This article explores the complex interplay between the process of protein translation and DNA methylation, discussing their combined involvement in brain development. We will emphasize on DNA methylation and related proteins such as DNMTs, TETs, and MeCP2, the latter being the prototype of DNA methyl-binding proteins. Collectively, DNA methylation machinery may be involved in controlling the cell fate commitment of brain cells, as well as their neuronal and glial lineage specification. We aim to summarize current knowledge on the dynamics of protein translation, ribosome biogenesis, and relevant cellular pathways, including the mTOR signaling, in the context of brain development. Special attention is given to MeCP2 because of its unique role as an epigenetic factor that influences the chromatin states with a link to protein translation and its relevance to human disease. We also discuss the impact of DNA methylation-mediated chromatin regulation and protein translation in neurodevelopmental disorders. Our discussions include multi-omics techniques and integrative mechanisms that connect DNA methylation with protein translation.
