Total ENX-2 Cell-Based Colorimetric ELISA Kit
- 货号：KA3844C
- 应用：ELISA
- 种属：Human;Mouse
- 其他名称：
- Histone-lysine N-methyltransferase EZH1 (EC 2.1.1.43) (ENX-2) (Enhancer of zeste homolog 1)
- 背景：
- catalytic activity:S-adenosyl-L-methionine + histone L-lysine = S-adenosyl-L-homocysteine + histone N(6)-methyl-L-lysine.,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 EZH1-containing complexes, it is less abundant in embryonic stem cells and plays a less critical role in forming H3K27me3, which is required for embryonic stem cell identity and proper differentiation.,similarity:Belongs to the histone-lysine methyltransferase family. EZ subfamily.,similarity:Contains 1 SET domain.,subcellular location:Colocalizes with trimethylated 'Lys-27' of histone H3.,subunit:Component of the PRC2/EED-EZH1 complex, which includes EED, EZH1, SUZ12, RBBP4 and AEBP2. The PRC2/EED-EZH1 is less abundant than the PRC2/EED-EZH2 complex, has weak methyltransferase activity and compacts chromatin in the absence of the methyltransferase cofactor S-adenosyl-L-methionine (SAM).,
- 功能：
- chromatin organization, transcription, chromatin modification, regulation of transcription, chromosome organization,
- 细胞定位：
- Nucleus . Colocalizes with trimethylated 'Lys-27' of histone H3.
