Methyl-CpG Binding Domain Protein 1 (MBD1), also known as Methyl-CpG-Binding Protein 1 (MECP2), is a 70 kDa chromatin-associated protein that binds to methylated DNA and participates in transcriptional repression. MBD1 is a member of the MBD family of proteins that interpret DNA methylation patterns and regulate gene expression. In the nervous system, MBD1 plays critical roles in neuronal development, synaptic plasticity, and cognitive function.

MBD1 is a transcriptional repressor that recognizes methylated CpG dinucleotides in DNA and recruits chromatin-modifying complexes to silence gene expression. The protein contains an MBD domain that binds methylated DNA, as well as transcription repression domains that interact with histone deacetylases and other chromatin modifiers. In the brain, MBD1 regulates genes important for neuronal differentiation, synaptic plasticity, and memory formation.
The MBD1 gene encodes a nuclear protein that is expressed throughout development and in adult tissues, with high expression in the brain. MBD1 is essential for proper neuronal function, as evidenced by studies showing that MBD1-deficient mice exhibit learning and memory deficits. In the context of neurodegeneration, MBD1 has been implicated in the epigenetic regulation of genes associated with Alzheimer's Disease and other disorders. Altered MBD1 function may contribute to the dysregulation of synaptic genes observed in neurodegenerative conditions.
