Gene names
Name:TOP2

Ordered Locus Names:YNL088W
ORF Names:N2244
OrganismSaccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Taxonomic identifier559292 [NCBI]
Taxonomic lineageEukaryota › Fungi › Dikarya › Ascomycota › Saccharomycotina › Saccharomycetes › Saccharomycetales › Saccharomycetaceae › Saccharomyces

Protein attributes

Sequence length1428 AA.
Sequence statusComplete.
Protein existenceEvidence at protein level

General annotation (Comments)

Function

Control of topological states of DNA by transient breakage and subsequent rejoining of DNA strands. Topoisomerase II makes double-strand breaks. Essential during mitosis and meiosis for proper segregation of daughter chromosomes.

Catalytic activity

ATP-dependent breakage, passage and rejoining of double-stranded DNA.

Subunit structure

Homodimer.

Subcellular location

Nucleus.

Post-translational modification

Phosphorylation enhances the activity. Stimulates decatenation activity.

Miscellaneous

In yeast topoisomerase II can substitute topoisomerase I for the relaxing activity.

Eukaryotic topoisomerase I and II can relax both negative and positive supercoils, whereas prokaryotic enzymes relax only negative supercoils.

Present with 5730 molecules/cell in log phase SD medium. Ref.7

Sequence similarities

Belongs to the type II topoisomerase family.
