Fxn Protein — Frataxin plays an important role in the study of neurodegenerative diseases. This page provides comprehensive information about this topic, including its mechanisms, significance in disease processes, and therapeutic implications.
Frataxin is a mitochondrial protein encoded by the FXN gene (also known as the frataxin gene). It is essential for mitochondrial iron-sulfur cluster (Fe-S) biosynthesis and plays a critical role in cellular energy metabolism. Reduced frataxin levels cause Friedreich's ataxia, a progressive neurodegenerative disorder.
