PEX1:PEX6:PEX26 (known as the Receptor Export Module) extracts ubiquitinated PEX5L from the peroxisomal membrane Docking and Translocation Module (Tamura et al. 2006, Tamura et al. 2014). PEX1 and PEX6 are soluble proteins that form a hexameric ring bound to PEX26 in the peroxisomal membrane (Matsumoto et al. 2003, Welle et al. 2005). ZFAND6 (AWP1) probably binds to ubiquitinated PEX5 and PEX6 and acts as an export factor (Miyata et al. 2012).
