It is encoded by a single PGR gene residing on chromosome 11q22. The PR gene uses separate promoters and translational start sites to produce 2 isoforms, PRA and PRB, which are identical except for an additional 165 amino acids present only in the N terminus of PRB. It can be observed in human breast tissues. The proteins function as dimeric molecules in nuclei to regulate the transcription of target genes in a ligand-responsive manner.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"100 ug","offer_id":51550466146584,"sku":"R31442","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_9fe726a6-e5fe-4071-883d-96df7a2f8005.jpg?v=1768314865","url":"https:\/\/danabiosci.com\/products\/nsj-r31442-100ug","provider":"Dana Bioscience","version":"1.0","type":"link"}
