Set2 methyltransferase catalyzes the lysine 36 methylation of histone H3 (H3K36me) and the enzyme is mutated in many cancers. The authors provide mechanistic insights into how Set2 methylates nucleosomes by determining the 3.8 Å cryo-EM structure of Set2 bound to a H2B ubiquitinated nucleosome core particle.
