| 产品介绍 | DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. 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 Pol II. A bridging helix emanates from RPB1 and crosses the cleft near the catalytic site and is thought to promote translocation of Pol II by acting as a ratchet that moves the RNA-DNA hybrid through the active site by switching from straight to bent conformations at each step of nucleotide addition. During transcription elongation, Pol II moves on the template as the transcript elongates. Elongation is influenced by the phosphorylation status of the C-terminal domain (CTD) of Pol II largest subunit (RPB1), which serves as a platform for assembly of factors that regulate transcription initiation, elongation, termination and mRNA processing. Acts as a RNA-dependent RNA polymerase when associated with small delta antigen of Hepatitis delta virus, acting both as a replicate and transcriptase for the viral RNA circular genome. Function: DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. 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.

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.

Elongation is influenced by the phosphorylation status of the C-terminal domain (CTD) of Pol II largest subunit (RPB1), which serves as a platform for assembly of factors that regulate transcription initiation, elongation, termination and mRNA processing. Acts as a RNA-dependent RNA polymerase when associated with small delta antigen of Hepatitis delta virus, acting both as a replicate and transcriptase for the viral RNA circular genome. Subunit: Component of the RNA polymerase II (Pol II) complex consisting of 12 subunits. The phosphorylated C-terminal domain interacts with FNBP3 and SYNCRIP. Interacts with SAFB/SAFB1. Interacts with CCNL1 and MYO1C (By similarity). Interacts with CCNL2 and SFRS19. Component of a complex which is at least composed of HTATSF1/Tat-SF1, the P-TEFb complex components CDK9 and CCNT1, RNA polymerase II, SUPT5H, and NCL/nucleolin. Interacts with PAF1. Interacts (via C-terminus) with FTSJD2, CTDSP1 and SCAF8. Interacts via the phosphorylated C-terminal domain with WDR82 and with SETD1A and SETD1B only in the presence of WDR82. Interacts with ATF7IP. When phosphorylated at 'Ser-5', interacts with MEN1; the unphosphorylated form, or phosphorylated at 'Ser-2' does not interact. Subcellular Location: Nucleus. Post-translational modifications: Dephosphorylated by the protein phosphatase CTDSP1. Ubiquitinated by WWP2 leading to proteasomal degradation. Methylated at Arg-1810 by CARM1. Methylation occurs only when the CTD is hypophosphorylated, and phosphorylation at Ser-1805 and Ser-1808 prevent methylation (in vitro). It is assumed that methylation occurs prior to phosphorylation and transcription initiation. CTD methylation may facilitate the expression of select RNAs. Similarity: Belongs to the RNA polymerase beta' chain family.

文献和实验一般是指 DNA依存性 RNA聚合酶。是催化以 DNA为模板( template)、三磷酸核糖核苷为底物、通过磷酸二酯键而聚合的合成 RNA的酶。因为在细胞内与基因 DNA的遗传信息转录为 RNA有关,所以也称转录酶。反应以下式示: n1 -n4 表示各个模板的 DNA链的胸腺嘧啶、胞嘧啶、鸟嘧啶、腺嘌呤的碱基数。通过特异的碱基配对的形成,合成具有与模板 DNA链完全互补的碱基排列的 RNA。反应是由( 1) DNA与酶的结合
的RNA合成体系全部被T4的合成体系所取代。 RNA聚合酶 在感染后的前6分钟,T7噬菌体的RNAPol尚未表达,因此仍使用了宿主E.coli的RNA聚合酶,转录的基因主要有10个(0.3,0.4,0.5,0.6,0.65,0.7,1,1.1,1.2,1.3),其0.3基因编码宿主限制酶的抑制蛋白,使T7进入宿主免遭降解;0.7基因编码一种蛋白激酶,能将E.coli的RNA聚合酶磷酸化,为抑制宿主RNAPol作准备;基因1编码T7RNAPol聚合酶,分子量为98
An RNA Polymerase II In Vitro Transcription System
A great deal of attention in recent years has been focused on the mechanisms governing transcription. Repression and/or activation of specific genes, or sets of genes, represents a key regulatory step in such diverse processes as cell growth
