产品介绍 : responsible for the synthesis of a different class of RNA. RNA polymerase I (Pol I) transcribes the rRNA (ribosomal RNA) genes for the precursor of the 28S, 18S, and 5.8S molecules of the ribosome. RNA polymerase II transcribes protein-encoding genes into mRNA (messenger RNA) and snRNA (small nuclear RNA) genes into snRNAs that influence the processing of other classes of RNA. RNA polymerase III (Pol III) transcribes the 5S rRNA genes and all of the tRNA (transfer RNA) genes. Each class of RNA polymerase is assembled from 9 to 15 different polypeptides. The RPB6 and RPB8 subunits are shared by all 3 RNA polymerases.
Function:
General activator of RNA polymerase which utilizes different TFIIIB complexes at structurally distinct promoters. The isoform 1 is involved in the transcription of tRNA, adenovirus VA1, 7SL and 5S RNA. Isoform 2 is required for transcription of the U6 promoter.
Subcellular Location:
Nucleus.
Post-translational modifications:
Phosphorylated upon DNA damage, probably by ATM or ATR.
Similarity:
Belongs to the TFIIB family.
Contains 1 TFIIB-type zinc finger.
SWISS:
Q92994
Gene ID:
2972

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
后DNA仍然保持双链的结构。真核生物RNA聚合酶:真核生物的转录机制要复杂得多,有三种细胞核内的RNA聚合酶:RNA聚合酶I转录rRNA,RNA聚合酶II转录mRNA,RNA聚合酶III转录tRNA和其它小分子RNA。在RNA复制和转录中起作用。 一.模板和酶 1.模板RNA的转录合成需要DNA做模板,DNA双链中只有一股链起模板作用,指导RNA合成的一股DNA链称为模板链(template strand),与之相对的另一股链为编码链(coding strand),不对称转录
RNA Interference (RNAi) With RNase III-Prepared siRNAs
endoribonuclease III to cleave double-stranded RNA (dsRNA) into esiRNA (endoribonuclease-prepared siRNA) that can target multiple sites within an mRNA. EsiRNA mediates effective RNA interference with no apparent nonspecific effects in cultured mammalian cells
