Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA-(3'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 5'-OH DNA strand. The free DNA strand then rotates around the intact phosphodiester bond on the opposing strand, thus removing DNA supercoils. Finally, in the religation step, the DNA 5'-OH attacks the covalent intermediate to expel the active-site tyrosine and restore the DNA phosphodiester backbone (By similarity). Regulates the alternative splicing of tissue factor (F3) pre-mRNA in endothelial cells. Involved in the circadian transcription of the core circadian clock component ARNTL\/BMAL1 by altering the chromatin structure around the ROR response elements (ROREs) on the ARNTL\/BMAL1 promoter.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eResearch_area\u003c\/b\u003e:Epigenetics and Nuclear Signaling\u003c\/p\u003e\u003cp\u003e\u003cb\u003eApplications\u003c\/b\u003e:ELISA\u003c\/p\u003e\u003cp\u003e\u003cb\u003eTarget_protein\u003c\/b\u003e:TOP1\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReactivity\u003c\/b\u003e:Human\u003c\/p\u003e\u003cp\u003e\u003cb\u003eAssay type\u003c\/b\u003e:Sandwich\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSensitivity\u003c\/b\u003e:0.12ng\/ml\u003c\/p\u003e\u003cp\u003e\u003cb\u003eDetection range\u003c\/b\u003e:0.2-70ng\/ml\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSample type\u003c\/b\u003e:Serum, plasma or other biological fluids\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFull product name\u003c\/b\u003e:Dna Topoisomerase 1\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSpecies\u003c\/b\u003e:Human\u003c\/p\u003e\u003cp\u003e\u003cb\u003eStorage\u003c\/b\u003e:2-8ºC\u003c\/p\u003e\u003cp\u003e\u003cb\u003eAssay time\u003c\/b\u003e:1h 30m\u003c\/p\u003e\u003cp\u003e\u003cb\u003eUniProt accession\u003c\/b\u003e:P11387\u003c\/p\u003e\u003cp\u003e\u003cb\u003eMASS(Da)\u003c\/b\u003e:90,726\u003c\/p\u003e\u003cp\u003e\u003cb\u003eGeneID\u003c\/b\u003e:7150\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSynonyms\u003c\/b\u003e:DNA topoisomerase 1;DNA topoisomerase I;TOP 1;TOP1\u003c\/p\u003e\u003cp\u003e\u003cb\u003eGene names\u003c\/b\u003e:TOP1\u003c\/p\u003e\u003cp\u003e\u003cb\u003eStandard solution\u003c\/b\u003e:80ng\/ml\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":39784231469156,"sku":"E3605Hu","price":603.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/products\/no_image_default_image-jpeg_daf6432a-19d5-4a14-b032-38e2b720e25a.jpg?v=1660515625","url":"https:\/\/www.genebiosystems.com\/en-gb\/products\/human-dna-topoisomerase-1-top1-elisa-kit","provider":"GeneBio ","version":"1.0","type":"link"}
