Function
Polycomb group (PcG) protein. Catalytic subunit of the PRC2/EED-EZH2 complex, which methylates 'Lys-9' and 'Lys-27' of histone H3, leading to transcriptional repression of the affected target gene. Able to mono-, di- and trimethylate 'Lys-27' of histone H3 to form H3K27me1, H3K27me2 and H3K27me3, respectively. Compared to EZH2-containing complexes, it is more abundant in embryonic stem cells and plays a major role in forming H3K27me3, which is required for embryonic stem cell identity and proper differentiation. The PRC2/EED-EZH2 complex may also serve as a recruiting platform for DNA methyltransferases, thereby linking two epigenetic repression systems. Genes repressed by the PRC2/EED-EZH2 complex include HOXC8, HOXA9, MYT1, CDKN2A and retinoic acid target genes. -
Tissue specificity
Expressed in many tissues. Overexpressed in numerous tumor types including carcinomas of the breast, colon, larynx, lymphoma and testis. -
Sequence similarities
Belongs to the histone-lysine methyltransferase family. EZ subfamily.
Contains 1 SET domain. -
Developmental stage
Expression decreases during senescence of embryonic fibroblasts (HEFs). Expression peaks at the G1/S phase boundary. -
Post-translational
modificationsPhosphorylated by AKT1. Phosphorylation by AKT1 reduces methyltransferase activity. -

Chromatin was prepared from MDA-MB-231 cells according to the Abcam X-ChIP protocol. Cells were fixed with formaldehyde for 10 minutes. The ChIP was performed with 25µg of chromatin, 5µg of ab191250 (red), and 20µl of Anti rabbit IgG sepharose beads. 5μg of rabbit normal IgG was added to the beads control (grey). The immunoprecipitated DNA was quantified by real time PCR (Sybr green approach).

Predicted band size: 85 kDa
Observed band size: 90 kDa why is the actual band size different from the predicted?Merged signal (red and green). Green - ab191250 observed at 93 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab191250 was shown to specifically recognize KMT6/EZH2 in wild-type HAP1 cells along with additional cross-reactive bands. No band was observed when KMT6/EZH2 knockout samples were examined. Wild-type and KMT6/EZH2 knockout samples were subjected to SDS-PAGE. ab191250 and ab8245 (loading control to GAPDH) were diluted at 1/1000 and 1/10,000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10,000 dilution for 1 hour at room temperature before imaging.
