DNMT3

DNMT3A is a de novo DNA methyltransferase that catalyzes CpG methylation and establishes epigenetic patterns required for mammalian development, cellular differentiation, genomic imprinting, and stable gene regulation[1][1]. Mechanistically, DNMT3A functions within the DNA methylation machinery that creates new methylation marks on previously unmethylated DNA, thereby contributing to transcriptional repression and maintenance of cellular identity[1][2]. During development, DNMT3A and DNMT3B share partially overlapping functions; however, locus-specific analyses demonstrated that DNMT3A is uniquely required for de novo methylation of Polycomb group target developmental genes, whereas DNMT3B shows distinct targeting preferences, including a dominant role at specific X-chromosomal regions[2]. In disease models, disruption of DNMT3A alters epigenetic regulation and impairs hematopoietic stem cell differentiation, leading to enhanced stem cell self-renewal and abnormal lineage commitment[3]. Consistent with these findings, DNMT3A is among the most frequently mutated epigenetic regulators in acute myeloid leukemia, highlighting its importance in hematopoietic homeostasis and leukemogenesis[2][4]. Compared with related isoforms, DNMT3A1 and DNMT3A2 display distinct genomic localization patterns; notably, DNMT3A1 preferentially localizes to methylated shores of bivalent CpG island promoters and contributes to DNA methylation fidelity at these regulatory regions[7]. For experimental applications, DNMT3A serves as a widely used model for investigating de novo DNA methylation, epigenetic inheritance, developmental gene regulation, and mutation-driven hematologic malignancies[2][3][7].
