Mating Based Split-ubiquitin Assay for Detection of Protein Interactions

[Abstract]  The mating based split-ubiquitin (mbSUS) assay is an alternative method to the classical yeast two-hybrid system with a number of advantages. The mbSUS assay relies on the ubiquitin-degradation pathway as a sensor for protein-protein interactions, and it is suitable for the determination of interactions between full-length proteins that are cytosolic or membrane-bound. Here we describe the mbSUS assay protocol which has been used for detecting the interaction between K+ channel and SNARE proteins (Grefen et al., 2010 and 2015; Zhang et al., 2015 and 2016) [摘要]  基于交配的分ubiquitin(mbSUS)测定是具有许多优点的经典酵母双杂交系统的替代方法。 mbSUS测定依赖于泛素降解途径作为蛋白质 - 蛋白质相互作用的传感器,并且它适用于测定细胞溶质或膜结合的全长蛋白质之间的相互作用。在这里,我们描述了已经用于检测K + 通道和SNARE蛋白之间的相互作用的mbSUS测定方案(Grefen等人,2010和2015; Zhang 等等,2015和2016)

背景 图1是mbSUS测定的概况。泛素部分被分成两半,N末端半突变(NubG)以避免重组。泛素部分(Cub)的C末端一半与转录报告基因复合物PLV(Protein A-LexA-VP16)连接。两种蛋白质(X和Y)分别与NubG和CubPLV融合产生蛋白质 - 蛋白质相互作用分析系统。转化后,酵母菌株THY.AP5含有NubG-X融合蛋白,而酵母菌株THY.AP4含有Y-CubPLV融合蛋白。在交配后,在二倍体酵母中,如果蛋白质X和Y彼此相互作用,则将重新组装功能性泛素,这导致PLV的切割。释放的转录蛋白复合物PLV可以开启报告基因(ADE2,HIS3),并允许酵母生长在选择性培养基上。

Single-step Marker Switching in Schizosaccharomyces pombe Using a Lithium Acetate Transformation Protocol

[Abstract]  The ability to utilize different selectable markers for tagging or mutating multiple genes in Schizosaccharomyces pombe is hampered by the historical use of only two selectable markers, ura4+ and kanMX6; the latter conferring resistance to the antibiotic G418 (geneticin). More markers have been described recently, but introducing these into yeast cells often requires strain construction from scratch. To overcome this problem we and other groups have created transformation cassettes with flanking homologies to ura4+ and kanMX6 which enable an efficient and time-saving way to exchange markers in existing mutated or tagged fission yeast strains.

Here, we present a protocol for single-step marker switching by ...
[摘要]  利用不同的选择标记来标记或突变粟酒裂殖酵母中的多个基因的能力受到仅仅两种可选择标记的历史使用的阻碍,即 +和 kanMX6 ;后者赋予抗生素G418(遗传霉素)抗性。最近已经描述了更多的标记物,但是将它们引入酵母细胞通常需要从头开始施加应变。为了克服这个问题,我们和其他团队已经创建了具有与 + 和 kanMX6 的侧翼同源性的转换盒,这使得能够有效和省时的方式在现有的突变或标记的裂变酵母菌株中交换标记。
 在这里,我们提出了裂殖酵母,粟酒裂殖酵母(Schizosaccharomyces pombe)中醋酸锌转化的单步标记转换方案。以下我们将介绍如何将 ura4 + 标记交换到kanMX6 , natMX4 或 hphMX4标记,其分别对抗生素G418,海参(clonNAT)或潮霉素B提供抗性。我们还详细介绍了如何交换营养标记的任何 MX 标记,例如 arg3 + , his3 + , leu1 + 和 ura4 + 。

背景 这种用于粟酒裂殖酵母的单步骤标记交换方案允许将标记有类型的抗生素标记的任何标记或突变的基因替换为营养标记物(含有arg3 + , + ,并且已经构建了 ura4 + )并且为任何 MX交换遗传 ura4 + ...
