What do Peroxins do?
Peroxins serve several functions including the recognition of cytoplasmic proteins that contain peroxisomal targeting signals PTS that tag them for transport by peroxisomal proteins to the peroxisome. Peroxins are structurally diverse and have been classified to different protein families. Peroxin Wikipedia
