  1. Sex-lethal is a transcription factor that activates female-specific genes.
  2. Sex-lethal is a repressor of the transcription of male-specific genes.
  3. Sex-lethal controls the splicing of specific mRNAs such that certain proteins required for female development are produced only in females.
  4. Sex-lethal protein is equivalent to testosterone in mammals, in determining male development.
