SignificanceWe found exitrons (exonic introns) in four Odorant receptor (Or) genes of Drosophila. Exitrons are sequences that can be spliced from within a protein-coding exon, thereby altering the encoded protein. We are unaware of previous reports of exitrons in Drosophila. Removal of the exitron from the pheromone receptor gene Or88a creates a non-coding transcript.
