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...

ProteomicsAntibody-Free Profiling of Lysine Dimethylation via Chemoselective OxidationCoupled Reversible Enrichment
Lysine dimethylation (Kme2) is a critical post-translational modification (PTM), while its comprehensive analysis remains challenging due to low stoichiometry and lack of pan-specific antibodies. Here, we developed an antibody-free proteomics strategy combining selective fluorine-mediated oxidation ...

ProteomicsAn automated intact glycopeptide enrichment method for serum site-specific N-glycoproteomic analysis
We developed an automated glycopeptide enrichment method for the analysis of serum site-specific N-glycoproteome. This automated method allowed for processing one sample within 20 min. It showed higher enrichment specificity, more intact glycopeptide identifications, and better quantitative reproduc...

ProteomicsImpaired O-GlcNAcylation rather than N-glycosylation caused by AtAGM deficiency leads to growth variations in Arabidopsis thaliana
To reveal the function of N-acetylglucosamine phosphate mutase (AGM) and UDP-GlcNAc in Arabidopsis growth, WT and a T-DNA insertional mutant Atagm-2 were used for proteomic analysis.

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 ...

ProteomicsHuman serum glycoproteome - Glyco-Decipher
Identification results of peptide-spectrum matches supporting Glyco-Decipher manuscript (Glyco-Decipher: Glycan database-independent peptide matching enables discovery of new glycans and in-depth characterization of site-specific N-glycosylation). Recently, several elegant bioinformatics tools have ...
