Summary
This gene encodes an essential component of the peroxisomal import machinery. The protein is integrated into peroxisome membranes with its C-terminus exposed to the cytosol, and interacts with the cytosolic receptor for proteins containing a PTS1 peroxisomal targeting signal. The protein also functions as a transcriptional corepressor and interacts with a histone deacetylase. A mutation in this gene results in one form of Zellweger syndrome. [provided by RefSeq, Jul 2008]

  1. Data suggest that soluble/cytosolic PEX5 interacts with PEX14/PEX13 complex, a model for the docking/translocation module (DTM) of the peroxisomal matrix protein translocon; PEX14/PEX13 complex appears to function in peroxisomal membrane as large cavity into which cytosolic PEX5 can enter to release its cargo. (PEX = peroxisomal biogenesis factor)
    Title: The peroxisomal matrix protein translocon is a large cavity-forming protein assembly into which PEX5 protein enters to release its cargo.
  2. data reveal subpopulations of peroxisomes showing only weak colocalization between PEX14 and PEX5 or PEX11 but at the same time a clear compartmentalized organization. This compartmentalization, which was less evident in cases of strong colocalization, indicates dynamic protein reorganization linked to changes occurring in the peroxisomes.

  3. PEX14 is the 13th PEX gene responsible for peroxisome biogenesis disorders. Thus far, only two patients with PEX14 deficiency have been reported.
    Title: First Japanese case of Zellweger syndrome with a mutation in PEX14.
  4. The novel Pex14-binding site may represent the initial tethering site of Pex5 from which the cargo-loaded receptor is further processed in a sequential manner.

  5. interaction of PEX5 with catalase and PEX14
    Title: PEX5 protein binds monomeric catalase blocking its tetramerization and releases it upon binding the N-terminal domain of PEX14.
  6. PEX14 is a multi-tasking protein that not only facilitates peroxisomal protein import but is also required for peroxisome motility by serving as membrane anchor for microtubules.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
