question: Which is the major RNA editing enzyme in Drosophila melanogaster?
answer: Adenosine deaminases that act on RNA [adenosine deaminase, RNA specific (ADAR)] catalyze the site-specific conversion of adenosine to inosine in primary mRNA transcripts. The ADAR RNA editing enzyme controls neuronal excitability in Drosophila melanogaster. TIRs were deduced to form dsRNAs as a putative target of ADAR. Genetic Determinants of RNA Editing Levels of ADAR Targets in Drosophila melanogaster. RNA editing usually affects only a fraction of expressed transcripts and there is a vast amount of variation in editing levels of ADAR (adenosine deaminase, RNA-specific) targets.
