The product of this gene contains a carboxy terminal domain composed of heptapeptide repeats that are essential for polymerase activity. These repeats contain serine and threonine residues that are phosphorylated in actively transcribing RNA polymerase. In addition, this subunit, in combination with several other polymerase subunits, forms the DNA binding domain of the polymerase, a groove in which the DNA template is transcribed into RNA.

Largest and catalytic component of RNA polymerase II which synthesizes mRNA precursors and many functional non-coding RNAs. Forms the polymerase active center together with the second largest subunit. Pol II is the central component of the basal RNA polymerase II transcription machinery. It is composed of mobile elements that move relative to each other. RPB1 is part of the core element with the central large cleft, the clamp element that moves to open and close the cleft and the jaws that are thought to grab the incoming DNA template. At the start of transcription, a single stranded DNA template strand of the promoter is positioned within the central active site cleft of\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSpecies:\u003c\/b\u003e Human;Mouse;Rat;Monkey\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRange:\u003c\/b\u003e WB;IHC;IF;ELISA\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eProtein:\u003c\/b\u003e DNA-directed RNA polymerase II subunit RPB1\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDA:\u003c\/b\u003e 250kD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Upingbio","offers":[{"title":"100UL","offer_id":50689867710744,"sku":"YP-Ab-01384-100UL","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/images_4b0ddf84-d329-4fa5-af03-e2bb834556dd.png?v=1758591695","url":"https:\/\/danabiosci.com\/products\/yp-ab-01384-100ul","provider":"Dana Bioscience","version":"1.0","type":"link"}
