Peroxisome biogenesis factor 1, also known as PEX1, is a protein which in humans is encoded by the PEX1 gene. [5]
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. [5]
PEX1 has been shown to interact with PEX6 [6] [7] and PEX26. [8]
Mutations in the genes encoding PEX1, along with PEX6, are the leading causes of peroxisomal biogenesis disorders, [9] 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. [10] 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. [11]
