Peroxisomal import receptor that mediates the peroxisomal import of both malate synthases MLS1 and MLS2 in oleate-grown cells (PubMed:27678487, PubMed:27663510). Recognizes the C-terminal peroxisomal targeting signal PTS1 sequence SKL of MLS1 and MLS2, probably via its TPR domains (PubMed:27678487). Interacts with the PTS1-receptor docking protein PEX14 but not with peroxins PEX1, PEX3 through to PEX8, PEX10, PEX11, PEX12, PEX13, PEX15, PEX17, PEX18, PEX19 and PEX21 (PubMed:27678487). Interacts the PTS1-receptor docking protein PEX14 (PubMed:27678487). Interacts with malate synthases MLSL1 and MLS2 (PubMed:27678487). Interacts with TLG1 (PubMed:11283351). Expression is induced by oleate. The WxxxF motif is involved in the interaction with the PTS1-receptor docking protein PEX14. The TPR repeats are involved in the interaction with the C-terminal peroxisomal targeting signal PTS1 of MLS1 and MLS2. Leads to a clear mislocalization of both MLS1 and MLS2 to the cytosol. Belongs to the peroxisomal targeting signal receptor family.
