Project description:Dnmt2 and NSun2 are (cytosine-5) RNA methyltransferases. Using CRISPR/Cas9 we created null mutations in Dnmt2 and NSun2 genes in Drosophila melanogaster. We also ectopically expressed a wild type and catalytically inactive Dnmt2 form in the Dnmt2 mutant background. RNA bisulfite sequencing was used to follow RNA methylation at partical tRNA substrates.
Project description:dG9a-depletion decreases the starvation resistance in the adult stage of Drosophila melanogaster. To determine which genes are regulated by dG9a under starvation stress, we examined mRNA levels by performing RNA-sequence analysis using 0 h and 12 h starved dG9a null mutant and wild type as a control.
