Ezh2 (Enhancer of Zeste Homolog 2, Polycomb group (PcG) Protein, ENX-1, EZH1, MGC9169)
Description:
EZH2, also known as ENX-1, 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. The human EZH2 gene was originally mapped to chromosome 212, but further studies showed that this is a pseudogene, and that EZH2 actually maps to chromosome 7q35 within the critical region for malignant myeloid disorders.
EZH2 and BMI-1 genes are co-expressed in Reed-Sternberg cells of Hodgkin’s disease. Co-expression 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 is also a marker that distinguishes prostate cancers at risk of lethal progression from indolent prostate cancer. EZH2 has been identified as a marker of aggressive breast cancer and a promoter of neoplastic transformation of breast epithelial cell.
