Description
Predicted to enable DNA helicase activity and single-stranded DNA binding activity. Predicted to be involved in mitochondrial DNA replication. Predicted to act upstream of or within DNA replication. Predicted to be active in mitochondrion. Is expressed in brain. Human ortholog(s) of this gene implicated in Perrault syndrome; autosomal dominant progressive external ophthalmoplegia with mitochondrial DNA deletions 3; chronic progressive external ophthalmoplegia; and mitochondrial DNA depletion syndrome 7. Orthologous to human TWNK (twinkle mtDNA helicase).
