WebOct 13, 2024 · Pex3p can be classified as a peroxin essential for the assembly of peroxisome membranes. Very recently, Pex16p and Pex19p were also shown to function in assembly of peroxisome vesicles in mammals (Honsho et al., 1998; Matsuzono et al., 1999; South and Gould, 1999), as was the case for Pex19p in yeast (Snyder et al., 1999).
