CC -!- FUNCTION: Necessary for early peroxisomal biogenesis. Acts both as a
CC cytosolic chaperone and as an import receptor for peroxisomal membrane
CC proteins (PMPs). Binds and stabilizes newly synthesized PMPs in the
CC cytoplasm by interacting with their hydrophobic membrane-spanning
CC domains, and targets them to the peroxisome membrane by binding to the
CC integral membrane protein PEX3. Excludes CDKN2A from the nucleus and
CC prevents its interaction with MDM2, which results in active degradation
CC of TP53. {ECO:0000250|UniProtKB:P40855}.
CC -!- SUBUNIT: Interacts with a broad range of peroxisomal membrane proteins,
CC including PEX3, PEX10, PEX11A, PEX11B, PEX12, PEX13, PEX14 and PEX16,
CC PXMP2/PMP22, PXMP4/PMP24, SLC25A17/PMP34, ABCD1/ALDP, ABCD2/ALDRP, and
CC ABCD3/PMP70. Also interacts with the tumor suppressor CDKN2A/p19ARF (By
CC similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P40855}.
CC Peroxisome membrane {ECO:0000250|UniProtKB:P40855}; Lipid-anchor
CC {ECO:0000250|UniProtKB:P40855}; Cytoplasmic side
CC {ECO:0000250|UniProtKB:P40855}. Note=Mainly cytoplasmic. Some fraction
CC membrane-associated to the outer surface of peroxisomes.
CC {ECO:0000250|UniProtKB:P40855}.
CC -!- SIMILARITY: Belongs to the peroxin-19 family. {ECO:0000305}.
