ByeTAC: Bypassing E-Ligase-Targeting Chimeras for Direct Proteasome Degradation The development of targeted protein degradation by recruiting a protein of interest to a ubiquitin ligase to facilitate its degradation has become a powerful therapeutic tool. The potential of this approach is limited to proteins that can be readily ubiquitinated and relies on having a ligand with the various E3 ligases. Here, we describe a new methodology for targeted protein degradation that directly recruits a protein of interest to the proteasome for degradation. We generated bifunctional molecules that incorporate a small molecule ligand into a subunit on the 26S proteasome that recruits the protein directly for degradation. ByeTAC degradation requires binding to Rpn-13, a nonessential ubiquitin receptor of the 26S proteasome, and the protein of interest and does not have to rely on the E ligase cascade for ubiquitination. The ByeTAC methodology demonstrates the application of directly recruiting a protein to the proteasome via interactions with Rpn-13 for degradation.

ByeTACs is finally out in J. Med Chem. Congrats team! Can't wait to see how else we can use this degradation technology. @codyloy.bsky.social

A friend drove two hours today for her breast cancer chemotherapy only to learn it was canceled due to NIH cuts. Clinical trial ended midstream. No treatment, no restart, no plan, no information. Her bro-in-law's chemo was also canceled.

Immunoproteasome as a Target for Prodrugs Immunoproteasome (iCP) is a proteasome isoform that is expressed under inflammatory conditions such as cytokine interferon-γ exposure. The iCP has different catalytic subunits other than the standard CP (standard core particle), allowing the production of major histocompatibility complex class I (MHC-I) compatible peptides for eventual T-cell activation. We have previously reported the design of a fluorescent probe that monitors iCP activity in cells called TBZ-1, and we applied TBZ-1’s iCP recognition sequence for prodrug release into iCP-active cells. Here, we demonstrate a proof-of-concept of the iCP as a prodrug release enzyme. The “payload” we utilized was a toxic moiety, doxorubicin, and a degrader for transcription factor, BRD4. Both examples show that iCP activity is required to elicit cell death or degradation of BRD4. This report highlights that the iCP is a viable prodrug target, and its activity can be used to release a variety of cargo in cells expressing the iCP.

Really proud to have this out in J Med Chem! Congrats to Christine and @codyloy.bsky.social

NIH Grants Fueled $95 Billion In FY 2024 Economic Activity, Finds New Report National Institutes of Health grants generated almost $95 billion in economic activity nationwide in FY 2024 according to a new report by United for Medical Research.

New report shows that NIH grants fueled $95 billion in economic activity and 407,782 jobs in 2024.

That's not to mention the countless lives that biomedical research has saved.

Show me a better investment than that.

I got laid off today, with the rest of 18F.

18F was an elite federal software shop. We made gov't websites work better, more efficiently for the American people. We saved taxpayers from getting screwed over by contractors. And were fired for it.

We made this website to tell our story:

Trump's illegal NIH cuts mean cancer researchers would be laid off, sick kids going without treatment, and more. These cuts would be DEVASTATING for lifesaving research.

Some Republicans have said they agree—but they just blocked my amendment to reverse Trump's NIH cuts anyway.
