enhancer of zeste homolog 2 (Drosophila)
EZH2 (Enhancer of Zeste Homolog 2) is a gene that encodes a protein which is a key component of the Polycomb Repressive Complex 2 (PRC2). This complex is involved in the regulation of gene expression through histone methylation, specifically the trimethylation of histone H3 at lysine 27 (H3K27me3), which leads to transcriptional repression of target genes.
EZH2 is often overexpressed in various types of cancers, including breast, prostate, and lymphoma. This overexpression can lead to the silencing of tumor suppressor genes, contributing to uncontrolled cell proliferation and survival.
EZH2 is biology-first; its biomarker value is a readout of epigenetic state.
