Very happy to share our collaborative project on FAM118 proteins - noncanonical sirtuins that form filaments and process NAD in human and other vertebrate cells.

New preprint 🚨 We systematically measured 17 million phospho-specific dose-response curves (133 kinase inhibitors × 5 cell lines) to decrypt the kinases that shape the human phosphoproteome. We show that drug perturbation potency (not effect size) links kinases to substrates while controlling FDR.
Did you ever come across a phosphosite in your proteomics data for which nothing was known? - I bet so!
We have developed a new strategy termed "potency coherence analysis" that leverages the drug potency dimension in decryptM to decode the kinases that shape the human phosphoproteome.

We just took a deep dive into this tour-de-force chemoproteomics paper from @stephanhacker2.bsky.social and colleagues in our journal club today — really interesting findings about selectivity and coverage of 56 different electrophilic warheads, and great experimental and analysis workflows. Bravo!
How can we study target engagement and selectivity of covalent inhibitors? Which electrophilic probes are best suited to study a certain amino acid?
Our study on "Profiling the proteome-wide selectivity of diverse electrophiles" is published in Nature Chemistry.(1/7)
