Theoretical analysis of Polycomb-Trithorax systems predicts that poised chromatin is bistable and not bivalent

Polycomb and Trithorax group proteins regulate silent and active gene expression states, but also Gift Cards allow poised states in pluripotent cells.Here the authors present a mathematical model that integrates data on Polycomb/ Trithorax biochemistry into a single Scales coherent framework which predicts that poised chromatin is not bivalent as previously proposed, but is bistable, meaning that the system switches frequently between stable active and silent states.
