Professor, Founder and Director of the Centre for Targeted Protein Degradation at the University of Dundee. We develop molecules that induce protein interactions and degradation

Delighted to see this, many congratulations and fully deserved! The Boehringer foundation and your colleagues are lucky to have your vision leading this initiative. I am excited as our collaboration will thrive in your new home, and by opportunities for AITHYRA and CeTPD to work together in future

Something that qualifies as big news from my side: I am very happy and excited to announce that I have been appointed as Life Science Director at AITHYRA, a new Research Institute for Biomedical Artificial Intelligence. Find out more in the link and 🧵 below lnkd.in/d_HaGuSE

Collaboration with @supertifurgalab.bsky.social out in @cp-cellchembiol.bsky.social we identify a role of ABCC1 transporter in PROTAC efflux. It turns out, getting in is surprisingly not often the problem; it’s keeping it once inside the cell! Maybe some wider lessons. Designing it out could be key

Kicking off the new year: A collaboration between @giuliosupertifurga.bsky.social and @alessiociulli.bsky.social using a transporter-focused genetic screens revealed that the efflux pump ABCC1/MRP1 restricts PROTAC sensitivity in cancer cells. Out now in @CellChemBiol www.cell.com/cell-chemica...

Dual-ligase PROTACs: a novel approach for enhancing TPD. By recruiting two distinct E3 ligases within a single molecule, we amplify degradation efficacy & potentially mitigate resistance occurrence. Great collabo with the Ciulli lab & friends at Promega. pubs.acs.org/doi/10.1021/...

Leveraging Dual-Ligase Recruitment to Enhance Protein Degradation via a Heterotrivalent Proteolysis Targeting Chimera

Proteolysis targeting chimera (PROTAC) degraders are typically bifunctional with one E3 ligase ligand connected to one target protein ligand via a linker. While augmented valency has been shown with trivalent PROTACs targeting two binding sites within a given target protein, or used to recruit two different targets, the possibility of recruiting two different E3 ligases within the same compound has not been demonstrated. Here we present dual-ligase recruitment as a strategy to enhance targeted protein degradation. We designed heterotrivalent PROTACs composed of CRBN, VHL and BET targeting ligands, separately tethered via a branched trifunctional linker. Structure–activity relationships of 12 analogues qualifies AB3067 as the most potent and fastest degrader of BET proteins, with minimal E3 ligase cross-degradation. Comparative kinetic analyses in wild-type and ligase single and double knockout cell lines revealed that protein ubiquitination and degradation induced by AB3067 was contributed to by both CRBN and VHL in an additive fashion. We further expand the scope of the dual-ligase approach by developing a heterotrivalent CRBN/VHL-based BromoTag degrader and a tetravalent PROTAC comprising of two BET ligand moieties. In summary, we provide proof-of-concept for dual-E3 ligase recruitment as a strategy to boost degradation fitness by recruiting two E3 ligases with a single degrader molecule. This approach could potentially delay the outset of resistance mechanisms involving loss of E3 ligase functionality.
