Inaki;Arimondo, Paola B. research published 《 Identification of Chemical Probes Targeting MBD2》, the research content is summarized as follows. Epigenetics has received much attention in the past decade. Many insights on epigenetic (dys)regulation in diseases have been obtained, and clin. therapies targeting them are in place. However, the readers of the epigenetic marks are lacking enlightenment behind this revolution, and it is poorly understood how DNA methylation is being read and translated to chromatin function and cellular responses. Chem. probes targeting the methyl-CpG readers, such as the methyl-CpG binding domain proteins (MBDs), could be used to study this mechanism. We have designed analogs of 5-methylcytosine to probe the MBD domain of human MBD2. By setting up a protein thermal shift assay and an AlphaScreen-based test, we were able to identify three fragments that bind MBD2 alone and disrupt the MBD2-methylated DNA interactions. Two-dimensional NMR experiments and virtual docking gave valuable insights into the interaction of the ligands with the protein showing that the compounds interact with residues that are important for DNA recognition. These constitute the starting point for the design of potent chem. probes for MBD proteins.
554-01-8, 5-Methylcytosine is a methylated form of the nucleobase cytosine occurring predominantly in cytosine-phosphate-guanine (CpG) islands that are produced by DNA methyltransferases and may regulate gene expression. Like cytosine, the DNA sequence containing 5-methylcytosine (5-mC) is able to be replicated without error and 5-mC can pair with guanine in double stranded DNA. However, DNA sequences containing a high local concentration of 5-mC may be less transcriptionally active than areas with higher ratios of unmodified cytosine.
5-Methylcytosine belongs to the class of organic compounds known as hydroxypyrimidines. These are organic compounds containing a hydroxyl group attached to a pyrimidine ring. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. 5-Methylcytosine exists as a solid, slightly soluble (in water), and a very weakly acidic compound (based on its pKa). Within the cell, 5-methylcytosine is primarily located in the cytoplasm. 5-Methylcytosine can be biosynthesized from cytosine. Outside of the human body, 5-methylcytosine can be found in tea. This makes 5-methylcytosine a potential biomarker for the consumption of this food product.
5-methylcytosine is a pyrimidine that is a derivative of cytosine, having a methyl group at the 5-position. It has a role as a human metabolite. It is a member of pyrimidines and a methylcytosine. It derives from a cytosine.
5-Methylcytosine is a nucleic acid that is found in the DNA and RNA of the cell. It is an important component of methylation, which is the process by which a methyl group is added to a molecule. This process can lead to cellular transformation, a process that can cause cancer. 5-Methylcytosine has also been shown as a molecular pathogenesis factor in infectious diseases such as HIV and herpes simplex virus type 1. The presence of 5-methylcytosine in nuclear DNA has been detected by analytical techniques such as gas chromatography/mass spectrometry (GC/MS). There are many analytical methods, including GC/MS, that can be used to detect 5-methylcytosine in cellular nuclei., Recommanded Product: 4-Amino-5-methylpyrimidin-2(1H)-one
