Project description:MS2-affinity purification coupled with RNA sequencing (MAPS) reveals S. aureus RsaG sRNA targetome. Affinity purification of in vivo regulatory complexes coupled with high throughput RNA sequencing methodology or MAPS standing for “MS2 affinity purification coupled to RNA".
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 performed MAPS with CyaR 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 GcvB, a sRNA involved in amino acid metabolism.
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 RyhB, a well-characterized E. coli sRNA. Identification of RNAs co-purified with MS2-RyhB in a rne131 ?ryhB strain. RyhB (without MS2) was used as control
