RNA topoisomerase is prevalent in all domains of life and associates with polyribosomes in animals [PDF]
DNA Topoisomerases are essential to resolve topological problems during DNA metabolism in all species. However, the prevalence and function of RNA topoisomerases remain uncertain.

Clinical Significance of Expression of Topoisomerase 2а in Breast Cancer
Topoisomerases are enzymes that control the topology of DNA. Topoisomerases are divided into types 1 and 2, depending on the mechanism of action. The article discusses the structure and mechanisms of the action of topoisomerases, the possibility of an ...

Topological Process of Splitting DNA-Links
A DNA replicon is modeled by a special type of 2-component link, called a DNA-link, in which two circles form a double helix around a trivial center core curve.

Topoisomerase IV can functionally replace all type 1A topoisomerases in Bacillus subtilis
DNA topoisomerases play essential roles in chromosome organization and replication. Most bacteria possess multiple topoisomerases which have specialized functions in the control of DNA supercoiling or in DNA catenation/decatenation during recombination ...

Structural insights into the gating of DNA passage by the topoisomerase II DNA-gate. [PDF]
Type IIA topoisomerases (Top2s) manipulate the handedness of DNA crossovers by introducing a transient and protein-linked double-strand break in one DNA duplex, termed the DNA-gate, whose opening allows another DNA segment to be transported through to ...

Roles of Topoisomerases in Heterochromatin, Aging, and Diseases
Heterochromatin is a transcriptionally repressive chromatin architecture that has a low abundance of genes but an enrichment of transposons. Defects in heterochromatin can cause the de-repression of genes and transposons, leading to deleterious ...

The newfound relationship between extrachromosomal DNAs and excised signal circles
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...
