KW-1110 (Inhibition of host TRAFs by virus) — KW2GO remapping
Bottom line: UniProt keyword KW-1110 "Inhibition of host TRAFs by virus"
was mapped to GO:0039527, a process term GO has now obsoleted because
"TRAF-mediated signal transduction" is not a single pathway: TRAFs act in RLR,
TLR, TNFR and cGAS-STING signaling. The mapping has been repointed to
GO:0140476, which ties TRAF inhibition to cytoplasmic pattern recognition
receptor (RLR) signaling and matches the parent keyword KW-1113. As of
2026-09-26, OLS resolves GO:0140476 and marks GO:0039527 obsolete (suggesting
GO:0140476 or the TLR sibling GO:0140470), and the GO uniprotkb_kw2go file
(version date 2026/07/06) maps KW-1110 to GO:0140476. This page was a
watch-list entry, not a review project, and no gene review in this repository
carries GO:0039527, GO:0140476 or KW-1110, so nothing needs rework. The
"blocker" in the status section below predates these upstream changes.
We track it so that any viral or bacterial TRAF-interfering effector reviewed
later is moved to the right pathway-specific term rather than to the obsolete
parent.
Overview
Tracks a UniProt keyword-to-GO (KW2GO) mapping change proposed upstream: the
mapping from UniProt keyword KW-1110 "Inhibition of host TRAFs by virus" to
its current GO term is being moved to a more informative target that fits the
keyword's biology.
- Keyword: KW-1110 "Inhibition of host TRAFs by virus"
- Parent keyword: KW-1113 "Inhibition of host RLR pathway by virus"
Current mapping (to be removed)
| GO ID | Label |
|---|---|
| GO:0039527 | symbiont-mediated suppression of host TRAF-mediated signal transduction |
- OLS lookup confirms this label. GO:0039527 is itself queued for obsoletion via
geneontology/go-ontology#29238
because "TRAF-mediated signal transduction" is not a real pathway on the
ontology's process branch (TRAFs act in many downstream pathways: TLR,
TNF/TNFR, cGAS-STING, RLR, etc.).
Proposed replacement mapping (to be added)
| GO ID | Label |
|---|---|
| GO:0140476 | symbiont-mediated suppression of host cytoplasmic pattern recognition receptor signaling pathway via inhibition of TRAF activity |
- Superseded (2026-09-26): GO:0140476 now resolves in OLS and the GO
uniprotkb_kw2gofile maps KW-1110 to it (see the bottom line above). The
rest of this item is the historical record: on 2026-07-04 the term ID did not
yet resolve in OLS, and per the annotation tracker discussion, the term still needed to be created in
the ontology before the KW-1110 mapping could be repointed at it. The
annotation tracker ticket was waiting on confirmation before deleting the
existing mapping and adding the new one (the deletion was reversible if the
new term was delayed).
Nature of the change
Lateral / more-specific move within the same "symbiont-mediated suppression of
host signaling" branch. The proposed target explicitly ties TRAF-inhibition to
the cytoplasmic pattern recognition receptor (PRR) signaling pathway family
(RIG-I / MDA5 / LGP2 → MAVS → TBK1 / IRF3 / NF-κB), which matches the parent
keyword KW-1113 "Inhibition of host RLR pathway by virus". Reviewers on the
upstream thread note that TRAF is used by TLRs, TNFR, and cGAS-STING as well,
so this new target is a better fit for the specifically viral / RLR context
that KW-1110 sits under, but it does not cover TRAF interference by bacteria
or by viral proteins that act via TLR or TNFR routes — those need their own
child terms if the ontology decides to model them (see the upstream comments
by @genegodbold and @pgaudet for candidate templates).

Impact on this repo
No gene reviews currently touch either identifier.
Searches performed on 2026-07-04:
grep -rl "0039527" genes— no gene review files match (only a false-positive
substring hit inside an Ensembl ID in a cached UniProt record).grep -rl "0140476" genes— no matches (as expected: term not yet created).grep -rl "KW-1110" genes— no matches.
So this repo has no reviews that will need to be rewritten when the mapping
lands. The purpose of this project page is therefore purely to remember to
re-check once the ontology change and mapping change ship, not to queue
existing rework.
Follow-up
- Watch go-ontology#29238
and go-annotation#6470
for term creation and mapping deployment. - Once GO:0140476 (or whatever ID the new term receives) is created and the
KW-1110 mapping is repointed, re-run the two greps above to catch any newly
added reviews for viral effector genes carrying KW-1110 (e.g. EBV BPLF1,
FMDV Lb(pro), HSV-1 ICP0, SARS-CoV-2 M, and the bacterial TRAF-interfering
effectors listed in the go-ontology thread). - If any of those viral / bacterial effector genes enter this repo later,
theirexisting_annotationsreview should MODIFY away from GO:0039527 and
toward the new PRR-signaling target when the annotation actually carries
evidence for a cytoplasmic-PRR context; TLR or TNFR contexts should go to
the appropriate sibling term instead (see @pgaudet's per-effector
assignments in go-ontology#29238).
Status
- Created: 2026-07-04
- Blocker: GO:0140476 not yet minted; KW2GO deployment blocked on that.
- Update 2026-09-26: OLS shows GO:0140476 minted and GO:0039527 obsolete
(consider GO:0140476 or GO:0140470). Re-ran the three greps: still no matches in
genes/. The GOexternal2go/uniprotkb_kw2gofile (version date 2026/07/06)
maps KW-1110 to GO:0140476, so the mapping change has shipped. - Action needed here: none until upstream ships. This page is a watch-list
entry so the mapping change is not silently missed when it lands.
