WebJun 10, 2008 · Although inactive as an enzyme, knockout experiments have revealed that Dnmt3L is essential for the establishment of maternal methylation imprints during oogenesis, and for the methylation of retrotransposons, satellites repeats and some imprinted genes during spermatogenesis ( 12, 15–19 ). WebTET proteins oxidize 5-methylcytosine in DNA to 5-hydroxymethylcytosine and other oxidation products. We found that simultaneous deletion of Tet2 and Tet3 in mouse CD4 + CD8 + double-positive thymocytes resulted in dysregulated development and proliferation of invariant natural killer T cells (iNKT cells).
