RsmX
RsmX is a small non-coding regulatory RNA (sRNA) found in several Pseudomonas species, most prominently in Pseudomonas aeruginosa. It forms part of the Rsm (or CsrA-like) regulatory network that controls post-transcriptional gene expression. As an sRNA, RsmX does not encode a protein; instead, it modulates gene expression by interacting with RNA-binding proteins of the RsmA family.
The primary mechanism of action involves sequestering RsmA-type proteins (and related regulators such as RsmE) away
Expression of RsmX is governed by the GacS/GacA two-component regulatory system, which coordinates the entire Gac
Beyond Pseudomonas, homologous RsmX-like RNAs have been identified in related bacteria, suggesting a conserved role in
