A Drosophila male accessory gland protein that is a member of the serpin superfamily of proteinase inhibitors is transferred to females during mating.

Abstract:

:Accessory gland peptide 76A, (Acp76A), belongs to the serpin superfamily of proteins (serine protease inhibitors). Acp76A is a secreted protein synthesized only in the Drosophila melanogaster adult male accessory gland. Accumulation of the protein in males is first detected with polyclonal antibodies at 1 day after eclosion. The level of the protein in virgin males reaches a peak 5-8 days post-eclosion, and remains constant for at least 20 days. Upon mating the amount of Acp76A in males drops dramatically, but recovers by 24 h after mating. Immediately after mating the Acp76A is found in the female uterus. By 6 h after mating the amount of Acp76A detected in females is drastically reduced.
