Gene: TOP3A (DNA topoisomerase III alpha) Homo sapiens
Analyze
Symbol: TOP3A
Name: DNA topoisomerase III alpha
RGD ID: 1319604
Description: Exhibits DNA topoisomerase type I (single strand cut, ATP-independent) activity and single-stranded DNA binding activity. Involved in DNA topological change; chromosome separation; and mitochondrial DNA metabolic process. Localizes to PML body. Implicated in autosomal recessive progressive external ophthalmoplegia with mitochondrial DNA deletions 5.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: DNA topoisomerase 3-alpha; MGRISCE2; PEOB5; TOP3; topo III-alpha; topoisomerase (DNA) III alpha; ZGRF7; zinc finger, GRF-type containing 7
