Name:RNA-binding protein Hfq
Synonyms:Not Available
Gene Name:hfq
Enzyme Class:Not Available
Biological Properties
General Function:regulation of transcription, DNA-templated
Specific Function:RNA chaperone that binds small regulatory RNA (sRNAs) and mRNAs to facilitate mRNA translational regulation in response to envelope stress, environmental stress and changes in metabolite concentrations. Involved in the regulation of stress responses mediated by the sigma factors RpoS, sigma-E and sigma-32 (PubMed:17158661). Binds with high specificity to tRNAs (PubMed:18230766). Binds sRNA antitoxin RalA (PubMed:24748661). In vitro, stimulates synthesis of long tails by poly(A) polymerase I (PubMed:10677490). Required for RNA phage Qbeta replication (PubMed:805130). Seems to play a role in persister cell formation; upon overexpression decreases persister cell formation while deletion increases persister formation (PubMed:19909729).
