Involved in peroxisome biosynthesis. Required for stability of the PTS1 receptor. Anchored by PEX26 to peroxisome membranes, possibly to form heteromeric AAA ATPase complexes required for the import of proteins into peroxisomes. Interacts directly with PEX26 and PEX1. Mediates the indirect interaction between PEX1 and PEX26. Interacts with ZFAND6. Associated with peroxisomal membranes. Localized at the base of the outer segment of photoreceptor cells (PubMed:26593283). Expressed in the retina, at higher levels in the photoreceptor layer at the joint between the outer and inner segments. The disease is caused by variants affecting the gene represented in this entry.
