MGI Phenotype |
FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a member of a family of nuclear proteins related by the presence of a methyl-CpG binding domain (MBD). These proteins are capable of binding specifically to methylated DNA, and some members can also repress transcription from methylated gene promoters. This protein contains multiple domains: MBD at the N-terminus that functions both in binding to methylated DNA and in protein interactions; several CXXC-type zinc finger domains that mediate binding to non-methylated CpG dinucleotides; transcriptional repression domain (TRD) at the C-terminus that is involved in transcription repression and in protein interactions. Numerous alternatively spliced transcript variants encoding different isoforms have been noted for this gene.[provided by RefSeq, Feb 2011] PHENOTYPE: Homozygous null exhibited defects in adult hippocampal neurogenesis and function. Spatial learning was also impaired in mutant mice. [provided by MGI curators]

Protein Function and Prediction |
Mbd1 is a factor in DNA methylation-mediated epigenetic gene regulation (1;2). Mbd1 expression is important in brain development and cognitive functions (1). Mbd proteins bind to methyl-CpG pairs to repress transcription (2).
|
Expression/Localization |
Mbd1 is expressed in both neural progenitors and neurons (3).
|
Background |
Mbd1tm1Fhg/tm1Fhg; MGI:2664084
129S4/SvJae-Mbd1tm1Fhg
Homozygous null animals exhibit abnormal neuron differentiation, reductions in hippocampal neurogenesis, decreased brain weight, and reduced hippocampal function (3). Adult homozygotes are healthy and display no significant deficits in motor coordination or locomotor activity, although spatial learning is impaired (3). Homozygous animals also have aneuploidy, chromosomal instability, and chromosomal breakage; no chromosomal translocation was detected (3).
Mbd1tm1Fhg/tm1Fhg; MGI:2664084
129S4 x C57BL/6
Homozygous mice exhibit no gross abnormality and have nearly normal lifespan (1). However, they exhibit several core deficits frequently associated with autism, including reduced social interaction, learning deficits, anxiety, defective sensory motor gating, depression and abnormal brain serotonin activity (1).
