Antigen/Purification: ExpandCollapse

The antigen is  a phosphopeptide corresponding to amino acid residues surrounding the phospho-Ser421 of MeCP2 (Methyl-CpG Binding Protein 2) protein.

The antibody is prepared from rabbit serum by affinity purification via sequential chromatography on phospho- and dephospho- peptide affinity columns.

Biological Significance: ExpandCollapse

MeCP2 (Methyl-CpG Binding Protein 2) is a chromosomal protein that binds to methylated DNA. It can bind specifically to a single methyl-CpG pair and is not influenced by sequences flanking the methyl-CpGs. MeCP2 has been shown to mediate transcriptional repression through interaction with histone deacetylase and the corepressor SIN3A (Nan et al., 1998). Defects in MeCP2 are the cause of Rett syndrome (RTT) (Amir et al., 1999). RTT is an X-linked dominant disease; it is a progressive neurologic developmental disorder and one of the most common causes of mental retardation in females. Recent studies have reported a new phosphorylation site at Ser421. Phosphorylation and dephosphorylation of this site may be involved in regulation of behavioral responses to chronic antidepressant treatment (Hutchinson et al., 2012).

100 µl in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol. Adequate amount of material to conduct 10-mini Western blots.

Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.

MeCP2 ser421 antibody
Western blot of mouse whole brain lysate showing specific immunolabeling of the ~55 kDa truncated MeCP2 protein phosphorylated at Ser421 in the first lane (-). Phosphospecificity is shown in the second lane (+) where immunolabeling is blocked by preadsorption of the phosphopeptide used as the antigen, but not by the corresponding non-phosphopeptide (not shown).
