Happy to see our work on defining a dependency map of short linear motifs out. We use base editing screens to install more than 80000 mutations into SLiMs in more than 4000 proteins to determine their contribution to cell fitness. www.nature.com/articles/s41...

Systematic Discovery of Motif-based Interactions of the Auxiliary Domains of USP Family Deubiquitinases The ubiquitin-specific proteases (USPs) family is the largest family of human deubiquitinating enzymes (DUBs). While most USPs are agnostic to polyubiquitin linkage-type, their substrate specificity i...

Finally out! Thrilled to share our collaboration with @kulathu.bsky.social, @orafurman.bsky.social, and N Davey. We screened auxiliary domains of USP family #deubiquitinases, revealing short linear motifs (SLiMs), contributing to specificity in complex assembly.

Not sure if Trump getting the Nobel Prize medal from Machado is more embarrassing for Trump, Machado, the Norwegian Nobel Committee, or the USA as a country.

Applications for ERC Synergy Grants 2026: Facts and figures The ERC Synergy Grants 2026 call closed for applications on 5 November 2025. These are the preliminary data on the submitted proposals:

957 proposals were submitted in the latest round of ERC Synergy applications. They expect to fund 50 which means around 5% success rate. This is really not sustainable and a lot of people are likely avoiding doing this knowing how poor the chances are.
