New origin story for key regulatory gene: PRC2 repressed jumping genes in ancestors of eukaryotes

The key protein complex PRC2 was discovered decades ago to silence genes, but new findings by Frederic Berger and his group at the Gregor Mendel Institute show that PRC2 represses transposons in a range of eukaryotes and only gradually evolved to silence genes. The study was published on September 21 in the journal Current Biology.
