One of the main stories of my postdoc is finally out! It builds on an intuition from my early days in omics data analysis: our signaling pathways are simply too small, underrepresenting cellular complexity after stimulation. Something obvious, yet surprisingly hard to quantify.

When I first learned about omics at university, I confidently stopped caring about single proteins. Fast-forward 4 years of a system’s biology PhD, I now have the most amazing favorite single protein which I can’t stop thinking about. Here is the story of how that happened 👀

Never thought I'd co-first author a paper that appears on the screens on campus, that makes me very happy😃

A CK2-FBXW11 kinase-E3 ubiquitin ligase cascade is a metabolic sensor regulating Tryptophan 2,3-dioxygenase stability Small molecules toggling the ubiquitin-proteasome system (UPS) are powerful regulators of protein degradation. Yet, mechanistic knowledge of how endogenous ligands gate UPS decisions remains rudimentary. Here, we define control of UPS access to Tryptophan-2,3-dioxygenase (TDO2), which converts the essential amino acid tryptophan (Trp) to N-formylkynurenine. When Trp concentrations are limiting, TDO2 is degraded to avert tryptophanemia. Using CRISPRi screening and biochemistry, we identify a CK2-FBXW11 kinase-E3 ligase cascade that generates and recognizes tandem TDO2 phosphodegrons when not protected by Trp. Trp binding to an exosite safeguards TDO2 from phosphorylation-dependent ubiquitylation. Effects of Trp analogs on CK2-FBXW11-dependent ubiquitylation indicated that the indole, amino, and carboxylate groups are necessary for substrate shielding. Cryo-EM reveals how these moieties order a region proximal to the phosphodegrons; without Trp, this segment is flexible, enabling phosphorylation-coupled ubiquitylation. Overall, our data uncovered an endogenous small molecule allosterically stabilizing its own metabolizing enzyme through protection from a phosphorylation-ubiquitylation cascade. ### Competing Interest Statement B.A.S. is a member of the scientific advisory boards of Proxygen and Lyterian.

CORNETO: machine learning to decode complex omics data New tool combines biological knowledge with machine learning to help researchers extract meaningful insights from complex omics data.

How can we find out what’s really going on inside cells when we’re generating so much complex data?

CORNETO is an open-source tool that uses machine learning to turn tangled omics datasets into clear maps of how genes, proteins, and signalling pathways interact.

Bacteria can influence how sugars modify proteins in the brain – shown for the first time by EMBL researchers.

In their study, the scientists describe a new method to study glycosylation systematically & quantitatively, leading to new biological insights. 🧪🧠📈
