Gene Description

CHMP5 encodes a SNF7-family ESCRT-III-associated regulatory protein that links LIP5/VTA1 to VPS4-dependent ESCRT-III recycling during endosomal multivesicular body sorting. CHMP5 is primarily cytosolic but functions at endosomal ESCRT assemblies, where CHMP5-LIP5/VTA1 interactions help tune VPS4 activation/disassembly and support MVB cargo sorting and lysosomal degradation of membrane proteins such as EGFR. Broader ESCRT contexts including cytokinesis, nuclear-envelope sealing, plasma membrane repair, viral budding, and autophagy are biologically plausible but secondary; infection-specific evidence supports CHMP5 involvement in anti-Shigella autophagy rather than a general CHMP5-specific autophagosome maturation mechanism.

The mechanistic refinement is that CHMP5 binds LIP5/VTA1 and helps regulate VPS4 activation/disassembly of ESCRT-III rather than acting as a CHMP4/Snf7-like primary filament/scission subunit.
GO:0032511 late endosome to vacuole transport via multivesicular body sorting pathway
IBA
GO_REF:0000033
MODIFY
Summary: The MVB-sorting essence is correct, but the human CHMP5 annotation should use the direct MVB sorting term.
Reason: CHMP5 is core to MVB sorting, but this vacuole-transport phrasing is less appropriate for a human protein than multivesicular body sorting pathway or the downstream late endosome-to-lysosome route.

Summary: Viral budding is not a core CHMP5 cellular function and is likely over-annotated here: viral budding from plasma membrane.
Reason: The key CHMP5/LIP5 study found CHMP5 depletion increased infectious HIV-1 release and concluded that only LIP5 is required for HIV release, so viral-budding annotations should not be treated as CHMP5 core function.

Core Functions

CHMP5 is an ESCRT-III-associated regulatory component for endosomal multivesicular body sorting and ESCRT-III recycling. Through a high-affinity CHMP5-LIP5/VTA1 interaction, CHMP5 helps assemble or tune LIP5/VPS4 activity on ESCRT-III substrates, supporting MVB cargo sorting, ESCRT-III complex disassembly, and downstream lysosomal degradation of ubiquitinated/endocytosed cargo relevant to proteostasis.

  • Local synthesis identifies CHMP5-LIP5/VTA1-VPS4 regulation of ESCRT-III recycling plus MVB sorting as core, with viral, nuclear-envelope, cytokinesis, repair, NOD2, and infection/autophagy contexts treated as secondary or over-annotated where appropriate.

Suggested Questions for Experts

Q: Can endogenous CHMP5 depletion/rescue separate its direct LIP5/VTA1-VPS4 regulatory role from pathway-level ESCRT-III membrane-fission annotations?

Q: Which CHMP5-specific autophagy annotations are supported by direct autophagosome closure or maturation assays rather than by ESCRT complex membership?

Q: Should viral-budding annotations for CHMP5 be replaced by a regulatory or non-core context, given evidence that CHMP5 depletion increases HIV-1 release while LIP5 is required?

Suggested Experiments

Experiment: Perform acute endogenous CHMP5 depletion and rescue with wild-type, LIP5-binding-defective, and ESCRT-tail mutant CHMP5 while measuring EGFR degradation, MVB ILV cargo sorting, and VPS4 recruitment/disassembly dynamics.

Hypothesis: CHMP5 rescue of MVB cargo degradation will require its LIP5/VTA1 interaction and will primarily affect VPS4-mediated ESCRT-III recycling rather than initial cargo recognition.

Experiment: Test CHMP5 recruitment and requirement in starvation autophagy, mitophagy, and xenophagy assays using direct reporters for unsealed autophagosomes and autolysosome formation.

Hypothesis: CHMP5 will contribute to autophagic clearance through endolysosomal/MVB function and pathogen-specific xenophagy contexts, but may not be a general autophagosome sealing effector.

Experiment: Compare CHMP5 and LIP5 knockdown/rescue in HIV-1 budding assays while quantifying MVB cargo degradation in parallel.

Hypothesis: CHMP5 perturbation will distinguish MVB sorting from viral release, supporting curation of viral budding as non-core or over-annotated for CHMP5.

Working synthesis

CHMP5 (UniProt Q9NZZ3) is a SNF7/ESCRT-III family protein best treated as an ESCRT-III regulatory component for endosomal MVB sorting and VPS4/LIP5-mediated ESCRT-III recycling. UniProt describes CHMP5 as a "Probable peripherally associated component" of ESCRT-III involved in MVB formation and sorting of endosomal cargo into MVBs, with ILVs delivered to lysosomes for degradation of membrane proteins such as stimulated growth factor receptors [UniProt:Q9NZZ3 "involved in multivesicular bodies (MVBs) formation and sorting of endosomal cargo proteins into MVBs"; UniProt:Q9NZZ3 "enabling degradation of membrane proteins, such as stimulated growth factor receptors"].

The most direct CHMP5-specific cellular evidence is Ward et al. 2005: CHMP5 is a LIP5-binding protein, is mainly cytosolic, and CHMP5 RNAi reduces EGFR degradation without grossly disrupting early endosomes, lysosomes, or Golgi. That paper concludes that LIP5 and CHMP5 function in MVB sorting, while only LIP5 is required for HIV release [PMID:15644320 "We identify CHMP5 as a LIP5-binding protein and show that CHMP5 is primarily cytosolic."; PMID:15644320 "CHMP5 depletion results in an increase in the release of infectious HIV-1 particles."; PMID:15644320 "both LIP5 and CHMP5 function in MVB sorting, whereas only LIP5 is required for HIV release."].

The mechanistic refinement is that CHMP5 binds LIP5/VTA1 and helps regulate VPS4 activation/disassembly of ESCRT-III rather than acting as a CHMP4/Snf7-like primary filament/scission subunit. Shim et al. 2008 confirm high-affinity LIP5-CHMP5 binding and suggest CHMP5-bound LIP5 may regulate engagement of other ESCRT-III proteins and VPS4 [PMID:18385515 "LIP5 binds preferentially to soluble CHMP5"; PMID:18385515 "CHMP5 bound to LIP5 might negatively regulate LIP5 for engagement with other ESCRT-III proteins and VPS4"]. Skalicky et al. 2012 show that LIP5 binds a novel MIM element in CHMP5, and that stable VPS4 complexes with LIP5 and CHMP5 require LIP5 to bind both a MIM1-containing ESCRT-III protein and CHMP5 [PMID:23105106 "the second LIP5 MIT module binds with unusually high affinity to a novel MIM element within the ESCRT-III protein CHMP5"; PMID:23105106 "promoting assembly of active VPS4 enzymes on the polymeric ESCRT-III substrate"].

Proteostasis-network context: CHMP5 supports endolysosomal degradation through ESCRT/MVB sorting, so MVB sorting, MVB assembly, ubiquitin-dependent protein catabolism via MVB sorting, late endosome-to-lysosome transport, and ESCRT-III disassembly are core or near-core PN-relevant terms. General ESCRT autophagy literature shows that functional MVBs are required for autophagic clearance of aggregate-prone proteins, but the cached CHMP5 GOA autophagy annotations mostly derive from ESCRT-complex context rather than CHMP5-specific autophagosome sealing assays [PMID:17984323 "Functional multivesicular bodies are required for autophagic clearance"; PMID:17984323 "functional MVBs are required to prevent accumulation of abnormal proteins"]. A Shigella infection study provides CHMP5-specific anti-bacterial autophagy evidence, but it is infection context: IcsB modifies CHMP5 and CHMP5 knockout affects S. flexneri escape from host autophagy PMID:30061757.

Secondary ESCRT contexts should generally be kept as non-core. Broad ESCRT-III papers support roles in cytokinetic abscission, centrosome/spindle maintenance, nuclear envelope sealing, plasma membrane repair, and viral budding, but they should not override the CHMP5-specific MVB/VPS4-LIP5 regulatory function [PMID:20616062 "depletion of VPS4A, VPS4B, or any of the 11 different human ESCRT-III (CHMP) proteins inhibited abscission"; PMID:26040713 "ESCRT-III controls nuclear envelope reformation"; PMID:24482116 "repair of certain wounds is ensured by ESCRT-mediated extracellular shedding of wounded portions"].

The NOD2/LPS/MDP annotations are not core CHMP5 function. Thiebaut et al. identify CHMP5 as a NOD2-interacting protein and report induction by MDP/LPS, but the study itself says these new interacting proteins did not appear to be major NOD2-dependent NF-kappaB regulators in the assay [PMID:27812135 "the primary interaction was confirmed by coimmunoprecipitation and/or bioluminescence resonance energy transfer (BRET) experiments for 11 of these proteins"; PMID:27812135 "none of the NIPs isolated here, except RICK, appear to be major regulators of the NOD2 dependent NF-kappaB pathway"].

Curation decisions

  • Core: ESCRT-III complex membership, MVB sorting/assembly, ubiquitin-dependent cargo degradation through MVB sorting, ESCRT-III disassembly/recycling via LIP5/VTA1 and VPS4, and the endolysosomal degradation route that follows MVB sorting.
  • Non-core: cytosol/nucleus/exosome locations, midbody/cytokinesis, spindle/centrosome, nuclear envelope/pore reassembly, plasma membrane repair, infection/autophagy contexts, and viral budding.
  • Over-annotated: generic protein binding, cadherin binding, viral budding as a CHMP5 function, and LPS/MDP response terms inferred from induction or interaction context rather than a demonstrated CHMP5 response function.
  • Modify: vacuolar transport and vesicle fusion/MVB-lysosome fusion terms should be represented as MVB sorting or late endosome-to-lysosome transport.

Deep research status

just deep-research-falcon human CHMP5 timed out after 600 seconds and reported that all providers failed. No CHMP5-deep-research-falcon.md file was written, so this review is based on UniProt, GOA-seeded annotations, cached publications, and the local synthesis above.

Description cleanup note

The YAML description field was revised to keep it as a standalone biological summary. Project-specific curation framing moved here instead.

  • Moved out of the YAML description: the Proteostasis Network framing interpreted CHMP5 as an endolysosomal cargo-sorting and ESCRT-recycling component, with broader ESCRT contexts treated as secondary.

AIGR Review Snapshot

  • Description: CHMP5 encodes a SNF7-family ESCRT-III-associated regulatory protein that links LIP5/VTA1 to VPS4-dependent ESCRT-III recycling during endosomal multivesicular body sorting. CHMP5 is primarily cytosolic but functions at endosomal ESCRT assemblies, where CHMP5-LIP5/VTA1 interactions help tune VPS4 activation/disassembly and support MVB cargo sorting and lysosomal degradation of membrane proteins such as EGFR. Broader ESCRT contexts including cytokinesis, nuclear-envelope sealing, plasma membrane repair, viral budding, and autophagy are biologically plausible but secondary; infection-specific evidence supports CHMP5 involvement in anti-Shigella autophagy rather than a general CHMP5-specific autophagosome maturation mechanism.

PN Consistency Summary

  • Consistency: Consistent. The review frames CHMP5 not as a polymerizing core subunit but as a SNF7-family ESCRT-III-associated regulator that links LIP5/VTA1 to VPS4 disassembly. Its description explicitly says evidence does not support a "general CHMP5-specific autophagosome maturation mechanism." PN's component-bucket placement and the review's regulatory framing are compatible; the review is appropriately more cautious than the PN's blanket "ESCRT-III complex component" label.
  • PN story / NEW pressure: PN projects GO:0000045 autophagosome assembly (verified real). CHMP5 support is family/regulatory-inheritance only (autophagosome maturation is IEA/GO_REF:0000117, KEEP_AS_NON_CORE). A gene-specific GO:0000045 assertion would be over-reach; the review already captures the autophagy context as non-core and asks (suggested_question) which CHMP5 autophagy annotations rest on direct closure/maturation assays. PN over-reaches for CHMP5 — already captured; do not ADD.
  • Evidence alignment: Divergent. PN cites only the Cells "Key Regulators of Autophagosome Closure" review. Review cites primary ESCRT/regulatory literature (incl. PMID:36107470 ESCRT-III-MIT interactome [verified, not the PN review], PMID:17984323). No shared specific citations; same broad theme.
  • Verdict: Consistent; review appropriately conservative on the PN autophagy projection. Recommended edits: none.

    supporting_text: The mechanistic refinement is that CHMP5 binds LIP5/VTA1 and helps regulate VPS4 activation/disassembly
      of ESCRT-III rather than acting as a CHMP4/Snf7-like primary filament/scission subunit.

    supporting_text: CHMP5 (UniProt Q9NZZ3) is a SNF7/ESCRT-III family protein best treated as an ESCRT-III regulatory component
      for endosomal MVB sorting and VPS4/LIP5-mediated ESCRT-III recycling.

suggested_questions:
- question: Can endogenous CHMP5 depletion/rescue separate its direct LIP5/VTA1-VPS4 regulatory role from pathway-level ESCRT-III
    membrane-fission annotations?
- question: Which CHMP5-specific autophagy annotations are supported by direct autophagosome closure or maturation assays
    rather than by ESCRT complex membership?
- question: Should viral-budding annotations for CHMP5 be replaced by a regulatory or non-core context, given evidence that
    CHMP5 depletion increases HIV-1 release while LIP5 is required?
suggested_experiments:
- description: Perform acute endogenous CHMP5 depletion and rescue with wild-type, LIP5-binding-defective, and ESCRT-tail
    mutant CHMP5 while measuring EGFR degradation, MVB ILV cargo sorting, and VPS4 recruitment/disassembly dynamics.
  hypothesis: CHMP5 rescue of MVB cargo degradation will require its LIP5/VTA1 interaction and will primarily affect VPS4-mediated
    ESCRT-III recycling rather than initial cargo recognition.
- description: Test CHMP5 recruitment and requirement in starvation autophagy, mitophagy, and xenophagy assays using direct
    reporters for unsealed autophagosomes and autolysosome formation.
  hypothesis: CHMP5 will contribute to autophagic clearance through endolysosomal/MVB function and pathogen-specific xenophagy
    contexts, but may not be a general autophagosome sealing effector.
- description: Compare CHMP5 and LIP5 knockdown/rescue in HIV-1 budding assays while quantifying MVB cargo degradation in
    parallel.
  hypothesis: CHMP5 perturbation will distinguish MVB sorting from viral release, supporting curation of viral budding as
    non-core or over-annotated for CHMP5.
