Vertebrates communicate through pheromones, which favor biological regulations within each species. Aphrodisin, a protein belonging to the lipocalin superfamily, found in hamster vaginal secretions, is detected by the male accessory olfactory system and induces or facilitates its copulatory behavior. Although much is known about aphrodisin structure, the question of whether aphrodisin bears itself the pheromonal function or is simply a carrier for hydrophobic small pheromones has not been definitely solved. Arguments based on use of recombinant aphrodisin deprived of any natural ligand and its capability to convey hamster pheromonal compounds will be discussed, together with progresses concerning putative natural ligand(s).
