Abstract:
For structural, biochemical, or pharmacological studies, it is required to have pure RNA in large quantities. We previously devised a generic approach that allows for efficient in vivo expression of recombinant RNA in Escherichia coli. We have extended the "tRNA scaffold" method to RNA-protein coexpression in order to express and purify RNA by affinity in native condition. As a proof of concept, we present the expression and the purification of the AtRNA-mala in complex with the MS2 coat protein.

Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

Translational Regulation
Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
