General annotation (Comments)

Function	Component of the peroxisomal protein import machinery. Together with PEX1, 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.8 Ref.9 Ref.10
Subunit structure	Interacts with PEX1; forms a high-molcular-mass heterooligomer in the cytosol. Interacts with PEX15; anchors PEX1-PEX6 heterooligomers to the peroxisomal membrane and mediates their association with the peroxisomal importomer. Ref.8 Ref.9 Ref.5
Subcellular location	Cytoplasm. Peroxisome membrane; Peripheral membrane protein; Cytoplasmic side. Note: Shuttles between the cytoplasm and the peroxisomal membrane. Ref.5 Ref.6
Domain	AAA-cassette D1 is required for interaction with PEX1. ATP-binding in AAA-cassette D1 is required for attachment to PEX15. ATP-binding and hydrolysis in AAA-cassette D2 is required for release from PEX15 and proper function in PEX5 dislocation.
Miscellaneous	Present with 1630 molecules/cell in log phase SD medium. Ref.7
Sequence similarities	Belongs to the AAA ATPase family.
