Encor Rabbit polyclonal to MeCP2
Methyl-CpG Binding Protein 2 (MeCP2) is a nuclear protein that is found to bind to symmetrical methylated CpG dinucleotide sequences. It is a transcriptional modulator that can alter gene expression epigenetically via binding to methylated DNA. It is involved not only in transcriptional silencing, but also in transcriptional activation, chromatin remodeling, and RNA splicing. Mecp2 is a X-chromosome-linked gene, highly expressed in neurons. The mutations of Mecp2 are linked to Rett syndrome (RTT) (2), which is a neurodevelopmental, autistic disorder that affects mainly females. Studies show that even the loss of a specific phosphorylation site of MeCP2 (e.g., S80, S421, and S424) disturbs normal maturation of the mammalian brain. Neuronal activity has been reported to trigger phosphorylation of MeCP2 at S421 in vitro and in vivo, which was further postulated to regulate activity-dependent gene transcription and neuronal spine maturation (3) (4). Mutation of the S80 phosphorylation site reduces MeCP2 association with chromatin at several euchromatic gene promoters, alters transcription of several genes that are potentially important for neuronal function (5).
