Allostery is central to regulation of protein function, but our mechanistic understanding remains incomplete. A deeper understanding of how redistributions of conformational states drive allostery in proteins could allow us to better grasp natural regulatory principles in cells and open new doors to therapeutic development. Conformationally dynamic human Protein Tyrosine Phosphatases (PTPs) exemplify the challenges and opportunities associated with allostery. The archetypal PTP, PTP1B, has been highly validated as a therapeutic target but no allosteric inhibitors have been approved for clinical use. This is largely because our understanding of the mechanisms underlying allostery in PTP1B remains limited, despite the discovery …
