Structure of Drosophila and tephritid Sex-lethal (Sxl-D and Sxl-T in the Figure) and the Drosophila paralogue ssx. The Figure shows splice variants of Sxl-D, the position of translation start sites (>) and stop codons (*) as well as the position of the Sxl-specific and RRM protein domains following . The gene structure for Sxl-T is for indicative purposes only, as only exonic sequences are available and the exact position of introns is unknown.
