They include a T7 promoter comprising the T7 gene 10 translation enhancer , an efficient prokaryotic Shine-Dalgarno sequence with an optimum distance to the start codon, a multiple cloning site, and a T7 terminator which prevents 3'-terminal exonucleolytic degradation of the mRNA. These vectors are very convenient since multiple cloning sites were designed to allow gene fusions with several tags either at the N- or C-terminal of target proteins by conserving the same restriction strategy and ...

RNA polymerase I is located in the nucleolus, a specialized nuclear substructure in which ribosomal RNA (rRNA) is transcribed, processed, and assembled into ribosomes (Table 1). The rRNA molecules are considered structural RNAs because they have a cellular role but are not translated into protein.
However, in most cases, RNA probes are obtained by in vitro transcription from plasmids containing specific promoter elements and mRNA-specific cDNA. Two-step PCR amplification ensured high fidelity in the synthesis of special DNA sequences and the T7 RNA polymerase promoter.
The C-terminal domain of the α subunit (αCTD) of Escherichia coli RNA polymerase is often involved in transcriptional regulation. The αCTD typically stimulates transcription via interactions with promoter UP element DNA and transcriptional activators. DNase I footprinting and gel mobility shift assays were used to look for potential interaction of the αCTD with the phage Mu middle promoter ...
