| 产品介绍 | background: 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.

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 (By similarity). 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.

文献和实验相关实验
特异性的选择主要需要考虑四个方面：蛋白特异性、种属特异性、实验方法特异性、标记物的特异性。 （1）蛋白特异性 针对需要检测的蛋白查找抗体，几个细节要区分，重组表达的蛋白和内源性蛋白的检测，对抗体的要求是不一样的，注意查看抗体说明书的检测说明。如果重组蛋白不是全长表达，则需要注意抗体的免疫原区域是否在重组蛋白区域内。内源性蛋白最好能清楚其剪切与修饰的方式，特殊表型的蛋白需要进行序列比对，并结合抗体免疫原序列，查看交叉反应的情况。磷酸化蛋白检测需要确定具体位点，不同位点的磷酸化意味
，促使细胞合成和释放生物活性物质，引发Ⅰ型超敏反应。由抗体引起的免疫损伤可见于I、II、III型超敏反应和自身免疫病。
在生命科学和医学基础研究中，或多或少都需要用到抗体。抗体的应用场景不同、标记物众多，且针对同一标记物市场上往往有多个抗体可供选择，那么，我们如何从成百万上千万种抗体中，挑选出我们想要的那支呢？ 在我们6月份的关于抗体的调研活动中，我们发现，大家更多的是去参考文献或专利中的材料和方法部分，这无疑很大程度上保证了抗体的有效性。其次有45%和34%的受访者会用到百度和谷歌，然而这两个搜索引擎覆盖面颇广，经常会出现抗体无关的搜索结果，而专业用于查找抗体的网站，大家却知之甚少。 因此，本次文章中
