EZH2

EZH2 is the catalytic subunit of PRC2, trimethylating H3K27 → gene silencing; EZH2 Y641 gain-of-function mutation in ~25% of follicular lymphoma and ~10% of DLBCL silences tumor suppressors including CDKN2A; tazemetostat (EZH2 inhibitor) is FDA-approved for EZH2-mutant FL.

Also known as: EZH2, enhancer of zeste homolog 2, PRC2, Polycomb repressive complex 2, H3K27me3, tazemetostat, EZH2 Y641, EZH2 inhibitor, histone methyltransferase
