PTS1R is a peroxisomal targeting sequence involved in the specific transport of molecules for oxidation inside the peroxisome. SKL binds to PTS1R in the cytosol followed by binding to the Pex14p receptor allowing importation of the peroxisomal protein through the pexsubunit transporter.

Diseases associated with dysfunctional PTS1R receptors include X-linked adrenoleukodystrophy and Zellweger syndrome.

Interactions

PEX5 has been shown to interact with PEX12,[6][7] PEX13[8][9] and PEX14.[7][9][10]
