Postdocs Nirbhik Acharya and @jessniblo.bsky.social worked awesomely together to show how disordered regions regulate folded domain interactions that affect UBQLN structure, dynamics, and binding. Illustrating the power of experimental (NMR, SAXS) and computational collabs on full-length proteins!!!

A great collaboration with our next door neighbors @castanedalab.bsky.social! We show how disordered regions 🍝 have hotspots that drive intramolecular interactions, regulating multi-domain protein topology and function. See more in Jess' post 👇

Intramolecular interactions between folded and disordered regions shape ubiquilin structure and function Multidomain proteins consist of folded domains connected by intrinsically disordered regions. The flexibility afforded by the disordered regions coupled to the structure and surface chemistry of folded regions allows for unique structural and functional features in these proteins. Yet how intramolecular interactions between disordered regions and folded domains affect multidomain protein structure and function remain poorly understood. Here we use a range of biophysical and computational approaches to measure the intramolecular interactions between the folded domains and disordered regions of ubiquilins (UBQLNs) - essential components of protein quality control that shuttle poly-ubiquitinated client proteins to proteasomal degradation or autophagy. Starting with the yeast UBQLN homolog Dsk2, we find that interactions between two folded domains located at the opposite ends of UBQLN bring about a closed conformation. The prevalence of this closed conformation, however, is modulated by intramolecular interactions involving the disordered regions and folded STI1 domain at the center of the protein. Simulations and analysis of UBQLN homologs across multiple eukaryotic lineages reveals that these disordered:folded domain interactions exist in some UBQLN homologs but are absent in others, indicating possible fundamental differences in function among proteins with the same multidomain architecture. ### Competing Interest Statement The authors have declared no competing interest.

Ever wonder how IDRs and folded domains work together to control function? Using ubiquilins, multidomain proteins involved in protein degradation, we show in our new preprint that IDRs aren’t just linkers, but regulate ensemble and function. Read it here: doi.org/10.64898/202...

I am thrilled to announce publication of our new paper! We show transcription factor evolution in fungi is driven evolutionary turnover at two length scales. 1) Turnover of entire activation domains and 2) turnover of key residues within an activation domain. journals.plos.org/plosgenetics...
