WebMay 24, 2024 · EZH2 phosphorylation is majorly associated with the inhibition of its methyltransferase activity, leading to a decrease in the level of H3K27me3 [78, 79, 83]. Interestingly, phosphorylation at different sites of EZH2 is associated with distinct biological functions. EZH2 is phosphorylated on Thr311 by AMPK, and on Ser21 by AKT. WebOct 6, 2024 · Within the PRC2 complex, EZH2 (and to a lesser extent, EZH1) is the catalytic subunit responsible for methyltransferase activity. Both EZH proteins were observed to be phosphorylated, although EZH1 phosphorylation was shown to lead to degradation, while EZH2 phosphorylation led to reduced function (2, 3).
