A multigene family encoding male specific serum polypeptides (MSSPs) that show significant structural similarity to the family of insect odourant binding proteins, has been characterized in the medfly Ceratitis capitata . This family comprises seven members classified in three subgroups, MSSP‐α, MSSP‐β and MSSP‐γ. The genes of subgroups α and β are clustered in tandem in a 35‐kb genomic region, and present an exceptionally high degree of similarity not only in their coding but also in the surrounding regions, while the genes of the γ subgroup are drastically divergent. Although MSSPs are predominantly expressed in the male fat body, detailed expression studies suggest that individual members of this family are expressed in a distinct sex‐ and tissue‐specific manner.
