New online: Conformational plasticity of a BiP–GRP94 chaperone complex
Conformational plasticity of a BiP–GRP94 chaperone complex
Nature Structural & Molecular Biology, Published online: 14 July 2025; doi:10.1038/s41594-025-01619-0BiP–glucose-regulated protein 94 chaperones are critical to the proper folding of secretory and transmembrane proteins. Brenner et al. provide biochemical and structural insight into a conserved mechanism of chaperone cooperation underlying this quality control process.

Really excited to share the first chapter of my PhD as a preprint titled: Targeted degradation of USP7 in solid cancer cells reveals disparate effects of deubiquitinase inhibition vs. acute protein depletion: www.biorxiv.org/content/10.1.... If that sounds interesting to you, small tweetorial below👇
Targeted degradation of USP7 in solid cancer cells reveals disparate effects of deubiquitinase inhibition vs. acute protein depletion
Proteolysis-targeting chimeras (PROTACs) co-op the ubiquitin system for targeted protein degradation, creating opportunities to interrogate cellular functions of proteins through "chemical knockdown"....

Very excited to share that our work on Parkinson's target USP30 has been published in Nature Structural & Molecular Biology! By combining soluble DUB-domains onto USP30, we for the first time achieved co-crystallization with a small molecule (NK036) without Nanobodies! www.nature.com/articles/s41...
Chimeric deubiquitinase engineering reveals structural basis for specific inhibition of the mitophagy regulator USP30 - Nature Structural & Molecular Biology
Kazi et al. report the crystal structure of the mitochondrial deubiquitinase USP, a clinical stage Parkinson’s disease drug target, in complex with a specific inhibitor. The authors delineate a framew...

I'm super excited to share our study in collaboration with @jnpruneda.bsky.social, published today in @embojournal.org! We show that PARPs are modified with a non-canonical ester-linked mono-ADP-ribosylated ubiquitin species for the first time in cells: www.embopress.org/doi/full/10....

🎉Super excited to share our story on how the substrate receptor FBXO31 functions as a quality control factor by recognizing amides. This has been an amazing collaboration between Bode lab and @jcornlab.bsky.social. Special shutout goes to @matthiasmuhar.bsky.social www.nature.com/articles/s41...
C-terminal amides mark proteins for degradation via SCF–FBXO31 - Nature
SCF–FBXO31 scans proteins for C-terminal amidation and marks them for subsequent proteasomal degradation.

A fantastic story from our lab about finding novel activity in two "inactive" DUBs!
Could't think of a better inaugural post here. Very excited to share that our manuscript on the "Discovery and mechanism of K63-linkage-directed deubiquitinase activity in USP53" was published today at Nature Chemical Biology. Congratulations Kim, Kai, and all authors! www.nature.com/articles/s41...
