PEO1 (also known as TWNK or Twinkle) is a mitochondrial DNA helicase essential for mitochondrial DNA (mtDNA) replication[1]. Mutations in PEO1 cause mitochondrial DNA depletion syndromes and have been implicated in neurodegenerative diseases[2].
The PEO1 gene encodes a 684-amino acid hexameric helicase:
PEO1 is expressed in high-energy tissues:
The study of Peo1 Gene Twinkle Mitochondrial Dna Helicase has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
