Anti-Topo II Alpha Recombinant Monoclonal

Topoisomerases regulate topological states of DNA and are divided into type I and type II enzymes. Type II topoisomerases make double stranded breaks in DNA and allow the passage of another duplex DNA across the break to achieve unknotting of entangled DNA. Topo II Alpha is one of two described isoforms that are likely products of a gene duplication event. TopoII Alpha is also described to be involved in chromosome condensation, chromatid separation, and the relief of supercoil stress. Protein function: Key decatenating enzyme that alters DNA topology by binding to two double-stranded DNA molecules, generating a double-stranded break in one of the strands, passing the intact strand through the broken strand, and religating the broken strand (PubMed:17567603, PubMed:18790802, PubMed:22013166, PubMed:22323612). May play a role in regulating the period length of ARNTL/BMAL1 transcriptional oscillation. [The UniProt Consortium]
