Elucidating binding mechanisms and dynamics of intrinsically disordered protein complexes using NMR spectroscopy

Résumé

Advances in characterizing complexes of intrinsically disordered proteins (IDPs) have led to the discovery of a remarkably diverse interaction landscape that includes folding-upon-binding, highly dynamic complexes, multivalent interactions as well as regulatory switches controlled by post-translational modifications. Nuclear magnetic resonance (NMR) spectroscopy has in recent years made significant contributions to this field by describing the binding mechanisms and mapping conformational dynamics on multiple time scales. Importantly, this progress has been associated with specific methodological developments in NMR, for example in exchange techniques, allowing challenging biological systems to be studied at atomic resolution. In general, the level of dynamics observed in IDP complexes does not correlate with binding affinities, demonstrating the intricate relationship between conformational dynamics and IDP regulatory function.
