TranscriptomicsMediator Complex Regulates Alternative mRNA Processing via the Med23 Subunit
Mediator complex is an integrative hub for transcriptional regulation. Here we show that Mediator regulates alternative mRNA processing via its Med23 subunit. Combining tandem affinity purification and mass spectrometry, we identified a number of mRNA processing factors that bind to a soluble recomb...

ProteomicsDependency of NELF-E-KAT2B epigenetic axis in breast cancer carcinogenesis
Cancer cells undergo transcriptional reprogramming to drive tumor progression and metastasis. Here, we identified the transcriptional complex, NELF (Negative elongation factor), as an important regulator of this process. Using cancer cell lines and patient-derived tumor organoids, we demonstrated th...

ProteomicsIdentification of TRADD phosphorylation sites
We re-introduced Flag-mTRADD into Tradd-/- MEFs, and identified the phosphorylation sites of TRADD which were induced by TNF and inhibited by TAK1 inhibitor 5Z7 using mass spectrometry. We found that TAK1 could mediate the phosphorylation of multiple sites in TRADD upon TNF stimulation. We next perf...
