Summary
PEX26 (peroxisomal biogenesis factor 26, HGNC:22965) is a protein-coding gene on chromosome 22q11.21, encoding Peroxisome assembly protein 26 (Q7Z412). Peroxisomal docking factor that anchors PEX1 and PEX6 to peroxisome membranes.
This gene belongs to the peroxin-26 gene family. It is probably required for protein import into peroxisomes. It anchors PEX1 and PEX6 to peroxisome membranes, possibly to form heteromeric AAA ATPase complexes required for the import of proteins into peroxisomes. Defects in this gene are the cause of peroxisome biogenesis disorder complementation group 8 (PBD-CG8). PBD refers to a group of peroxisomal disorders arising from a failure of protein import into the peroxisomal membrane or matrix. The PBD group is comprised of four disorders: Zellweger syndrome (ZWS), neonatal adrenoleukodystrophy (NALD), infantile Refsum disease (IRD), and classical rhizomelic chondrodysplasia punctata (RCDP). Alternatively spliced transcript variants have been identified for this gene.

Literature-anchored findings (GeneRIF, showing 13)
- degree of temperature sensitivity in pex26 cell lines is predictive of the clinical phenotype in patients with PEX26 deficiency (PMID:12851857)
- PEX26 deficiency impairs peroxisomal import of both PTS1- and PTS2-targeted matrix proteins. It undergoes alternative splicing to produce several splice forms, including PEX26-delta, which rescues peroxisome biogenesis in PEX26-deficient cells. (PMID:15858711)
- Pex26p functions in recruiting to peroxisomes the complexes of the AAA ATPase peroxins. (PMID:16257970)
- We analyzed targeting of human PEX26. Its C-terminal-targeting signal contains two binding sites for PEX19 and we conclude C-terminal PEX19-binding sites mark tail-anchored proteins for delivery to peroxisomes. (PMID:16763195)
- the relative fraction of disease-causing alleles that occur in the coding and splice junction sequences of PEX26 gene. (PMID:19105186)
- PEX19 formed a complex with the peroxisomal tail anchored protein PEX26 in the cytosol and translocated it directly to peroxisomes by a TRC40-independent class I pathway. (PMID:23460677)
- results suggested that peroxisome biogenesis requires Pex1p- and Pex6p-regulated dissociation of Pex14p from Pex26p (PMID:25016021)
- In yeast, PEX26 follows the pathway that also ensures correct targeting of Pex15: PEX26 enters the endoplasmic reticulum (ER) in a GET-dependent and Pex19-independent manner. (PMID:26627908)
- Data support an alternative PEX14-dependent mechanism of peroxisomal membrane association for the splice variant, which lacks a transmembrane domain. Structure-function relationships of PEX26 isoforms explain an extended function in peroxisomal homeostasis and these findings may improve our understanding of the broad phenotype of PEX26-associated human disorders. (PMID:30366024)
- An autosomal recessive missense variant, c.153C>A (p.F51L) in PEX26 was identified in Ashkenazi Jewish individual with a milder form of Zellweger spectrum and hearing loss. Binding of Pex26-F51L to Pex1 and Pex6 is severely impaired and affects peroxisome assembly. Pex26 in the patient’s fibroblasts is reduced to approximately 30% of control, suggesting that Pex26-F51L is unstable in cells. There are also other changes… (PMID:30446579)
- There are no significant differences between PEX1-, PEX6-, and PEX26-associated phenotypes inclinical and genetic spectrum of Heimler syndrome. (PMID:31831025)
- Silencing PEX26 as an unconventional mode to kill drug-resistant cancer cells and forestall drug resistance. (PMID:34074205)

All UniProt accessions (3): A0A024R100, A0A0S2Z5M7, Q7Z412
UniProt curated annotations — full annotation on UniProt →
Function. Peroxisomal docking factor that anchors PEX1 and PEX6 to peroxisome membranes. PEX26 is therefore required for the formation of the PEX1-PEX6 AAA ATPase complex, a complex that mediates the extraction of the PEX5 receptor from peroxisomal membrane.
Subunit / interactions. Interacts (via its cytoplasmic domain) with PEX6; interaction is direct and is ATP-dependent. Interacts with PEX1; interaction is indirect and is mediated via interaction with PEX6.
Subcellular location. Peroxisome membrane.
Tissue specificity. Widely expressed. Highly expressed in kidney, liver, brain and skeletal muscles. Expressed at intermediate level in pancreas, placenta and heart. Weakly expressed in lung.
Disease relevance. Peroxisome biogenesis disorder complementation group 8 (PBD-CG8) [MIM:614872] A peroxisomal disorder arising from a failure of protein import into the peroxisomal membrane or matrix. The peroxisome biogenesis disorders (PBD group) are genetically heterogeneous with at least 14 distinct genetic groups as concluded from complementation studies. Include disorders are: Zellweger syndrome (ZWS), neonatal adrenoleukodystrophy (NALD), infantile Refsum disease (IRD), and classical rhizomelic chondrodysplasia punctata (RCDP). ZWS, NALD and IRD are distinct from RCDP and constitute a clinical continuum of overlapping phenotypes known as the Zellweger spectrum (PBD-ZSS). The disease is caused by variants affecting the gene represented in this entry. Peroxisome biogenesis disorder 7A (PBD7A) [MIM:614872] A fatal peroxisome biogenesis disorder belonging to the Zellweger disease spectrum and clinically characterized by severe neurologic dysfunction with profound psychomotor retardation, severe hypotonia and neonatal seizures, craniofacial abnormalities, liver dysfunction, and biochemically by the absence of peroxisomes. Additional features include cardiovascular and skeletal defects, renal cysts, ocular abnormalities, and hearing impairment. Most severely affected individuals with the classic form of the disease (classic Zellweger syndrome) die within the first year of life. The disease is caused by variants affecting the gene represented in this entry. Peroxisome biogenesis disorder 7B (PBD7B) [MIM:614873] A peroxisome biogenesis disorder that includes neonatal adrenoleukodystrophy (NALD) and infantile Refsum disease (IRD), two milder manifestations of the Zellweger disease spectrum. The clinical course of patients with the NALD and IRD presentation is variable and may include developmental delay, hypotonia, liver dysfunction, sensorineural hearing loss, retinal dystrophy and vision impairment. Children with the NALD presentation may reach their teens, while patients with the IRD presentation may reach adulthood. The clinical conditions are often slowly progressive in particular with respect to loss of hearing and vision. The biochemical abnormalities include accumulation of phytanic acid, very long chain fatty acids (VLCFA), di- and trihydroxycholestanoic acid and pipecolic acid. The disease is caused by variants affecting the gene represented in this entry.
