EZH2 , a SET domain protein, trimethylates histone H3 at lysine 27 (H3K27) and lysine 9 (H3K9) (Kuzmichev et al. 2002, Cao et al. 2002, Kuzmichev et al. 2004, Martin et al. 2006, McCabe et al. 2012, Swalm et al. 2013). EZH2 has greater activity with lysine residues that have fewer methyl groups (unmethylated:monomethylated:dimethylated=9:6:1, McCabe et al. 2012). EZH1 rather than EZH2 is present in some PRC2 complexes and can also catalyze the trimethylation of H3K27 (inferred from mouse in Shen et al. 2008), however EZH1 is also able to repress transcription without methylating histone H3 (Margueron et al. 2008).
