Hfq scaffold sequence
Hfq is an RNA-binding protein that functions primarily as a riboregulator, facilitating the interaction between sRNAs and their target mRNAs. One of the key functions of the Hfq protein is RNA-RNA Interaction, through recognising its cognate Hfq scaffold sequence.
The DNA sequence provided contains a Hfq scaffold sequence to promote the binding of the Hfq protein.
Usage and Biology
One of the key functions of the Hfq protein is to enhance the base-pairing between sRNAs and mRNAs, which can lead to the regulation of translation.
In our design: the Hfq protein binds to sRNAs (an antisense oligonucleotide targeted against T7RNAP mRNA), thereby helping them to recognize and bind to complementary regions on mRNAs. This binding blocks ribosome access to the mRNA's start codon or Shine-Dalgarno sequence, thus inhibiting translation. This helps to knockdown the expression of T7RNAP, thereby regulating the expression of T7RNAP.
Characterization
This part, together with our antisense oligonucleotide (ASO), and a lac promoter acts to regulate the expression of T7RNAP, thereby allowing a stable expression.
