Peroxins (or peroxisomal/peroxisome biogenesis factors) represent several protein families found in peroxisomes.{{cite journal | vauthors = Crookes WJ, Olsen LJ | title = Peroxin puzzles and folded freight: peroxisomal protein import in review | journal = Die Naturwissenschaften | volume = 86 | issue = 2 | pages = 51–61 | date = February 1999 | pmid = 10084148 | doi = 10.1007/s001140050572 | bibcode = 1999NW.....86...51C | hdl = 2027.42/41882 | s2cid = 22119827 | hdl-access = free }} Deficiencies are associated with several peroxisomal disorders. 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. Some of them were predicted to be single-pass transmembrane proteins, for example Peroxisomal biogenesis factor 11.
