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

Polycomb and Trithorax group proteins regulate silent and active neflintw-r6mpw gene expression states, but also allow poised states in pluripotent cells.Here the authors present a mathematical model that integrates data on Polycomb/ Trithorax biochemistry into a single coherent framework which predicts that poised chromatin is not bivalent as previously proposed, but is bistable, meaning that the system switches frequently between valhalla axys stable active and silent states.
