Characterization of intermolecular base pairing using AMT crosslinking in mammalian cells during oxidative stress
Cellular stress induces global translational repression, leading to exposure of RNA sequences that could engage in intermolecular base pairing. However, characterization of these interactions in stres...

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...

New method drop:
HCR-Proxy, a modular proximity labelling approach to profile local proteome composition around RNA at nanoscale, subcompartmental resolution. Thereby we resolved nested nucleolar layers and uncovered the grammar of spatial protein partitioning.

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...
