Histone methylation is associated with both transcription activation and repression. However, the functions of different states of methylation remain largely elusive. Here, using methyl-lysine analog technology, we demonstrate that the histone deacetylase complex, Rpd3S, can distinguish the nucleosomes methylated to different extents and that K36me2 is sufficient to target Rpd3S in vitro. Through a genome-wide survey, we identified a few mutants in which the level of K36me3 is significantly reduced, whereas the level of K36me2 is sustained. Transcription analysis and genome-wide histone modification studies on these mutants suggested that K36me2 is sufficient to target Rpd3S in vivo, thereby maintaining a functional Set2-Rpd3S pathway.
