| Specificity/Sensitivity | Phospho-Ezh2 (Thr345) (E7T7K) Rabbit mAb recognizes endogenous levels of total Ezh2 protein only when phosphorylated at Thr345. This antibody may detect a band of unknown origin around 135 kDa. |
| Species Reactivity | Human, Mouse, Rat, Monkey |
| Source/Purification | Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Thr345 of human Ezh2 protein. |
| Background | The polycomb group (PcG) proteins are involved in maintaining the silenced state of several developmentally regulated genes and contribute to the maintenance of cell identity, cell cycle regulation, and oncogenesis (1,2). Enhancer of zeste homolog 2 (Ezh2), a member of this large protein family, contains four conserved regions including domain I, domain II, and a cysteine-rich amino acid stretch that precedes the carboxy-terminal SET domain (3). The SET domain has been linked with histone methyltransferase (HMTase) activity. Moreover, mammalian Ezh2 is a member of a histone deacetylase complex that functions in gene silencing, acting at the level of chromatin structure (4). Ezh2 complexes methylate histone H3 at Lys9 and 27 in vitro, which is thought to be involved in targeting transcriptional regulators to specific loci (5). Ezh2 is deregulated in various tumor types, and its role, both as a primary effector and as a mediator of tumorigenesis, has become a subject of increased interest (6).Ezh2 is phosphorylated on Thr345 by cyclin-dependent kinase 1 (CDK1), which increases targeting of Ezh2 to its target loci and promotes methylation of H3 at Lys27 (7,8). This activated form of Ezh2 may deposit initial H3K27me3 marks onto newly synthesized daughter strands of DNA during replication (9). In addition, phosphorylation of Thr345 affects Ezh2 stability by promoting its ubiquitination and subsequent degradation (9). |
