摘要
昆虫雄性附腺蛋白是精液蛋白的主要来源,对雌雄虫生殖过程具有重要生理功能,按功能可分为精包结构蛋白和功能蛋白两类。精包结构蛋白参与精包的形成:功能蛋白在交配过程中随精子一起转移到雌虫体内,导致雌虫行为和生理的深刻变化,如降低雌虫再交配率、提高产卵量、促进精子转移、储存和竞争等。随着对昆虫雄性附腺功能蛋白研究的深入,特别对果蝇附腺功能蛋白的详细研究,从分子水平上闸述蛋白质序列与功能的关系,明确其作用机制,可为进一步阐明昆虫生殖和进化机制等提供新依据。
Insect male accessory gland proteins （IMAGPs） are major part of the seminal fluid proteins, and have important effects on the reproductive process of males and females. This kind of protein can be divided into two types, one is the spermatophorin, another is the functional protein. The spermatophorins are transferred into the female sperm receptive organs and take part in the forming process of the spermatophore. During mating, the functional proteins transferred with the sperm can decrease female receptivity, increase egg production, and promote sperm storage and competition. The MAG functional proteins, especial the proteins in the Drosophila have been studied in detail. Studies on molecular structure and reproductive function of male accessory gland proteins help to elucidate the mechanism at the molecular level. The progress on the functional proteins should provide a new insight to account for the role of insect reoroduction and the evolutionarv mechanism.
