Gene Description

RNF14 (E3 ubiquitin-protein ligase RNF14; legacy name ARA54, androgen receptor-associated protein 54) is a cytosolic, ribosome-associated RING-in-between-RING (RBR)-type E3 ubiquitin ligase (EC 2.3.2.31). It contains an N-terminal RWD domain and a C-terminal TRIAD/RBR module (RING1, IBR, atypical RING2) and works with E2 enzymes of the UBE2D/UBE2E families. Its principal characterized function is in the RNF14-RNF25 translational quality-control pathway acting on stalled and collided ribosomes. Recruited to stalled ribosomes by the ribosome-collision sensor GCN1, RNF14 catalyzes atypical Lys-6 (K6)-linked ubiquitination of translation factors eEF1A (EEF1A1) and eRF1 (ETF1) and of ribosomal proteins, marking them for proteasomal degradation. It is specifically required to resolve reactive-aldehyde (e.g. formaldehyde)-induced RNA-protein crosslinks that stall ribosomes, by K6-ubiquitinating the crosslinked species for extraction by the VCP/p97 unfoldase and subsequent degradation. Independently of this co-translational surveillance role, RNF14 also acts in the nucleus as a transcriptional coregulator. It promotes Wnt/TCF-beta-catenin-mediated transcription via interaction with TCF7/TCF7L1/TCF7L2, and acts as a coactivator for androgen- (and to a lesser extent progesterone-) dependent transcription via interaction with the androgen receptor. It is widely expressed and undergoes RING-dependent autoubiquitination.

GO Term Evidence Action Reason
GO:0031624 ubiquitin conjugating enzyme binding
IBA
GO_REF:0000033 		ACCEPT
Summary: As an RBR-type E3 ligase, RNF14 binds E2 ubiquitin-conjugating enzymes (UBE2E1/UBE2E2 experimentally; UBE2D family via interactome). E2 binding is mechanistically required for its ligase activity.
Reason: Directly supported by documented interaction with the E2 enzymes UBE2E1/UBE2E2 and consistent with the RBR catalytic mechanism (E2 binds RING1, trans-thiolation to the RING2 active-site cysteine). This supports, but is subordinate to, the core ubiquitin ligase activity.

Summary: RNF14 functions as the catalytic E3 within the RNF14-RNF25 ubiquitin ligase machinery that acts on stalled ribosomes, consistent with being part of a ubiquitin ligase complex.
Reason: RNF14 is an E3 ligase that operates in concert with RNF25 and GCN1 on stalled ribosomes; the ubiquitin ligase complex localization is appropriate.

Suggested Questions for Experts

Q: What determines RNF14 substrate selection (eEF1A vs eRF1 vs ribosomal proteins vs RNA-protein crosslinks) on stalled ribosomes, and how is this coordinated with RNF25?

Q: Is the nuclear transcriptional coregulator role (AR/Wnt) mechanistically dependent on RNF14 ligase activity, or is it a ligase-independent scaffolding function?

Q: How is the choice of K6-linked chain topology achieved by the atypical RBR module that lacks the canonical RING2 histidine?

Suggested Experiments

Experiment: Ribosome profiling and quantitative ubiquitin-site proteomics in RNF14 and RNF14/RNF25 double knockouts after formaldehyde or stalling stress to map the full K6-ubiquitinated substrate set.

Experiment: Structure-function analysis (cryo-EM of RNF14-GCN1-stalled ribosome complexes) to define how GCN1 recruits and positions RNF14 on collided ribosomes.

Experiment: Separation-of-function mutants (catalytic-dead Cys-417/Cys-220 vs AR/TCF-binding-deficient C-terminal mutants) to test whether the transcriptional moonlighting roles require ligase activity.

Core function (RNF14-RNF25 translation QC)

RNF14 is the E3 ligase of the RNF14-RNF25 translation quality control pathway that acts on
stalled ribosomes. Recruited by the ribosome collision sensor GCN1, RNF14 catalyzes atypical
K6-linked ubiquitination of translation factors (eEF1A/EEF1A1 and eRF1/ETF1) and ribosomal
proteins on stalled ribosomes, leading to their degradation. It is specifically required to
resolve reactive-aldehyde (e.g. formaldehyde)-induced RNA-protein crosslinks (RPCs) that stall
ribosomes, by K6-ubiquitinating the crosslinks for VCP-dependent extraction and proteasomal
degradation.

Legacy androgen receptor / Wnt roles (ARA54)

RNF14/ARA54 was originally described as an androgen-receptor coactivator (PMID:10085091,
PMID:19345326) and later a regulator of TCF/beta-catenin (Wnt) transcription and colon cancer
survival (PMID:23449499). UniProt: "Independently of its function in the response to stalled
ribosomes, acts as a regulator of transcription in Wnt signaling ... May also play a role as a
coactivator for androgen- and ... progesterone-dependent transcription."

AIGR Review Snapshot

  • Description: RNF14 (E3 ubiquitin-protein ligase RNF14; legacy name ARA54, androgen receptor-associated protein 54) is a cytosolic, ribosome-associated RING-in-between-RING (RBR)-type E3 ubiquitin ligase (EC 2.3.2.31). It contains an N-terminal RWD domain and a C-terminal TRIAD/RBR module (RING1, IBR, atypical RING2) and works with E2 enzymes of the UBE2D/UBE2E families. Its principal characterized function is in the RNF14-RNF25 translational quality-control pathway acting on stalled and collided ribosomes.

PN Consistency Summary

  • Consistency: Excellent. Deep research, review and PN concur: RBR-type E3 (RWD + TRIAD/RING1-IBR-RING2), GCN1-recruited, K6-linked ubiquitination of eEF1A/eRF1 on stalled ribosomes, plus reactive-aldehyde RNA-protein crosslink resolution (GO:0160127), and the AR/Wnt nuclear moonlighting role (kept non-core). The PN correctly distinguishes the catalytic ligase MF (GO:0061630 at the RBR group) from process. No contradictions.
  • PN story / NEW pressure: GO:0061630 (verified real), GO:0016567 — both already in GOA + review (multiple IDA, Cys-220/Cys-417 mutagenesis). GO:0006515 (verified real) is new_to_goa; RNF14 genuinely acts in stalled-ribosome QC so it is a defensible higher-level ADD, but broader than the review's precise set (GO:0072344, GO:0085020 K6, GO:0160127, GO:0006511). Conclude: ligase MF + ubiquitination already captured; GO:0006515 defensible-but-broader ADD.
  • Evidence alignment: PN RBR row cites "PMID 17367545 / rev" — this PMID is NOT in the review's references. Review's RQC evidence (PMID:36638793, 37651229, 37951215/16, 27863242) is HIGH/VERIFIED and richer than the PN row. Divergence: the single PN-cited RBR PMID is uncited in the review (likely an older RBR-family review; low impact since ligase MF is independently well-supported).
  • Verdict: Fully consistent; PN ligase MF (GO:0061630) and ubiquitination already captured, GO:0006515 a defensible-but-broader ADD. No YAML change needed.

Conclude: ligase MF + ubiquitination already captured; GO:0006515 defensible-but-broader ADD.
  • Mapping strategy: Correctly resolves RNF14 as the catalytic ligase (GO:0061630), not a generic UBD reader — group-level mapping appropriate; subtype/type no_mapping avoids double-counting. RQC-group→GO:0006515 broader than terms already present. No node change warranted.

PN row 1: Translation | Cytosolic translation | Ribosome-associated QC | ubiquitination of eEF1A on stalled ribosomes

  • UniProt: Q9UBS8
  • In branches: TR, UPS
  • PN-node mapping records (path + ancestors):
    • [type] Translation|Cytosolic translation|Ribosome-associated QC|ubiquitination of eEF1A on stalled ribosomes
      status=mapped scope=ok_for_propagation_to_go GO=[GO:0016567 protein ubiquitination]
      rationale: This PN RQC type is a specific ubiquitination bucket for eEF1A on stalled ribosomes. Protein ubiquitination is the shared process target.
    • [group] Translation|Cytosolic translation|Ribosome-associated QC
      status=mapped scope=ok_for_propagation_to_go GO=[GO:0006515 protein quality control for misfolded or incompletely synthesized proteins]
      rationale: The PN ribosome-associated quality-control group covers surveillance and disposal of stalled or defective nascent-chain translation products. GO lacks a dedicated ribosome-associated QC term in the local cache, so the broader protein-quality-control process is the best supported target.
    • [class] Translation|Cytosolic translation
      status=context_only scope=too_broad_to_propagate GO=[GO:0002181 cytoplasmic translation]
      rationale: The PN class Cytosolic translation is centered on the cytoplasmic translation apparatus and process, but it also houses supporting machinery such as ribosome biogenesis factors. The GO process term is a useful high-level label for the class, but propagating it to all members would over-annotate genes whose PN placement is through assembly or maturation context rather than core cytoplasmic translation.
    • [branch] Translation
      status=context_only scope=too_broad_to_propagate GO=[GO:0006412 translation]
      rationale: The PN Translation branch is organized around the translation apparatus and immediately associated cotranslational quality-control systems. GO translation is the closest high-level process label, but the PN branch also contains adjacent machinery such as ribosome biogenesis and nascent-chain handling. Keeping this relationship is useful for interpretation, but it is too broad to project safely onto every member.

  review:
    summary: As an RBR-type E3 ligase, RNF14 binds E2 ubiquitin-conjugating enzymes (UBE2E1/UBE2E2 experimentally; UBE2D family via interactome). E2 binding is mechanistically required for its ligase activity.
    action: ACCEPT
    reason: Directly supported by documented interaction with the E2 enzymes UBE2E1/UBE2E2 and consistent with the RBR catalytic mechanism (E2 binds RING1, trans-thiolation to the RING2 active-site cysteine). This supports, but is subordinate to, the core ubiquitin ligase activity.

suggested_questions:
- question: What determines RNF14 substrate selection (eEF1A vs eRF1 vs ribosomal proteins vs RNA-protein crosslinks) on stalled ribosomes, and how is this coordinated with RNF25?
- question: Is the nuclear transcriptional coregulator role (AR/Wnt) mechanistically dependent on RNF14 ligase activity, or is it a ligase-independent scaffolding function?
- question: How is the choice of K6-linked chain topology achieved by the atypical RBR module that lacks the canonical RING2 histidine?
