ProteomicsRevealing Stress Granule Compositional Heterogeneity through Antibody-Guided Proximity Labeling
Stress granules (SGs), transient nonmembranous cytoplasmic condensates that formed in response to cellular stresses, require precise characterization to unravel their cell-type and stressspecific protein compositions. This study introduced a G3BP1 antibody-guided proximity labeling (Ab-PL) method to...

ProteomicsOne-Step Chemoenzymatic Labeling and Oxime-Reversible Enrichment for O-GlcNAc Profiling in Oxidative Stress
Chemoenzymatic labeling has greatly advanced O-GlcNAc proteomics, yet existing strategies using azide-modified donors (e.g., UDP-GalNAz) require multi-step click-based workflows that introduce substantial sample loss and limit sensitivity toward low-abundance targets. While recent one-step labeling ...
