Today in @NatureGenet, we report a saturation genome editing study that systematically dissects the degron of β-Catenin: one of the most frequently mutated regions of the cancer genome. Collab with @kiddevonline and @DeryaDOzdemir, among many others

This reveals a synthesis‑dependent ceiling on degradation, with implications for:
• interpreting preclinical degrader data
• resistance mechanisms
• genotype‑guided therapy design
🔬 New lab preprint: How does the mode of oncogene activation shape PROTAC efficacy?
Led by Evelina Gudauskaite, we ask whether stabilising mutations vs transcriptional upregulation have distinct consequences for targeted protein degradation.
https://t.co/vH8Dcud4yg.
Using a controlled cellular system (dTAG + TetOn3G), we found:
✅ Stabilising mutations don’t limit PROTAC action—degradation resets protein levels to the same baseline.
❌ Increased transcription raises target protein levels both pre‑ and post‑treatment.
Beautiful new UK Wnt paper out now in @NatureGenet by Peter Hohenstein @AndrewWoodLab and Derya Ozdemir @UniLeidenNews@EdinburghUni@kocuniversity characterising the molecular/functional impact of numerous CTNNB1 mutational variants in human cancer.

Major new direction in the @stark_lab: hacking human cell biology with pathogen effectors (eORFs) - amazing collaboration with @mike_tilapia lab. Huge congrats to first authors Tomas & He & all co-authors! Check out the pre-print on @biorxivpreprint https://t.co/deg699JIWi
1/ Happy to share important work done with my co-author Andrew Khalil in the labs of Rudolf Jaenisch @WhiteheadInst@MITBiology@MIT and Dave Mooney @Harvard@wyssinstitute trying to assess and fix the major problem of transgene silencing in human ESC/iPSC based work
The big one is finally out!! In this paper, we set out to provide insight into the fundamental question;
How do the individual cells from complex tissues regulate their proteomes?
Brief summary of our findings 👇

Nice write up on the @MRCMouseNetwork website, highlighting the awesome work of first author Gillian Taylor, is available here: https://t.co/NWKh4XWDZV
Our manuscript characterising tissue-specific consequences of tagged protein fusions in CRISPR-engineered mice is now online @PLOSGenetics. https://t.co/walorzG7qO. Thanks again to all coauthors, reviewers and editors for a smooth publication process.
Happy to share our latest work and first manuscript from the Degron Tagging Cluster @MRCMouseNetwork. If you work with protein tags, particularly in tissue biology models, this should be of interest.

We characterise two underlying mechanisms with opposing effects on protein stability and explain their tissue-specificity, providing a rational basis for improved experimental design. Congrats to 1st author Gillian Taylor and all who contributed. Feedback welcome!

By surveying a series of CRISPR-engineered mice, we found that tags often change protein expression in some tissues but have little effect, or even opposite effects, in others. Why?
