Sequence-selective osmium oxidation of DNA: efficient distinction between 5-methylcytosine and cytosine.
5-Methylcytosine was distinguished from cytosine using the large difference of their osmium oxidation rates, and this reaction was applied to detection of the cytosine methylation status at a specific site of a long sequence using the formation of a bulge structure by hybridization with a guide DNA.
متن کاملMBD3L2 promotes Tet2 enzymatic activity for mediating 5-methylcytosine oxidation.
Ten-eleven translocation (Tet) proteins are key players involved in the dynamic regulation of cytosine methylation and demethylation. Inactivating mutations of Tet2 are frequently found in human malignancies, highlighting the essential role of Tet2 in cellular transformation. However, the factors that control Tet enzymatic activity remain largely unknown. Here, we found that methyl-CpG-binding ...
متن کاملMechanisms and functions of Tet protein-mediated 5-methylcytosine oxidation.
Ten-eleven translocation 1-3 (Tet1-3) proteins have recently been discovered in mammalian cells to be members of a family of DNA hydroxylases that possess enzymatic activity toward the methyl mark on the 5-position of cytosine (5-methylcytosine [5mC]), a well-characterized epigenetic modification that has essential roles in regulating gene expression and maintaining cellular identity. Tet prote...
متن کاملTET proteins and 5-methylcytosine oxidation in the immune system.
DNA methylation in the form of 5-methylcytosine (5mC) is essential for normal development in mammals and influences a variety of biological processes, including transcriptional regulation, imprinting, and the maintenance of genomic stability. The recent discovery of TET proteins, which oxidize 5mC to 5-hydroxymethylcytosine, 5-formylcytosine, and 5-carboxylcytosine, has changed our understandin...
متن کاملHighly selective detection of 5-methylcytosine using photochemical ligation.
We report the nonenzymatic detection of 5-methylcytosine by using template-directed photoligation through 5-cyanovinyl-2'-deoxyuridine ((C)U) with high selectivity and present a new methylation detection method using a photoligation-based DNA chip assay.
