摘要
DNA methylation in the form of 5-methylcytosine (SmC) is essential for normal development in mammals and influences a variety of biological processes, including transcriptional regulation, imprinting, and the maintenance of getumlic stability. The recent discovery of TET proteins, which oxidize 5mC to 5-hydroxymethylcytosine, 5-formylcytosine. and 5-carboxylcytosine, has changed our understanding of the process of DNA demethylat ion. Here, we summarize our current knowledge of the roles of DNA methylation and TET proteins in cell differentiation and function. The intensive research on this subject has so far focused primarily on embryonic stem (ES) cells and neurons. In addition, we summarize what is known about DNA methylation in T-cell function.
