Decatenation Assays and Topo II – Supercoiled pBR322 Provided by TopoGEN

Decatenation Assays and Topo II – Supercoiled pBR322 Provided by TopoGEN

A non-canonical function of topoisomerase II  in disentangling dysfunctional telomeres Thomas Germe, Kyle Miller1 and  Julia Promisel Cooper Telomere Biology Laboratory, Cancer Research, London, UK The decatenation activity of topoisomerase II (Top2), which is widely conserved within the eukaryotic domain, is essential for chromosomal segregation in mitosis.  It is less clear, however, whether Top2 performs the same function uniformly across the whole genome, and whether all its functions rely on decatenation.  In the fission yeast, Schizosaccharomyces pombe, telomeres are bound…
