CG31188 is a dicistronic gene. Data directly used to annotate the dicistronic gene model are shown in the black panel and the gene models generated from these data are shown in the cyan panel. Coding sequences are delineated by green vertical lines (starts of translation) and red vertical lines (stops of translation). Dicistronic genes (dark blue) were predicted when assembled cDNA sequencing reads or complete cDNA sequence (light and dark green) span two complete open reading frames (ORF1 and ORF2, shaded in cyan panel) that are separated by in-frame stop codons. There must be additional evidence supporting the existence of both predicted peptides. In the case of CG31188 on chromosome arm 3R, each of the two ORFs shares homology with proteins from other eukaryotes (orange) or Drosophila (red).
