ProteomicsEstablishment of dimethyl labeling-based quantitative acetylproteomics in Arabidopsis
Protein acetylation, one of many types of post-translational modifications (PTMs), is involved in a variety of biological and cellular processes. In the present study, we applied both CsCl density gradient (CDG) centrifugation-based protein fractionation and a dimethyl-labelling-based 4C quantitativ...

ProteomicsUltra-deep human phosphoproteome reveals different regulatory nature of Tyr and Ser/Thr-based signaling
Regulatory protein phosphorylation controls nearly every normal and pathophysiological signaling system in eukaryotic cells. Despite great advances in mass spectrometry based-proteomics, the total number, localization and site-specific stoichiometry of this post-translational modification (PTM) are ...

ProteomicsDetection and quantitation of small proteins using mass spectrometry
Small proteins or microproteins, despite long being ignored, have important roles in the regulation of larger protein complexes, metabolic pathways and gene expression. However, these proteins remain underrepresented in proteomics studies due to low detection efficiency in traditional mass spectrome...

ProteomicsA workflow towards the reproducible identification and quantitation of protein carbonylation sites in human plasma
Protein carbonylation has been consistently used as a marker of excessive oxidative stress and studied in the context of multiple human oxidative stress related diseases. The variety of carbonyl post-translational modifications (PTMs) and their low abundance on easily accessible diagnostic tissues (...

ProteomicsMultiplexed quantitation of post-translational modified peptides in single cells using triggered MS/MS combined with super heavy tandem mass tags
Recent advances in mass spectrometry now allow unbiased proteome profiling of thousands of proteins from single cells using both label-free and labeling approaches. However, a major limitation of unbiased approaches is missing data, which worsens as the sample size increases. In addition, the reprod...

ProteomicsG6PD K403 acetylation-dependent PTM
To identify acetylation-dependent posttranslational modifications (PTMs) of G6PD, site-specifically acetylated and Flag-tagged G6PD was expressed in HEK293T cells by genetically encoding the incorporation of acetylated lysine in response to an in-frame TAG stop codon. K403-acetylated G6PD (sample) a...
