• function: [Isoform 3]: Component of a topoisomerase 6 complex specifically required for meiotic recombination. Together with SPO11, mediates DNA cleavage that forms the double-strand breaks (DSB) that initiate meiotic recombination. The complex promotes relaxation of negative and positive supercoiled DNA and DNA decatenation through cleavage and ligation cycles.
  subunit: [Isoform 3]: Heterotetramer of SPO11 and 2 TOP6BL chains. Interacts with SPO11.

• Leveraging electronic health records to study pleiotropic effects on bipolar disorder and medical comorbidities.
  Prieto, Translational psychiatry 2016
  • GeneRIF: Top association findings suggested that the bipolar disorder risk allele at SNP rs10896235 in C11orf80 may be associated with increased risk of headache, including migraine.

TO6BL_MOUSE / J3QMY9 Type 2 DNA topoisomerase 6 subunit B-like; TOP6B like initiator of meiotic double strand breaks; Type 2 DNA topoisomerase VI subunit B-like; TOPOVIBL from Mus musculus (Mouse) (see paper)
Aligns to 120:573 / 579 (78.4%), covers 100.0% of PF15091, 818.7 bits

• function: Component of a topoisomerase 6 complex specifically required for meiotic recombination. Together with SPO11, mediates DNA cleavage that forms the double-strand breaks (DSB) that initiate meiotic recombination. The complex promotes relaxation of negative and positive supercoiled DNA and DNA decatenation through cleavage and ligation cycles.
  subunit: Heterotetramer of SPO11 and 2 TOP6BL chains (Probable). Interacts with SPO11 (PubMed:26917764).
  disruption phenotype: Male mice develop normally and reach adulthood but have smaller testes. Spermatogonia are present at the periphery of tubules but are strongly depleted and spermatids are absent, due to defects during meiotic prophase.
