Dynamic multivalent interactions of intrinsically disordered proteins.

Protein-protein interactions involving intrinsically disordered proteins (IDPs) usually display dynamic and multivalent features. Recent experimental data revealed myriad functional roles of the dynamic multivalent interaction (DMI) of IDPs. However, characterization of DMI remains a challenge due to its complex and promiscuous nature. Recent studies start showing that understanding the mechanistic role of DMI relies on combined use of various techniques and construction of microscopic models in elucidating the binding thermodynamics and kinetics.
