Identification of the 1-methyladenine receptor

描述（由申请方提供）：拟定研究的目的是鉴定和表征海星（铜绿海星）中的卵母细胞成熟激素受体。该模型系统提供了显着的优势，比其他和一些方面可能是与哺乳动物卵母细胞共享。拟开展的工作旨在使用独特的基于同源性和基于功能表达克隆的方法串联鉴定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，以鉴定和表征该受体。使用这些新策略成功鉴定1-MA受体将代表任何物种中成熟诱导激素受体的第一个明确描述，并为用于鉴定其他物种（包括哺乳动物）中成熟激素受体的策略提供概念证明。已经分离出几种候选cDNA;将对这些和其他候选cDNA进行进一步的功能研究以确认身份，并进行卵母细胞成熟的必要性试验。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制的细节。

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.
