It’s a bit late - but our work on Enhancement Targeting Chimeras (ENTACs) is out now! Check out our work describing how induced proximity of a DUB can stabilise short-lived receptor like CTLA4. @livuni-ismib.bsky.social

Our latest preprint is out! We developed an inducible “RapTag” system that uses ENTAC to chemically recruit USP15 to the unstable protein CTLA4. This induced proximity stabilises and slows down the rapid lysosomal turnover of CTLA4. @livuni-ismib.bsky.social www.biorxiv.org/content/10.1...

Targeted recruitment of USP15 enhances CTLA4 surface levels and restricts its degradation.
Induced protein proximity offers powerful new routes to modulate protein fate. While proteolysis-targeting chimeras (PROTACs) promote degradation through E3 ligase recruitment, the converse principle-...
