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）：拟议研究的目标是鉴定和表征海星 Patina miniata 中的卵母细胞成熟激素受体。该模型系统比其他模型系统具有显着的优势，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同源性的独特方法和基于功能表达克隆的方法来识别和表征该受体，以识别和克隆编码成熟诱导激素 1-甲基腺嘌呤 (1-MA) 受体的候选 cDNA。 。使用这些新策略成功鉴定 1-MA 受体将代表对任何物种中成熟诱导激素受体的首次明确描述，并为用于鉴定其他物种中成熟激素受体的策略提供概念证明。包括哺乳动物。一些候选 cDNA 已经被分离出来；这些和其他候选者将接受进一步的功能研究，以确认其身份，并进行卵母细胞成熟必要性测试。最终，将进行旨在阐明卵母细胞成熟过程中信号转导分子机制细节的研究。
