General name for products of the PEX genes that are essential for peroxisome biogenesis. At least 29 are known and molecular defects have been defined in 10 PEX genes, 8 related to protein import and 2 related to membrane synthesis. For example, peroxin 1 encodes one of the AAA family, peroxin 5 encodes the receptor that recognizes the peroxisomal targeting signal PTS1. See peroxisome biogenesis disorders.
