TRIM28-mediated SUMOylation of G3BP1/2 regulates stress granule dynamics Yuan et al. identify TRIM28 as a key component of stress granules (SGs) using the lcFAX-MS approach established here and define TRIM28-mediated G3BP1/2 SUMOylation as a critical mechanism regulating SG dynamics. TRIM28’s role in regulating SGs, facilitated by lcFAX-MS, provides a promising framework for studying diverse LLPS events.

STT3A is essential for Wnt signaling and represents a target for cancers driven by RNF43 deficiency Loss of RNF43 leads to aberrant Wnt signaling, promoting aggressive cancers for which effective treatments are lacking. He et al. demonstrate that STT3A is critical for the survival of RNF43-deficient tumors, identifying it as a promising therapeutic target validated through both in vitro and in vivo studies.

Therapeutic targeting of WDR5-MLL1 by EMBOW-derived peptides suppresses leukemia progression Targeting the WDR5-MLL1 interaction offers a promising therapeutic strategy for leukemia. Zhang et al. developed Ac7, an EMBOW-derived peptide that binds WDR5 with nanomolar affinity, disrupts the WDR5-MLL1 interaction, and suppresses leukemia cell growth in vivo with relatively low toxicity.

HPV Infections: Friend and Foe

An interesting finding that some types of HPV infection might be preventing cancer (as opposed to the ones that can cause it).

Also features G.K. Chesterton and a brief cameo by RFK Jr.

Computational Care

DiffDock, a new diffusion-based ligand docking program, made s big splash earlier this year. But it’s apparently not all it’s claimed to be:

Thank you @mishtudey.bsky.social and the other organizers for a fantastic symposium. The talks covered broad areas of chemical biology-from targeted protein degradation and molecular glues to sensor development and immuno-oncology. They also represented a nice blend of academic and industry efforts.

Thanks so much for participating and the exciting talk.

Got the chance to put together the "Click of Chemical Biologists" starter pack v1 and v2 over the Thanksgiving Break. Feel free to ping me on who else I might be missing!
