General annotation (Comments)

Function	Component of the peroxisomal protein import machinery. 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, where it is then available for another round of protein import into the organelle. Ref.6 Ref.7 Ref.8
Subunit structure	Interacts with PEX6; forms a high-molcular-mass heterooligomer in the cytosol. The PEX1-PEX6 heterooligomers associate with the peroxisomal importomer via interaction of PEX6 with the peroxisomal membrane anchor PEX15. Ref.6 Ref.7 Ref.8
Subcellular location	Cytoplasm. Peroxisome membrane; Peripheral membrane protein; Cytoplasmic side. Note: Shuttles between the cytoplasm and the peroxisomal membrane. Ref.4
Induction	By oleate.
Domain	AAA-cassette D1 is required for interaction with PEX6. ATP-binding in AAA-cassette D2 is required for interaction with PEX6. ATP-binding and hydrolysis in AAA-cassette D2 is required for proper function in PEX5 dislocation.
Miscellaneous	Present with 2100 molecules/cell in log phase SD medium. Ref.5
Sequence similarities	Belongs to the AAA ATPase family.
