Research
Storz's research interests include the characterization of small
non-coding RNA and small proteins of 50
amino acids or less. An early focus of her research was the study of redox-sensitive
transcription factors and the bacterial and yeast responses to
oxidative stress. She discovered that the activity of the
Escherichia coli transcription factor OxyR, now a paradigm for other redox-sensitive proteins, is regulated by reversible
disulfide bond formation and elucidated how disulfide bond formation controls the nuclear localization of the
Saccharomyces cerevisiae transcription factor Yap1. As a result of her group's serendipitous detection of the
OxyS RNA, one of the first small
regulatory RNAs to be discovered, attention shifted to the genome-wide identification and characterization of small
regulatory RNAs in the
model organism Escherichia coli. Work on
small RNAs in Dr. Storz's lab revealed that the RNA chaperone
Hfq stimulates the pairing of the majority of the
small RNAs with
mRNA targets and that
small RNAs are integral to most regulatory circuits in bacteria. While identifying these
small RNAs, her lab discovered that some of these small RNAs encode small proteins that had previously been overlooked because they are not detected in many traditional biochemical assays and the corresponding genes are poorly annotated. Her research group demonstrated that one such small protein, AcrZ, binds to the multidrug efflux pump protein
AcrB to affect its ability to export certain classes of antibiotics. The Storz lab currently seeks to identify and to characterize the function of other small proteins from
Escherichia coli. ==Awards and honors==
