Application

5-Methylcytosine hydrochloride has been used as standard in high performance liquid chromatography (HPLC) for the estimation of global methylation rates. It has also been used in high-resolution mass spectroscopic analysis.
5-Methylcytosine is used in studies of DNA methylation processes (epigenetics).

Biochem/physiol Actions

5-Methylcytosine mediates gene expression, genomic imprinting and inhibition of transposable elements. It is closely associated with translational fidelity and tRNA recognition.

5-Hydroxymethylcytosine (5-hmC) was recently identified as a relatively frequent base in eukaryotic genomes. Its physiological function is still unclear, but it is supposed to serve as an intermediate in DNA de novo demethylation. Using X-ray diffraction, we solved five structures

Previous studies have revealed that mouse primordial germ cells (PGCs) undergo genome-wide DNA methylation reprogramming to reset the epigenome for totipotency. However, the precise 5-methylcytosine (5mC) dynamics and its relationship with the generation of 5-hydroxymethylcytosine (5hmC) are not clear. Here
