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. Interacts with FNBP3. Interacts with CDKL5. Present in all adult somatic tissues tested. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
Protein type: Transcription, coactivator/corepressor
Molecular Function: DNA binding; double-stranded methylated DNA binding; methyl-CpG binding; protein binding; protein domain specific binding; protein N-terminus binding; transcription corepressor activity
Biological Process: locomotory behavior; negative regulation of transcription from RNA polymerase II promoter; negative regulation of transcription, DNA-dependent; response to radiation
