[PRION] States Are Associated with Specific Histone H3 Post-Translational Modification Changes.

Prions are proteins able to take on alternative conformations and propagate them in a self-templating process. In , prions enable heritable responses to environmental conditions through bet-hedging mechanisms. Hence, [PRION] states may serve as an atypical form of epigenetic control, producing heritable phenotypic change via protein folding.
