Peroxisomal docking factor that anchors PEX1 and PEX6 to peroxisome membranes (PubMed:12717447, PubMed:12851857, PubMed:16257970, PubMed:16763195, PubMed:16854980, PubMed:21362118). PEX26 is therefore required for the formation of the PEX1-PEX6 AAA ATPase complex, a complex that mediates the extraction of the PEX5 receptor from peroxisomal membrane (PubMed:12717447, PubMed:12851857, PubMed:16257970, PubMed:16763195, PubMed:16854980, PubMed:21362118). {ECO:0000269|PubMed:12717447, ECO:0000269|PubMed:12851857, ECO:0000269|PubMed:16257970, ECO:0000269|PubMed:16763195, ECO:0000269|PubMed:16854980, ECO:0000269|PubMed:21362118}. This is the function of PEX26 (peroxisomal biogenesis factor 26, ENSG00000215193).
