Functional role of the AAA peroxins in dislocation of the cycling PTS1 receptor back to the cytosol.

Abstract excerpt

Peroxisomal import receptors bind their cargo proteins in the cytosol and target them to docking and translocation machinery at the peroxisomal membrane (reviewed in ref. 1). The receptors release the cargo proteins into the peroxisomal lumen and, according to the model of cycling receptors, they are supposed to shuttle back to the cytosol. This shuttling of the receptors has been assigned to peroxins including...
