What is "peroxin"

n. (context protein English) Any of a family of proteins, found in peroxisomes, that are associated with several peroxisomal disorders

Peroxin (or peroxisomal/peroxisome biogenesis factor) is a protein found in peroxisomes.

Deficiencies are associated with several peroxisomal disorders.

Numerous peroxin proteins 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.
