中文摘要
甘氨酸受体对神经系统功能很重要。这些受体由排列在中心离子传导孔周围的5个α和β亚基组成。亚基化学计量(即α亚基和β亚基的数量)和排列(即亚基顺序)是未知的。该项目的第一个目标是使用系绳子单元定义这些参数。第二个目标是利用拴系亚基以前所未有的分辨率探测甘氨酸和锌结合位点的结构和功能。该结果将为甘氨酸受体的结构和功能提供重要的新信息。
英文摘要
Glycine receptors are important for nervous system function. These receptors comprise a mixture of 5 alpha and beta subunits arranged around a central ion-conducting pore. The subunit stoichiometry (i.e., numbers of alpha and beta subunits) and arrangement (i.e., subunit order) are unknown. The first aim of this project is to define these parameters using tethered subunits. The second aim is to use the tethered subunits to probe the structure and function of glycine and zinc binding sites at an unprecedented level of resolution. The results will provide crucial new information concerning glycine receptor structure and function.
