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

5-methylcytosine is a major epigenetic modification that is sometimes called "the fifth nucleotide." However, our knowledge of how offspring inherit the DNA methylome from parents is limited. We generated nine single-base resolution DNA methylomes, including zebrafish gametes and early embryos.
