Short name: Pex1

Overlapping homologous superfamilies


Family relationships



Peroxisome biogenesis factor 1, also known as peroxin-1 or PEX1, is a component of the peroxisomal protein import machinery. In addition to its role in import, PEX1 together with PEX6, mediates the ATP-dependent relocation and recycling of the peroxisomal targeting signal-1 (PTS1) import receptor PEX5 from the peroxisomal membrane to the cytosol [PMID: 15634331, PMID: 16007078, PMID: 16911527].
