早老素与阿尔茨海默病的发生有关,并在发育过程中促进LIN-12/Notch活性。所有早老蛋白都有多个疏水区域,理论上可以跨越一个膜,对膜拓扑结构的描述是推断早老蛋白功能机制的关键一步。以前,我们提出了一个八跨膜结构域的早老素模型,基于对秀丽隐杆线虫SEL-12早老素的研究。在这里,我们描述的实验,支持的观点,SEL-12的两个疏水区域的功能作为第七和第八跨膜结构域。此外,我们已经表明,人早老素1的行为像SEL-12早老素时,我们的方法进行分析。我们的研究结果提供了额外的实验支持早老素拓扑结构的八跨膜结构域模型。
Presenilins have been implicated in the genesis of Alzheimer’s disease and in facilitating LIN-12/Notch activity during development. All presenilins have multiple hydrophobic regions that could theoretically span a membrane, and a description of the membrane topology is a crucial step toward deducing the mechanism of presenilin function. Previously, we proposed an eight-transmembrane-domain model for presenilin, based on studies of theCaenorhabditis elegansSEL-12 presenilin. Here, we describe experiments that support the view that two of the hydrophobic regions of SEL-12 function as the seventh and eighth transmembrane domains. Furthermore, we have shown that human presenilin 1 behaves like SEL-12 presenilin when analyzed by our methods. Our results provide additional experimental support for the eight-transmembrane-domain model of presenilin topology.
