U.S.-France Cooperative Research: Molecular Mechanism of Homologous Pairing and DNA Strand Exchange

这项为期三年的美法基因重组合作研究奖项涉及加州大学戴维斯分校的斯蒂芬·科瓦尔奇科夫斯基、阿兰·尼古拉斯、玛丽·杜特里克斯和法国巴黎居里研究所的弗朗西斯·法布雷。该奖项为科瓦尔奇科夫斯基博士和一名研究生提供旅费和生活费。他们研究的目的是调查DNA链的同源配对和随后的交换。这一过程是由一类独特的蛋白质介导的，以来自大肠杆菌的原型RecA蛋白和来自酿酒酵母的新的RAD51蛋白为代表。这位美国研究人员将重组的物理和生化方面的专业知识带到了这次合作中。这一点得到了法国在分子遗传学方面的专业知识的补充。该项目将促进对基因重组所涉及的生物过程的基本理解，包括导致有害基因组重排的异常过程。

This three-year award for U.S.-France cooperative research on genetic recombination involves Stephen Kowalczykowski of the University of California at Davis, Alain Nicolas, Marie Dutreix, and Francis Fabre of the Institut Curie in Paris, France. The award provides travel support and living expenses to Dr. Kowalczykowski and a graduate student. The objective of their research is to investigate homologous pairing and subsequent exchange of DNA strands. This process is mediated by a unique class of proteins represented by the prototypic RecA protein from Escherichia coli and by the new Rad51 protein from Saccharomyces cerevisiae. The U.S. investigator brings to this collaboration expertise in the physical and biochemical aspects of recombination. This is complemented by French expertise in molecular genetics. The project will advance fundamental understanding of the biological processes involved in genetic recombination, including aberrant processes that lead to deleterious genomic rearrangements.
