Disordered N-Terminal DNMT3A Domain Is Required for Mouse Postnatal Development


ABSTRACT: DNA methyltransferase 3a (DNMT3A) plays a crucial role in multiple biological processes during mouse development. We report that the longer isoform DNMT3A1, but not the shorter DNMT3A2, is essential for mouse postnatal development. DNMT3A1 binds to and regulates bivalent developmental genes in the brain. The disordered N-terminal domain is required for DNMT3A1-regulated development, DNA methylation and gene expression in the nervous system. A potential ubiquitin-interacting motif (UIM) in the N-terminus may bind to histone H2AK119 ubiquitination, mediating the recruitment of DNMT3A1 to its targets. These data reveal the N-terminus as a necessary regulatory domain for DNMT3A1 chromatin occupancy and functions.
