Recognition-dependent activation of the RRS1-R/RPS4 immune receptor complex

This study investigates the oligomerization and activation mechanism of the RPS4-RRS1 immune receptor complex in Arabidopsis, showing that effector recognition triggers conformational changes that enable NADase activity.

Water oxidation-driven histidine dioxidation enables probe-free proximity labeling

This paper introduces PF-Map, a probe-free proximity labeling method using water oxidation to generate radicals for spatial protein mapping, revealing a hidden vesicle trafficking subproteome.

Deciphering the oxidative modifications via disulfide mapping

This study uses non-reducing proteomics to reveal disulfide crosslinks in proteins under oxidative stress, showing their role in redox regulation.

The antibody repertoire of colorectal cancer

The paper introduces AbScan, a proteogenomic method to identify antibody peptides from RNA-seq data, and applies it to colorectal cancer samples to find correlations between antibody peptides and survival.
