Abstract

P element transposition in Drosophila melanogaster is limited to the germ line because the third intron (the ORF2-ORF3 intron) of the P element transcript is spliced only in germ line cells. We describe a systematic search for P element sequences that are required to regulate the splicing of the ORF2-ORF3 intron. We have identified three adjacent mutations that abolish the germ line specificity and allow splicing of this intron in all tissues. These mutations define a 20-base regulatory region located in the exon, 12 to 31 bases from the 5' splice site. Our data show that this cis-acting regulatory sequence is required to inhibit the splicing of the ORF2-ORF3 intron in somatic cells.
