A Mass Spectrometry-Based Proteomics Approach for Global and High-Confidence Protein R-Methylation Analysis
Chapters

- 00:44Lysate Digestion
- 02:08Off‐Line HpH‐RP Chromatographic Fractionation of Peptides
- 02:53R‐Methylated Peptide Immuno‐Affinity Enrichment
- 06:47Results: R‐Methylation Analysis by Mass Spectrometry
- 08:39Conclusion
Protein Arginine (R)-methylation is a wide-spread post-translational modification regulating multiple biological pathways. Mass spectrometry is the best technology to globally profile the R-methyl-proteome, when coupled to biochemical approaches for modified peptide enrichment. The workflow designed for the high confidence identification of global R-methylation in human cells is described here.
