重组 UTX / KDM6A 蛋白 货号:E-31460
Recombinant UTX / KDM6A protein
背景资料:KDM6A (lysine (K)-specific demethylase 6A), also known as UTX (Ubiquitously Transcribed Tetratricopeptide Repeat, X Chromosome) is a protein that functions as a histone demethylase that preferentially demethylates di- and trimethylated lysine 27residues of histone H3, while it has no activity on monomethylated H3K27 residues. KDM6A plays a central role in posterior development by regulating HOX gene expression. Demethylation of lysine 27 is concomitant with methylation of lysine 4 of histone H3 and regulates the recruitment of the PRC1 complex and monoubiquitination of histone H2A.
产品描述:
Recombinant UTX / KDM6A (accession number NP_066963.2) was expressed in Sf9 cells and contains an N-terminal FLAG tag with an observed molecular weight of 158.8 kDa. The recombinant protein is >72% pure by SDS-PAGE.
产品应用:
Recombinant UTX / KDM6A is suitable for use in the study of enzyme kinetics, inhibitor screening, and selectivity profiling.
Specific Activity: H3K27me3 demethylase.
Histone Demethylase Assay Conditions: 50 mM HEPES pH 7.5, 0.02% Triton X100, 100 μM 2OG, 100 μM Ascorbate, 50 μM (NH4)2Fe(SO4)2·6H2O, 1 mM TCEP, 100 nM Recombinant UTX / KDM6A protein, and 3.3 μM H3K27me3 peptide at 2 hours at room temperature. MALDI-TOF was used for detection.
产品使用:
Full length recombinant UTX / KDM6A protein expressed in Sf9 cells at a concentration of 0.6 mg/ml in 25 mM HEPES, pH 7.5, 150 mM NaCl and 5% glycerol.
温度保存:
Lyophilized proteins can be stored at -20°C or -80°C, preferably desiccated. Recombinant proteins in solution are temperature sensitive and must be stored at -80°C to prevent degradation. Avoid repeated freeze/thaw cycles and keep on ice when not in storage.

关于5-hmC
5-hmC是近年来在动物组织中发现的,由胞嘧啶修饰而来。5-hmC在表观遗传学上的功能可能与5-甲基化胞嘧啶(5-mC)不同。尽管到现在为止还不确知其功能,有研究者猜测它在调控基因的表达与关闭过程中起着重要的作用。5-mC的发现让我们不得不重新评估DNA甲基信息,也不得不监测人类的健康组织和病理组织之间5-mC相对分布的差异。在EPI公司的MethylFlash技术之前,我们还没有发现任何直接的常规方法来检测5- hmC,以及区分5-hmC和5-mC
5-hmC 和 5-mC的区别
时下常用的DNA甲基化分析方法包括限制内切酶酶切和亚硫酸氢盐或MeDIP介导的MS-PCR和测序,这些技术都不适合用来检测5-hmC,因为它与5-mC事实上很难用这类方法区分开来。为了解决这个问题,EPIk研制了MethylFlash羟甲基化DNA定量试剂盒(荧光法)。本试剂盒提供了一种很经济的方法来检测5-羟甲基化胞嘧啶,并且区分5-hmC, 5-mC, 和 C,使得研究者能够重新评估他们的DNA甲基化信息,也能够在新样品中寻找DNA羟甲基化。 |
