Antisense RNAs have long been known to regulate diverse aspects of plasmid biology. Here we review the FinOP system that modulates F plasmid gene expression through regulation of the F plasmid transcription factor, Trail. FinOP is a two component system composed of an antisense RNA, FinP, which represses TraJ translation, and a protein, Fin, which is required to stabilize FinP and facilitate its interactions with its traJ mRNA target. We review the evidence that Fin acts as an RNA chaperone to bind and destabilize internal stem-loop structures within the individual RNAs that would otherwise block intermolecular RNA duplexing. Recent structural studies have provided mechanistic insights into how FinO may facilitate interactions between FinP and trod mRNA. We also review recent findings that two other proteins, Escherichia coli ProQ and Neisseria meningitidis NMB1681, may represent FinO-like RNA chaperones. (C) 2014 Elsevier Inc. All rights reserved.
