UniProt Comments
Contributes to morphology determination of peroxisomes, but not to import of peroxisomal matrix proteins (PubMed:16923726, PubMed:17478547). Required for proper post-translational import and stabilization of peroxisomal membrane proteins (PMPs) (PubMed:16923726, PubMed:17478547). Acts as a cytosolic import receptor for PMPs and delivers them to the docking factor PEX3 at the peroxisomal membrane for subsequent insertion into the membrane (PubMed:17478547). Required for transport of APEM9 to peroxisome membranes (PubMed:21487094). Acts as a chaperone in stabilizing or maintaining PMPs in the lipid bilayer (PubMed:17478547).
