GeneID: 17257 Mouse MECP2

Swiss-port # Q9Z2D6 Mouse Methyl-CpG-binding protein 2

Gene Symbol MECP2
Gene Full Name methyl CpG binding protein 2
Background DNA methylation is the major modification of eukaryotic genomes and plays an essential role in mammalian development. Human proteins MECP2, MBD1, MBD2, MBD3, and MBD4 comprise a family of nuclear proteins related by the presence in each of a methyl-CpG binding domain (MBD). Each of these proteins, with the exception of MBD3, is capable of binding specifically to methylated DNA. MECP2, MBD1 and MBD2 can also repress transcription from methylated gene promoters. In contrast to other MBD family members, MECP2 is X-linked and subject to X inactivation. MECP2 is dispensible in stem cells, but is essential for embryonic development. MECP2 gene mutations are the cause of most cases of Rett syndrome, a progressive neurologic developmental disorder and one of the most common causes of mental retardation in females.

Function Chromosomal protein that binds to methylated DNA. It can bind specifically to a single methyl-CpG pair. It is not influenced by sequences flanking the methyl-CpGs. Mediates transcriptional repression through interaction with histone deacetylase and the corepressor SIN3A. Binds both 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC)-containing DNA, with a preference for 5-methylcytosine (5mC). [UniProt]
Calculated MW 52 kDa
PTM Phosphorylated on Ser-423 in brain upon synaptic activity, which attenuates its repressor activity and seems to regulate dendritic growth and spine maturation.

    Immunocytochemistry: Mouse brain section, which was cut at 45 µM on a vibratome after perfusion with 4% parformaldehyde and overnight fixation, was stained with ARG10762 anti-MeCP2 phospho (Ser421) antibody [2E2] at 1:1000 dilution. Phospho-MeCP2 at S421 was mainly associated with  methylated DNA  in  nucleus of  activated neuron cells  (red). Blue shows DAPI staining of nuclear DNA. .
