DESCRIPTION (provided by applicant): The identification of interacting male-female reproductive proteins is imperative for a molecular understanding of fertilization. Generally, the molecular descriptions have relied upon studies of male reproductive proteins. This research proposal is aimed at characterizing interacting male- female reproductive proteins in abalone, a system with for which many of the molecular details of fertilization are well established and one that serves as a model for the study of reproductive molecules and evolution of species-specific fertilization. Three specific aims relating to abalone are proposed: Aim 1. Biochemical analysis of interactions among gamete recognition proteins. Aim 2. Molecular description of VE supramolecular structure through analysis of ZP glycoprotein interactions. Aim 3. Abalone sperm proteome and functional analysis of a newly discovered novel gamete recognition protein. The research proposed is innovative in that it is highly integrative, utilizing genomic, proteomic, biochemical, and computational methods. This work will test for evidence of direct functional interactions between sperm and egg molecules. The functional specificity sperm-egg interaction will be further investigated. Together these research aims represent a significant advancement in our understanding of the molecular interactions between sperm and egg, the evolutionary dynamics of genes encoding sperm/egg proteins, and will contribute to a broader understanding of the function and evolution of reproductive genes.

描述（由申请人提供）：相互作用的男性-女性生殖蛋白的鉴定对于受精的分子理解是必要的。一般来说，分子描述依赖于对雄性生殖蛋白的研究。这项研究计划旨在表征鲍鱼中相互作用的雄性-雌性生殖蛋白，该系统已充分确定了受精的许多分子细节，并且可作为研究生殖分子和物种特异性进化的模型。施肥。提出了与鲍鱼相关的三个具体目标： 目标 1. 配子识别蛋白之间相互作用的生化分析。目标 2. 通过分析 ZP 糖蛋白相互作用对 VE 超分子结构进行分子描述。目标 3.鲍鱼精子蛋白质组和新发现的新型配子识别蛋白的功能分析。该研究的创新之处在于它是高度集成的，利用了基因组、蛋白质组、生物化学和计算方法。这项工作将测试精子和卵子分子之间直接功能相互作用的证据。精卵相互作用的功能特异性将得到进一步研究。这些研究目标共同代表了我们对精子和卵子之间的分子相互作用、编码精子/卵子蛋白的基因进化动力学的理解的重大进步，并将有助于更广泛地理解生殖基因的功能和进化。
