Our first graduate student, Siran Tian, is graduating. For her thesis, she characterized intermolecular base pairing (PMCID: PMC12398620) and the role of the conserved DEAD-box RNA helicase Vasa in regulating protein–protein and protein–RNA interactions (PMCID: PMC12724462) in fly germ granules.

Our new paper is out in PNAS! We show that competition for binding to the Hfq matchmaker disfavors mismatched sRNA-mRNA combinations while allowing matched sRNA-mRNAs to form stable pairs. Kudos to Jorjethe Roca and Yi-Lan Chen for their fantastic work on this problem! doi.org/10.1073/pnas...

Competition for Hfq drives kinetic selection of mRNA targets by Escherichia coli small noncoding RNAs | PNAS

Small noncoding RNAs (sRNAs) regulate gene expression in Escherichia coli bacteria in response to diverse stimuli in the environment and the host. ...

Excited to share our lab's preprint! We found that flexible RNAs have much broadened ion atmospheres than structured RNAs. This leads us to speculate the implications on molecular recognition and phase behavior. Please check full text for other interesting details www.biorxiv.org/content/10.1...

RNA structural complexity dictates its ion atmosphere

Electrostatic interactions mediated by the surrounding ions govern virtually every facet of RNA behavior. Most studies have focused on rigid, well-folded motifs, leaving the structurally heteregeneous...
