Peroxisome biogenesis factor 1, also known as PEX1, is a protein which in humans is encoded by the PEX1 gene.{{cite web | title = Entrez Gene: PEX1 peroxisome biogenesis factor 1| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=5189| access-date = }}

This gene encodes a member of the AAA protein family, a large group of ATPases associated with diverse cellular activities. This protein is cytoplasmic but is often anchored to a peroxisomal membrane where it forms a heteromeric complex and plays a role in the import of proteins into peroxisomes and peroxisome biogenesis. Mutations in this gene have been associated with complementation group 1 peroxisomal disorders such as neonatal adrenoleukodystrophy, infantile Refsum disease, and Zellweger syndrome.

Interactions

PEX1 has been shown to interact with PEX6{{cite journal | vauthors = Tamura S, Shimozawa N, Suzuki Y, Tsukamoto T, Osumi T, Fujiki Y | title = A cytoplasmic AAA family peroxin, Pex1p, interacts with Pex6p | journal = Biochemical and Biophysical Research Communications | volume = 245 | issue = 3 | pages = 883–886 | date = April 1998 | pmid = 9588209 | doi = 10.1006/bbrc.1998.8522 }}{{cite journal | vauthors = Geisbrecht BV, Collins CS, Reuber BE, Gould SJ | title = Disruption of a PEX1-PEX6 interaction is the most common cause of the neurologic disorders Zellweger syndrome, neonatal adrenoleukodystrophy, and infantile Refsum disease | journal = Proceedings of the National Academy of Sciences of the United States of America | volume = 95 | issue = 15 | pages = 8630–8635 | date = July 1998 | pmid = 9671729 | pmc = 21127 | doi = 10.1073/pnas.95.15.8630 | bibcode = 1998PNAS...95.8630G | doi-access = free }} and PEX26.{{cite journal | vauthors = Matsumoto N, Tamura S, Fujiki Y | title = The pathogenic peroxin Pex26p recruits the Pex1p-Pex6p AAA ATPase complexes to peroxisomes | journal = Nature Cell Biology | volume = 5 | issue = 5 | pages = 454–460 | date = May 2003 | pmid = 12717447 | doi = 10.1038/ncb982 | s2cid = 2426040 }}

Related diseases

Mutations in the genes encoding PEX1, along with PEX6, are the leading causes of peroxisomal biogenesis disorders,{{cite journal | vauthors = Waterham HR, Ebberink MS | title = Genetics and molecular basis of human peroxisome biogenesis disorders | journal = Biochimica et Biophysica Acta (BBA) - Molecular Basis of Disease | volume = 1822 | issue = 9 | pages = 1430–1441 | date = September 2012 | pmid = 22871920 | doi = 10.1016/j.bbadis.2012.04.006 | doi-access = free }} such as Zellweger Syndrome spectrum, infantile Refsum disease, and neonatal adrenoleukodystrophy. These genetic diseases are autosomal recessive and occur in 1 of every 50,000 births.{{cite journal | vauthors = Braverman NE, Raymond GV, Rizzo WB, Moser AB, Wilkinson ME, Stone EM, Steinberg SJ, Wangler MF, Rush ET, Hacia JG, Bose M | display-authors = 6 | title = Peroxisome biogenesis disorders in the Zellweger spectrum: An overview of current diagnosis, clinical manifestations, and treatment guidelines | journal = Molecular Genetics and Metabolism | volume = 117 | issue = 3 | pages = 313–321 | date = March 2016 | pmid = 26750748 | pmc = 5214431 | doi = 10.1016/j.ymgme.2015.12.009 }} Because of the autosomal recessive inheritance of Zellweger Syndrome, PEX1 is usually found in carrier screening gene panels. A very common PEX1 variant, Gly843Asp, is a mild allele well-reported in the literature.{{cite journal | vauthors = Braverman NE, D'Agostino MD, Maclean GE | title = Peroxisome biogenesis disorders: Biological, clinical and pathophysiological perspectives | journal = Developmental Disabilities Research Reviews | volume = 17 | issue = 3 | pages = 187–196 | date = June 2013 | pmid = 23798008 | doi = 10.1002/ddrr.1113 }}
