DESCRIPTION (provided by applicant): The goal of the proposed study is to identify and characterize the oocyte maturation hormone receptor in the starfish, Patina miniata. This model system offers significant advantages over others and some aspects may be shared with mammalian oocytes. The proposed work is designed to identify and characterize this receptor using unique homology based and functional expression cloning based approaches in tandem to identify and clone candidate cDNA(s) encoding the receptor for the maturation-inducing hormone, 1-methyladenine (1- MA). Successful identification of the 1-MA receptor using these novel strategies would represent the first definitive description of a maturation-inducing hormone receptor in any species and provide proof of concept for the strategy to be used for the identification of maturation hormone receptors in other species, including mammals. Several candidate cDNAs already have been isolated; these and additional candidates will be subjected to further functional studies to confirm identity and tests for necessity in oocyte maturation will be conducted. Eventually, studies will be conducted that are designed to elucidate the details of the molecular mechanism of signal transduction during oocyte maturation.

描述（由申请人提供）：拟议的研究的目的是识别和表征海星中Patina Miniata中的卵母细胞成熟激素受体。该模型系统比其他模型具有显着优势，并且某些方面可能与哺乳动物卵母细胞共享。拟议的工作旨在使用基于独特的同源性和功能性表达克隆的方法来识别和表征该受体的串联方法，以识别和克隆候选cDNA（S）编码成熟诱导激素的受体，1-甲基丹宁（1- MA）。使用这些新型策略成功鉴定1-MA受体将代表任何物种中诱导成熟激素受体的第一个确定描述，并提供概念证明，以便该策略用于鉴定其他物种（包括哺乳动物）中的成熟激素受体。已经隔离了几个候选cDNA。这些和其他候选者将进行进一步的功能研究，以确认身份和测试卵母细胞成熟的必要性。最终，将进行研究，旨在阐明卵母细胞成熟过程中信号转导的分子机理的细节。
