Gene Information

human ... EZH2(2146)

General description

EZH2 (enhancer of zeste homologue 2), also known as Enx1, is a member of the polycomb group of proteins and is involved in cell cycle regulation. EZH2 represses transcription via trimethylation of histone H3 on Lys27 (H3K27) as indicated by the fact that RNAi-mediated knockdown of EZH2 resulted in a loss of H3K27 trimethylation. EZH2 is ubiquitously expressed during early embryo genesis, and becomes restricted to the central and peripheral nervous systems and sites of fetal hematopoiesis during later development. In the adult, EZH2 is restricted to the spleen, testis, and placenta. EZH2 and BMI-1 genes are coexpressed in Reed-Sternberg cells of Hodgkin’s disease. Coexpression of BMI-1 and EZH2 is also associated with cycling cells and degree of malignancy in B-cell non-Hogkin’s lymphoma. EZH2 is involved in the progression of prostate cancer, and has been identified as a marker of aggressive breast cancer. Two transcript variants encoding distinct isoforms have been identified for this gene.

Enhancer of zeste 2 (EZH2) promotes prostate cancer progression. We hypothesized that increased EZH2 expression is associated with postradiotherapy metastatic disease recurrence, and may promote radioresistance. EZH2 expression was investigated using immunohistochemistry in diagnostic prostate biopsies of 113 prostate cancer

The ATRX ATP-dependent chromatin remodelling/helicase protein associates with the DAXX histone chaperone to deposit histone H3.3 over repetitive DNA regions. Because ATRX-protein interactions impart functions, such as histone deposition, we used proximity-dependent biotinylation (BioID) to identify proximal associations for ATRX.
