Table 1. EZH2 methylation sites on its histone and non-histone protein substrates.
Shown on each row are the reported substrate, starting aa position, the aa sequence flanking the methylation sites (0 position, highlighted in gray), ending aa position, the functional consequences of the methylation, and the references. AR: a potential substrate, methylation site not mapped.
