Sex peptide-SPR-serotonin signaling regulates mating-induced Sex peptide replenishment in Drosophila, suggesting an ancestral role in males

Ryo Hoshino, Yasuhiro Kozono, Ryoya Tanaka, Hsin-Kuang Lin, Tomotsune Ameku, 大弘丁, Tsunaki Asano, Azusa Kamikouchi, Yuko Shimada‐Niwa, Akira Nakamura, Takeshi Awasaki, Ryusuke Niwa

This study identifies a male-specific role for SP-SPR signaling in regulating mating-induced Sex peptide replenishment in Drosophila, suggesting an ancestral function before its known role in female post-mating responses.
