m6A DNA methylation Mettl3 Mettl3 KO Mice Mettl3 cKO Mice METTL3 and METTL14 in the METTL family are studied more than others.
The m6A modification mediated by METTL3 plays a significant role in biorhythm, DNA damage response (DDR),regulation of stem cell self-renewal and pluripotency, parent-zygote transformation, neuro-regulation and sex determination in drosophila,  various biological processes and ontogenesis development of eukaryotes such as early embryonic development of mice.
The knockout of Mettl3 can cause the death of mice embryo, and the in vivo biology function of Mettl3-mediated m6A RNA modification in tissue development is largely unknown in mammals. For germ cell-specific( (Vasa-Cre) Mettl3 knockout mice (Mettl3 cKO) model, the ablation of Mettl3 in germ cells severely inhibited spermatogonial differentiation and blocked the initiation of meiosis in mice, resulting in male infertility.
Specific inactivation of Mettl3 in the central nervous system (CNS) can cause severe dyskinesia or even death in mice during lactation.
m6A DNA methylation Mettl14 Mettl14 KO Mice Mettl14 cKO Mice Germ cell-specific Mettl3 or Mettl14 knockout with Vasa-Cre in mice can bring the loss of m6A, then cause proliferation of spermatogonial stem cells (SSCs) and translation dysfunction of differentiation-associated gene transcript, eventually result in the depletion of spermatogonial stem cells (SSCs).
Combined deletion of Mettl3 and Mettl14 will impair the translation of haploid-specific genes  for spermiogenesis, and finally result in spermatogenesis arrest.
Specificl inactivation of Mettl14 in central nervous system (CNS)in mice can cause severe impact on its cerebral cortical development.

All these 3 YTHDF proteins can influence the  m6A RNA DNA  methylation related basic biology process through integration and collaboration.
