Engineering Segmentally Labeled Intrinsically Disordered Proteins, Erin Rosenkranz

WWU Graduate School Collection

It has long been accepted that a protein’s fold informs its function, but for the vital proteins that don’t adopt one specified fold, this is uninformative. Intrinsically disordered proteins have non-folded regions (IDRs) in their native functional state, which make up 30% of eukaryotic proteins, perform vital cellular processes and contribute to a multitude of disease states. Yet, IDR’s function, interactions and dynamics remain unknown due to their unstable, dynamic, lengthy and solvent-exposed nature. This, along with their tendency for insolubility and aggregation provide formidable challenges to not only their analysis, but their purification, requiring lengthy optimizations. NMR is valuable …
