Schematic of the foraging gene and associated features. The D. melanogaster foraging gene has four promoters that produce 21 transcripts and nine open reading frames (ORFs). The transcription start sites (pr1–4, up-and-right arrows) and transcription end site (AAA) were identified with rapid amplification of cDNA ends (RACE). The splicing patterns of the transcripts were identified by sequencing full-length cDNAs. Exons (blue boxes) are annotated along the locus (double black line) with the transcripts below. UTRs (gray boxes), ORFs (black boxes), cGMP-binding domains (yellow), ATP-binding domain (pink), and kinase domains (red) are also annotated. RA through RK were previously annotated on FlyBase.
