Abstract
Recent advances in high-throughput sequencing have led to an explosion in the rate of small regulatory RNAs (sRNAs) discovery among bacteria. However, only a handful of them are functionally characterized. Most of the time, little to no targets are known. In Lalaouna et al. (2015), we proposed a new technology to uncover sRNAs targetome, which is based on the MS2-affinity purification (MAPS). We were able to prove its efficiency by applying it on well-characterized sRNAs of Escherichia coli. Thereafter, we adapted the procedure to other kind of RNA (mRNAs and tRNA-derived RNA fragments) and bacteria (pathogenic or Gram-positive strains). Here, we clearly report all improvements and adjustments made to MAPS technology since it was originally reported.
