anti-5-Methylcytosine, Rabbit Monoclonal (RM231)

5-Methylcytosine is a methylated form of the DNA base cytosine that regulates gene transcription and is involved in epigenetics. It is one of the best known epigentic modifications. This methylation typically occurs at cytosine in CpG dinucleotides in vertebrates. When cytosine is methylated, the DNA maintains the same sequence, but the expression of methylated genes can be altered. 5-Methylcytosine is a very important repressor of transcription in the genome. When present in promoters, 5-Methylcytosine is associated with stable, long-term transcriptional silencing. This may occur by either blocking positive transcription factors, or promoting the binding of negative ones.
