Male-derived accessory gland proteins (Acps) are transferred to the female reproductive tract during mating and affect female reproductive maturation and behavior. Some Acps subsequently enter the female hemolymph. We hypothesized that humoral proteases are the primary effectors of Acp bioactivity by processing (activating) and/or degrading them. To test this hypothesis we examined the fate of one Acp, Drosophila melanogaster Sex Peptide (Acp70A, DrmSP), which possesses several putative serine… CONTINUE READING
