|Application ||WB, IHC-P, IF, E|
|Other Accession||AAC50778, 19923202|
|Reactivity||Human, Mouse, Rat|
|Calculated MW||85271 Da|
|Application Notes||EZH1 antibody can be used for detection of EZH1 by Western blot at 1 - 2 µg/mL. Antibody can also be used for immunohistochemistry starting at 5 µg/mL. For immunofluorescence start at 20 µg/mL.|
|Target/Specificity||EZH1; Multiple isoforms of EZH1 are known to exist. EZH1 antibody is predicted to not cross-react with EZH2|
|Reconstitution & Storage||EZH1 antibody can be stored at 4℃ for three months and -20℃, stable for up to one year. As with all antibodies care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures.|
|Precautions||EZH1 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Polycomb group (PcG) protein. Catalytic subunit of the PRC2/EED-EZH1 complex, which methylates '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. Required for embryonic stem cell derivation and self-renewal, suggesting that it is involved in safeguarding embryonic stem cell identity. Compared to EZH2-containing complexes, it is less abundant in embryonic stem cells, has weak methyltransferase activity and plays a less critical role in forming H3K27me3, which is required for embryonic stem cell identity and proper differentiation.|
|Cellular Location||Nucleus. Note=Colocalizes with trimethylated 'Lys-27' of histone H3|

EZH1 Antibody: EZH1 was initially identified as a homolog of the drosophila Enhancer of Zeste through transcription mapping of chromosome 17q21. Both EZH1 and the related protein EZH2 can form complexes with the noncanonical Polycomb repressive complex-2 (PRC2) and maintain repressive chromatin, but the PRC2-EZH1 complex mediates methylation of histone H3. Both EZH1 and EZH2 are thought to function in the maintenance of embryonic stem cell pluripotency and plasticity and recently have been shown to be essential for hair follicle homeostasis and wound repair.
