Biophys. Res. Commun. 262:504-508(1999). CC -!- FUNCTION: Binds to the C-terminal PTS1-type tripeptide peroxisomal CC targeting signal (SKL-type) and plays an essential role in CC peroxisomal protein import. CC -!- SUBUNIT: Interacts with PEX7 and PEX13 (By similarity). Interacts CC with PEX12 and PEX14. CC -!- INTERACTION: CC O00623:PEX12; NbExp=2; IntAct=EBI-597835, EBI-594836; CC -!- SUBCELLULAR LOCATION: Cytoplasm. Peroxisome; peroxisomal membrane; CC peripheral membrane protein. Note=Its distribution appears to be CC dynamic. It is probably a cycling receptor found mainly in the CC cytoplasm and as well associated to the peroxisomal membrane CC through a docking factor (PEX13). CC -!- ALTERNATIVE PRODUCTS: CC Event=Alternative splicing; Named isoforms=3; CC Name=1; CC IsoId=P50542-1; Sequence=Displayed; CC Name=2; CC IsoId=P50542-2; Sequence=VSP_021880; CC Name=3; CC IsoId=P50542-3; Sequence=VSP_024106; CC -!- TISSUE SPECIFICITY: Detected in heart, brain, placenta, lung, CC liver, skeletal muscle, kidney and pancreas. CC -!- DISEASE: Defects in PEX5 are a cause of neonatal CC adrenoleukodystrophy (NALD) [MIM:202370]. NALD is a peroxisome CC biogenesis disorder characterized by the accumulation of very CC long-chain fatty acids, adrenal insufficiency and mental CC retardation. Inheritance is autosomal recessive. CC -!- DISEASE: Defects in PEX5 are a cause of Zellweger syndrome (ZWS) CC [MIM:214100]. ZWS is a fatal peroxisome biogenesis disorder CC associated with severe abnormalities in the brain, liver and CC kidney. Death occurs soon after birth. CC -!- DISEASE: Defects in PEX5 may be a cause of infantile Refsum CC disease (IRD) [MIM:266510]. IRD is a mild peroxisome biogenesis CC disorder. Clinical features include early onset, mental CC retardation, minor facial dysmorphism, retinopathy, sensorineural CC hearing deficit, hepatomegaly, osteoporosis, failure to thrive, CC and hypocholesterolemia. The biochemical abnormalities include CC accumulation of phytanic acid, very long chain fatty acids CC (VLCFA), di- and trihydroxycholestanoic acid and pipecolic acid. CC -!- SIMILARITY: Belongs to the peroxisomal targeting signal receptor CC family. CC -!- SIMILARITY: Contains 7 TPR repeats.
