TWNK (Twinkle mtDNA helicase) encodes a mitochondrial DNA helicase essential for mitochondrial DNA replication. [@van2003]
Gene Overview
Function
TWNK is a mitochondrial DNA helicase that unwinds double-stranded mtDNA during replication.
Normal Function
mtDNA replication: Helicase activity essential for replication fork progression
mtDNA maintenance: Prevents mtDNA deletions
Mitochondrial function: Maintains proper mtDNA copy number
Disease Associations
Mitochondrial Disorders
Neurodegeneration Links
