10 unusual facts about Hfq protein


AfaR small RNA

It is an Hfq-dependent RNA which downregulates AfaD-VIII invasin translation by binding to and initiating cleavage of its mRNA.

Escherichia coli sRNA

From this set of candidate genes, microarray analysis and northern blotting confirmed the existence of 17 previously undescribed sRNAs, many of which bind to the chaperone protein Hfq and regulate the translation of RpoS (Sigma 38).

GadY

It has been shown that all three forms of GadY bind to the Hfq protein.

GcvB RNA

This binding is dependent on binding to a protein called Hfq protein.

Listeria Hfq binding LhrA

Listeria Hfq binding LhrA is a ncRNA that was identified by screening for RNA molecules which co-immunoprecipitated with the RNA chaperone Hfq.

Listeria Hfq binding LhrC

Listeria Hfq binding LhrC this ncRNA was identified by screening for RNA molecules which co-immunoprecipitated with the RNA chaperone Hfq.

OmrA-B RNA

They negatively regulate the expression of several genes encoding outer membrane proteins, including cirA, CsgD, fecA, fepA and ompT by binding in the vicinity of the Shine-Dalgarno sequence, suggesting the control of these targets is dependent on Hfq protein and RNase E.

Qrr RNA

It is believed that these RNAs, guided by a protein, Hfq, can mediate the destabilisation of the quorum-sensing master regulators LuxR/HapR/VanT mRNAs.

RydC RNA

RydC is known to bind the Hfq protein, which causes a conformational change in the RNA molecule.

Vibrio cholerae ToxT activated RNAs

Regulation of PtsG by TarA may be dependent upon the Hfq protein, an RNA chaperone.
