We expand the range of zinc finger transcription factors that can be targeted by degraders via CRBN. Once thought undruggable, our work shows how functional genomics uncovers new targets missed by proteomics and reveals rules for the structure–activity relationship of compounds.

[Mikołaj Słabicki @biomiko]

We mapped the zinc‑finger (ZF) “degrome.” High‑throughput ZF reporters + glutarimide analogs → new CRBN‑recruited degrons and design rules for degraders.

@FranziskaWacht1 @DFBC_PedCare @BostonChildrens @DFCI_ChemBio @DFCI_CCBM @fischerlab1 Congrats Franzi!

[Shourya S Roy Burman @ssroyburman]

Amazing discovery on how some transcription factors self-polymerize to function. Opens the door for yet another ligandable way to target the function of these "undruggable" proteins. Congrats on making the cover Paul Park and @jihojasonpark!

[Jiho Park @jihojasonpark]

Excited to share our story on polymerization in ZBTB transcription factors, which was published in the July 11 issue of @MolecularCell! https://t.co/qlzxfF0PR4 1/n

[The Roberts Lab @TheRobertsLab1]

Just in time for #HumpDay: Our study Targeting DCAF5 suppresses #SMARCB1-mutant #cancer via stabilizing SWI/SNF is online now in @Nature. Congratulations 🎉 to co-first authors Sandi-Radko-Juettner and @HongYue88665668 and all co-authors on this story! 1/

Having enjoyed the paper from @davidrliu, @fischerlab1, and @ChoudharyLab in @ScienceMagazine this week, we have now posted our own, complementary, taken on a bump-and-hole approach to develop an orthogonal bumped IMiD-degron pair: https://t.co/drgAHGo5zx.

[Shourya S Roy Burman @ssroyburman]

@moritzhunkeler Yeah, several months spent purifying different constructs in different expression systems to isolate the ZnF. Turns out the first bacterial tagged construct we had was good enough. Funny how these things work out.

[David R. Liu @davidrliu]

Thanks for your comments, Jay. To answer your question:
1) dTag uses FKBP12-F36V, which is 108 amino acids (324 bp). Unfortunately this size is too large to be directly and scarlessly installed using prime editing; we tried as part of our TwinPE studies (https://t.co/E7Wf39V1JC) but could only precisely install ~1/3 of the FKBP12 gene efficiently.
2) dTag small molecules degrade off-target ZF proteins, as shown in the attached figure from https://t.co/yK9t15Kax8
3) The dTag system requires heterobifunctional molecules consisting of AP1867—linker—IMiD, and thus are subject to hook effects as you showed in your beautiful NCB paper.

I appreciate that #2 and #3 might be addressed with dose-finding though it would be preferable to avoid the issues all together. You could install dTag or other larger degron tags with HDR though generally with lower efficiency, higher byproducts, and the consequences of making chromosomal breaks.

[Broad Institute @broadinstitute]

A new PACE-based system generates protein degradation tags that interact with an otherwise-inert small molecule to trigger the rapid breakdown of a cell’s native proteins, with molecular glue systems that can become useful new research tools. https://t.co/QUhXSYr1RG

[Shourya S Roy Burman @ssroyburman]

And to @CancerResearch for funding this moonshot project of making potent degrons that can act as post-infusion switches in the next generation of engineered cell therapies.

[Shourya S Roy Burman @ssroyburman]

We engineered a new tool to interrogate biological pathways and validate cancer dependencies! This new degron can be fused to your protein of interest at its genomic locus to degrade it within an hour using a clean compound. https://t.co/jTcTpOE7Jg

[David R. Liu @davidrliu]

Today in @Science_Magazine we report the laboratory evolution of compact degrons that enable targeted protein degradation triggered by an otherwise-inert small molecule, a multidisciplinary study that integrates organic chemistry, molecular glues, protein evolution, genome editing, and structural biology.

Big thanks to @moritzhunkeler, @SDixonClarke, @HC2EM, @SBGrid for the structure. And @kdonovan1008, @eric_fischer, and @fischerlab1 for proteomics, biochemistry, and everything else. Glad to be part of this wonderful collaboration with @davidrliu lab and @ChoudharyLab.
