Insertion of a Mi{Hto-WP} element within Sfp24Bd ( 2L:3 ,669,091 (+) -Release 6). The hostile takeover (hto) exon in the Mi{Hto-WP} element splices to the downstream Drgx exon 2. This results in a fusion protein being expressed under the control of Scer\UAS regulatory sequences in the Mi{Hto-WP} element. The fusion protein consists of 3 copies of the T:Zzzz\FLAG tag, the mCherry form of Disc\RFP, 9 amino acid linker sequence translated from the Drgx 5'UTR exon (LGPAAAGRG) and the Drgx coding sequence. Sfp24Bd and the nearby Sfp24Ba, Sfp24Bb and Sfp24Bc genes are not induced because they are transcribed in the reverse direction.
