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.

When RNA Degradation ๐ค meets ๐ค Protein Degradation! tinyurl.com/E3TDMD In a collaboration of @bartellab.bsky.social and Schulman lab, we show that, in target-directed microRNA degradation (TDMD), 2-RNA-factors recruit an E3 ligase and induce the degradation of not only a protein but also RNA (1/5).
