Project description:Recently, we developed an in vivo technology to draw the interacting map of a specific small regulatory RNA (sRNA). We called it MAPS for MS2-affinity purification coupled with RNA sequencing. Using this technology, we already revealed the targetome of RyhB, RybB and DsrA, three well-characterized sRNAs in Escherichia coli. In this study, we perform MAPS with RprA sRNA.

Using this technology, we already revealed the targetome of RyhB, RybB and DsrA, three well-characterized sRNAs in Escherichia coli. In this study, we perform MAPS with GcvB, a sRNA involved in amino acid metabolism.
Project description:The virulon of Staphyloccocus aureus is controlled by intricate connections between transcriptional and post-transcriptional regulators including proteins and small non coding RNAs (sRNAs). Most of the sRNAs regulate gene expression through base-pairings with mRNAs. Here, we have applied and adapted the MS2-affinity purification approach coupled to RNA sequencing (MAPS) to determine the targetome of RsaI sRNA of S. aureus.

Project description:Despite the overwhelming information about sRNAs, one of the biggest challenges in the sRNA field is characterizing sRNA targetomes. Thus, we develop a novel method to identify RNAs that interact with a specific sRNA, regardless of the type of regulation (positive or negative) or targets (mRNA, tRNA, sRNA). This method is called MAPS: MS2 affinity purification coupled with RNA sequencing. As proof of principle, we identified RNAs bound to RybB, a well-characterized E. coli sRNA. Identification of RNAs co-purified with MS2-RybB in a rne131 ΔrybB strain. RybB (without MS2) was used as control
