Understanding the structural basis of actin cytoskeleton remodelling requires stabilization of actin monomers, oligomers and filaments in complex with partner proteins using various biochemical strategies. Here we report a dramatic destabilisation of the dynamic interaction with a model β-thymosin/WH2 domain induced by mutations in actin. This result underlines that mutant actins should be used with prudence to characterise interactions with intrinsically disordered partners as destabilisation of dynamic interactions, although identifiable by NMR, may be invisible to other structural techniques. It also highlights how both β -thymosin/WH2 domains and actin tune local structure and dynamics in regulatory processes involving intrinsically disordered domains.
