Synthesis pass · prose summary of the discoveries below

VPS13B is a large peripheral membrane protein that functions as a lipid transfer bridge at multiple organellar contact sites, maintaining Golgi ribbon integrity, facilitating ER-to-Golgi transport, and promoting mitochondrial fission. It localizes to the cis-trans Golgi interface where it is recruited by RAB6-GTP and by Sec23IP at ERES-Golgi contacts via its VAB domain; loss of VPS13B causes Golgi fragmentation, failure to form tubular ERGIC carriers, impaired procollagen secretion, and defective neurite outgrowth (PMID:21865173, PMID:25492866, PMID:39352497, PMID:39331042). VPS13B also localizes to Mitofusin 2-positive mitochondria where it delivers PI4P-rich Golgi-derived vesicles to fission sites, enabling DRP1-independent membrane scission; its loss produces elongated mitochondria with reduced membrane potential and impaired mitophagy (PMID:41402289). Biallelic loss-of-function mutations in VPS13B cause Cohen syndrome, an autosomal recessive disorder characterized by intellectual disability, microcephaly, joint laxity, and retinal dystrophy, phenotypes recapitulated in knockout mouse models showing microcephaly, motor and cognitive deficits, and cataracts (PMID:12730828, PMID:37573958, PMID:32915983).

    Super-resolution imaging refined VPS13B localization to the cis-trans Golgi interface and identified FAM177A1 as a physical interactor whose loss phenocopies VPS13B deficiency, while comprehensive KO mouse analysis revealed microcephaly, neuroanatomical changes, and infantile neuronal death — establishing both a new binding partner and the developmental window of VPS13B requirement.

    Evidence Super-resolution microscopy, BFA-washout Golgi reformation assay, co-IP, zebrafish genetic interaction, KO mouse 2D/3D brain morphometry and behavioral testing

    • In vivo validation of procollagen trafficking defect in animal models lacking
  8. 2025 High

    VPS13B was shown to localize to MFN2-positive mitochondria and deliver PI4P-rich Golgi vesicles to mitochondrial fission sites, enabling membrane scission independently of DRP1 constriction; this established VPS13B as a lipid transfer protein linking Golgi and mitochondrial biology and explained the elongated mitochondria and impaired mitophagy in Cohen syndrome.

    Evidence Live-cell imaging, mitochondrial morphology and membrane potential measurements, mitophagy assays, PI4P depletion, DRP1 recruitment assay, C-terminal domain mapping, patient iPSC-derived neurons

    PMID:41730960

    Open questions at the time
    • Mechanism by which VPS13B sorts CXADR away from lysosomes not defined
    • Whether this trafficking role is direct or secondary to Golgi disruption unclear
    • Single study, awaits independent confirmation

Open questions

Synthesis pass · forward-looking unresolved questions
  • Key unresolved questions include whether VPS13B functions as a bona fide lipid transfer channel (no in vitro reconstitution exists), how its multiple organellar localizations are coordinately regulated, and which specific VPS13B functions — Golgi maintenance, ER-Golgi transport, or mitochondrial fission — are primarily responsible for neurodevelopmental pathology in Cohen syndrome.
  • No in vitro lipid transfer reconstitution with purified VPS13B
  • No high-resolution structure of full-length VPS13B or its lipid-binding channel
  • Relative pathogenic contribution of Golgi vs. mitochondrial vs. trafficking defects to Cohen syndrome phenotypes not resolved

Sequence analysis, homology to yeast Vps13, gene characterization American journal of human genetics Low 12730828
2011 COH1/VPS13B is a peripheral Golgi membrane protein that co-localizes with the cis-Golgi matrix protein GM130; RNAi-mediated depletion causes fragmentation of the Golgi ribbon into ministacks, and Golgi fragmentation is also observed in fibroblasts from Cohen syndrome patients.

2014 COH1/VPS13B physically interacts with the active GTP-bound form of RAB6 at the Golgi complex; RAB6A/A' knockdown prevents COH1 Golgi localization, constitutively inactive RAB6_T27N increases solubilization of COH1 from membranes, and co-IP confirms preferential interaction with constitutively active RAB6_Q72L. COH1 depletion in primary neurons impairs neurite outgrowth, linking Golgi integrity to axonal outgrowth.

2023 VPS13B localizes at the interface between proximal and distal Golgi subcompartments (cis-trans interface); VPS13B KO cells show delayed Golgi complex reformation after Brefeldin A-induced disruption. VPS13B physically interacts with FAM177A1, a Golgi protein whose loss phenocopies VPS13B KO delay. In zebrafish, vps13b genetically interacts with fam177a1. Super-resolution microscopy, BFA-washout Golgi reformation assay, co-IP/interaction studies, zebrafish genetic interaction The Journal of cell biology High 39331042
2024 VPS13B is recruited to ER exit site (ERES)-Golgi interfaces by the adaptor protein Sec23IP via direct interaction through the VPS13 adaptor binding (VAB) domain. This interaction promotes ERES-Golgi association. Disease-associated missense mutations in VPS13B-VAB impair Sec23IP binding. Loss of VPS13B or Sec23IP blocks formation of tubular ERGIC (an unconventional ER-to-Golgi cargo carrier) and delays ER export of procollagen, linking VPS13B function to joint laxity in Cohen syndrome patients.

2023 VPS13B localizes to and promotes formation of Golgi-lipid droplet membrane contact sites (MCSs) upon oleic acid stimulation; depletion of VPS13B moderately reduces Golgi-LD contact formation in addition to causing Golgi fragmentation. 3D high-resolution microscopy, oleic acid stimulation, VPS13B depletion Contact (Thousand Oaks) Low 38090145
2025 VPS13B localizes to Mitofusin 2-positive mitochondria via its C-terminal region and recruits phosphatidylinositol-4-phosphate (PI4P)-rich Golgi vesicles to mitochondrial fission sites. Loss of VPS13B (including in Cohen syndrome patient-derived neurons) causes abnormally elongated/fused mitochondria with reduced membrane potential and impaired mitophagy. Loss of VPS13B or depletion of PI4P results in incomplete mitochondrial fission despite normal DRP1 recruitment, indicating VPS13B-mediated lipid transfer is required for membrane fission. Live-cell imaging, mitochondrial morphology assays, membrane potential measurements, mitophagy assays, PI4P depletion, DRP1 recruitment assay, patient iPSC-derived neurons, C-terminal domain localization mapping Nature communications High 41402289
2021 A VPS13B missense variant (c.710G>C, p.Arg237Pro) shows diminished localization at the Golgi complex by immunofluorescence, establishing that Golgi targeting is functionally relevant for VPS13B and that specific missense mutations disrupt this localization. Functional characterization of missense variant, immunofluorescence Golgi localization assay Frontiers in neuroscience Medium 39723426
2026 VPS13B regulates intracellular trafficking of the tight junction protein coxsackievirus and adenovirus receptor (CXADR) in gingival epithelial cells; VPS13B knockout causes decreased cell-surface CXADR and increased lysosomal CXADR degradation (bafilomycin A1 rescue), leading to increased epithelial permeability to LPS and PGN. The C-terminus of CXADR (not JAM1) is required for VPS13B-dependent trafficking.
