ProteomicsMass spectrometry data for PAL-catalyzed peptide cyclization and affibody–peptide ligation
This dataset contains mass spectrometry measurements acquired to verify peptide products generated by a peptide asparaginyl ligase (PAL)-catalyzed reaction, including (i) peptide substrate cyclization and hydrolysis side product formation, and (ii) protein–peptide ligation. For cyclization, the line...

ProteomicsProteomic landscape of serum exosomes to identify potential therapeutic targets.
Using a tandem mass tag (TMT)-based quantitative proteomics approach, we characterized the proteomes of individual patient-derived serum exosomes, identified exosomal protein signatures specific to TNBC patients, and filtered out differentially expressed proteins.

ProteomicsChromatin bound O-GlcNAc proteins related to stress response and transcriptional regulation.
O-GlcNAcylation performs a critical role in regulating stress response program and cellular homeostasis. However, systematic studies of O-GlcNAc regulated genotoxic stress-responsive transcriptional reprograming have been limited. The GalNAz metabolic labeled global chromatin-associated proteins wer...
