Identification of RNAs that co-purify with the Caulobacter sRNA, GsrN
Ontology highlight
ABSTRACT: Purpose: To identify RNAs that interact with GsrN, a small regulatory RNA from Caulobacter crescentus. Methods: Pseudomonas phage 7 (PP7) viral coat protein fused to maltose binding protein (MBP) was immobilized on amylose resin. PP7 coat protein binds to PP7 RNA hairpins (PP7hp). A strain expressing GsrN tagged with a genetically encoded PP7hp at base 37 (GsrN(37)-PP7hp) was captured on this column, washed, and eluted in biological triplicate (pos_rep). As a negative control, we incubated the PP7 coat protein column with independent duplicate lysates from a Caulobacter strain expressing PP7hp fused to a non-functional 3' isoform of GsrN (mock). We generated RNA-seq libraries for each of three independent GsrN(37)-PP7hp fractions, and the duplicate mock fractions. Results: We quantified levels of RNAs in the GsrN(37)-PP7hp (pos) fractions with fractions from parallel PP7hp-3'GsrN(mock) pull-downs by RNA-seq. From these data, we identified a group of RNAs that were enriched in the GsrN(37)-PP7hp fraction.
