How much protein diversity are we missing? Our Cell Reports study combines long-read transcriptomics with IsoFrac proteomics. Most detectable alternative transcripts are translated. And shorter protein variants emerge as a major source of proteome complexity. doi.org/10.1016/j.ce...

New preprint from our lab: proteome-wide analysis of gene expression noise in mammalian cells using single-cell proteomics. We find that variability of abundant proteins is largely extrinsic and reflects coordinated cellular states. tinyurl.com/2jyxeym7

Spike-in enhanced phosphoproteomics uncovers synergistic signaling responses to MEK inhibition in colon cancer cells
Nature Communications - Kinase inhibitors are key in cancer therapy, but resistance limits their efficacy. Here, the authors develop SPIED-DIA, a phosphoproteomics method enhancing detection of key...

Our work on deriving protein-protein (functional) associations across different human tissues from proteomics data is now published. There is quite a lot in this paper, so I will just touch on a few highlights: www.nature.com/articles/s41...

Alternative splicing (AS) is common, but its impact on the proteome remains debated, especially in primary cells. What determines which AS isoforms result in abundant proteins ? We find that proteoform-specific ... 🧵 www.biorxiv.org/content/10.1...

What happens to all those alternative transcripts? 👉 Many are translated. 👉 Proteolytic processing adds even more diversity. Integrated mRNA & protein isoform landscape now out on bioRxiv! 🔗 doi.org/10.1101/2025... #proteomics #transcriptomics #systemsbiology
