Abstract
DNA methylation is an epigenetically inherited chemical modification that is associated with transcriptional silencing and is essential for mammalian development. The DNA methylation signal is read out by methyl-CpG binding proteins (MBPs) that specifically bind to methylated DNA. Three structurally divergent families of MBPs have been identified so far: the MBD family, the SRA family and a family of proteins with Zinc fingers. In this review, we describe how the distinct families of methyl-CpG binding proteins have evolved, how they each recognize and maintain the DNA methylation mark, and finally how they turn this mark into biological effect.
