Pex5 is a receptor which binds with peroxisomal-targeting sequence proteins in the cytosol that protein targeted into the peroxisomal matrix by forming a multimeric complex with the Pex14 receptor located on the peroxisomal membrane. After assembly, the matrix protein dissociates from Pex5 and Pex5 is then returned to the cytosol by which process?
