Hfq and its constellation of RNA Nature Reviews Microbiology

WebHfq is a bacterial RNA-binding protein that participates in post-transcriptional control of gene expression by facilitating the interactions between small non-coding RNAs and their target mRNAs. WebHfq comprises between 70 and 110 amino acids and forms homohexamers. It is an abundant protein, which is present in up to 60 000 monomers/ E. coli cell in the stationary phase. The major fraction is associated with the ribosomes, whereas a minor Hfq fraction appears to be associated with the nucleoid.
