This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. A recurring observation in the study of reproductive proteins is their rapid, adaptive evolution. This phenomenon occurs in organisms as diverse as diatoms and humans. The long-term goal of our research is to understand the diversity of reproductive proteins and the functional consequences of their divergence, which could involve problems in fertility and speciation due to a mismatch of sperm-egg recognition molecules. We work with a variety of organisms, including Drosophila, abalone (Haliotis), and mammals. A common theme throughout our research is identifying genes subjected to positive selection (adaptive evolution), indicating potentially functionally important candidate genes.

这个子项目是利用资源的许多研究子项目之一。 由NIH/NCRR资助的中心拨款提供。对子项目的主要支持 子项目的首席调查员可能是由其他来源提供的， 包括美国国立卫生研究院的其他来源。为子项目列出的总成本可能 表示该子项目使用的中心基础设施的估计数量， 不是由NCRR赠款提供给次级项目或次级项目工作人员的直接资金。 生殖蛋白质研究中的一个反复出现的现象是它们的快速、适应性进化。这种现象发生在硅藻和人类等各种生物体中。我们研究的长期目标是了解生殖蛋白的多样性及其分化的功能后果，这可能涉及由于精子-卵子识别分子不匹配而导致的生育和物种形成问题。 我们与各种生物打交道，包括果蝇、鲍鱼和哺乳动物。我们整个研究的一个共同主题是识别经历正向选择(适应性进化)的基因，表明潜在的功能重要的候选基因。
