These enzymes regμlate the topology of DNA, maintain genomic integrity, and are essential for processes such as DNA replication, recombination, transcription, and chromosome segregation by allowing DNA strands to pass through each other. Topoisomerase I nicks and rejoins one strand of the duplex DNA, while topoisomerase II transiently breaks and closes double-stranded DNA . Topoisomerases are very susceptible to various stresses. Acidic pH or oxidative stress can convert topoisomerases to DNA-breaking nucleases, causing genomic instability and cell death. DNA-damaging topoisomerase targeting drugs (e.g., etoposide) also convert topoisomerases to nucleases, with the enzyme usually trapped as an intermediate that is covalently bound to the 5+ end of the cleaved DNA strand(s). Research studies have shown that this intermediate leads to genomic instability and cell death. Thus, agents that target topoisomerases are highly sought after cancer chemotherapeutic drugs. Ca2+-regμlated phosphorylation of topoisomerase IIα at Ser1106 modμlates the activity of this enzyme and its sensitivity to targeting drugs.\u003c\/p\u003e\n\n\u003cp\u003eCategory: Primary Antibody\u003c\/p\u003e\n\n\u003cp\u003eReactivity: Human\u003c\/p\u003e\n\n\u003cp\u003eHost: Rabbit\u003c\/p\u003e\n\n\u003cp\u003eApplications: WB\u003c\/p\u003e\n\n\u003cp\u003eAlternate Names: TOP2, DNA topoisomerase 2-alpha, DNA topoisomerase II alpha isozyme\u003c\/p\u003e\n\n\u003cp\u003eClonality: Polyclonal\u003c\/p\u003e\n\n\u003cp\u003eConjugate: Unconjugated\u003c\/p\u003e\n\n\u003cp\u003eModification: Phosphorylation\u003c\/p\u003e\n\n\u003cp\u003eImmunogen: KLH-conjugated synthetic peptide encompassing a sequence within the C-term region of human Topoisomerase 2 alpha with a site at pS1213.
