Polycomb repressive complex 2 (PRC2) was originally discovered in fruit flies as a transcriptional repressor. Historically, fly and human Polycomb proteins were considered textbook exemplars of transcriptional repressors, or proteins that silence the process by which DNA gives rise to new proteins. Now, work by a team of researchers at the Stowers Institute for Medical Research challenges that dogma.
