First critical repressive H3K27me3 marks in embryonic stem cells identified using designed protein inhibitor

Abstract

We describe an approach to blocking protein–protein interactions in living cells and use it to probe the earliest stages of epigenetic regulation in stem cell differentiation. We describe a computationally designed protein that tightly binds EED and disrupts PRC2 function in both cancer and stem cells. Expression of the binder at different stem cell stages identifies the first critical repressive H3K27me3 mark in embryonic development.
