as a non-catalytic molecular adaptor/scaffold that constitutively
    binds the IKK-related kinases TBK1 and IKBKE (IKKepsilon) and bridges them into
    cytoplasmic signaling complexes that phosphorylate IRF3/IRF7, driving type I interferon
    production during antiviral innate immunity.

- description: Acts as a scaffold that assembles a deubiquitination complex with ZC3H12A/MCPIP1
    and the deubiquitinase USP10, promoting USP10-dependent deubiquitination of TRAF6
    (and NEMO/IKBKG) to restrain genotoxic- and IL-1/LPS-induced canonical NF-kappaB
    activation. TANK itself has no deubiquitinase activity.

- description: Binds the TRAF-C domains of TRAF1/2/3 (originally identified as the TRAF-interacting
    protein I-TRAF) and is the non-catalytic subunit of the TBK1-IKKepsilon-TANK serine/threonine
    kinase complex; phosphorylation by IKBKE disrupts TANK-TRAF2 binding, providing
    a regulatory phospho-switch.

suggested_questions:
- question: How is TANK's dual behaviour - positive regulation of TBK1/IKKepsilon-driven
    type I interferon induction versus negative regulation of canonical NF-kappaB via
    the USP10/ZC3H12A deubiquitination complex - partitioned between stimuli, subcellular
    pools, and post-translational states (phosphorylation by IKBKE, SUMOylation)?
- question: Given that TANK, SINTBAD and NAP1 compete for the same site on TBK1 and
    occupy distinct subcellular locations, what determines which adaptor is used for
    a given TBK1-dependent output (antiviral IFN versus autophagy/selective autophagy)?
suggested_experiments:
- description: Stimulus-resolved interactome (AP-MS/proximity labeling) of endogenous
    TANK under viral/poly(I:C) stimulation versus genotoxic stress and IL-1 to map
    the switch between the TBK1-IKKepsilon kinase complex and the USP10-ZC3H12A deubiquitination
    complex.
- description: Separation-of-function mutants (TBK1-binding-deficient versus TRAF6/ZC3H12A-binding-deficient
    TANK) reconstituted into TANK-knockout cells to independently test the contribution
    of each scaffold function to type I IFN induction and NF-kappaB resolution.
