فراتاکسین (انگلیسی: Frataxin) یک پروتئین است که در انسان توسط ژن «FXN» کُدگذاری می‌شود.^[۴]^[۵]

فراتاکسین در میتوکندری جای دارد و عملکرد دقیق آن هنوز مشخص نیست، اما به نظر می‌رسد که در ساخت دسته‌جات ترکیبی آهن-سولفور نقش دارد. احتمال می‌رود که فراتاکسین یک شپرون آهن یا پروتئین ذخیره‌کننده آهن باشد.^[۶]

اهمیت بالینی

کاهش بیان فراتاکسین سبب بروز بیماری کشندهٔ آتاکسی فردریش می گردد.
