    • Improved methods for detecting changes in ion channel activity are described. A membrane with first and second ion channels is provided. The transmembrane potential of the membrane is predominantly set by the first or second ion channel, which are in dominant/recessive relationship and have opposite effects on the transmembrane potential. When the first ion channel is dominant, inhibition of that ion channel allows the second ion channel to predominantly set the transmembrane potential. Because the ion channels have opposite effects on the transmembrane potential, the magnitude of the change in transmembrane potential when the first ion channel is inhibited is greater than the magnitude of the change when the first ion channel is inhibited in the absence of the second ion channel. Such enhanced changes in transmembrane potential are more readily detectable. The methods can be used as screening assays to identify inhibitors of ion channel activity. Corresponding methods allowing identification of activators and enhancers of ion channel activity are also described.
    • 描述了用于检测离子通道活性变化的改进方法。 提供具有第一和第二离子通道的膜。 膜的跨膜电位主要由第一或第二离子通道设定,其处于显性/隐性关系,并且对跨膜电位具有相反的作用。 当第一离子通道占优势时,该离子通道的抑制允许第二离子通道主要设定跨膜电位。 因为离子通道对跨膜电位具有相反的作用,所以当第一离子通道被抑制时,跨膜电位变化的大小大于当不存在第二离子通道时第一离子通道被抑制时的变化幅度 。 跨膜电位的这种增强的变化更易于检测。 该方法可用作筛选测定以鉴定离子通道活性的抑制剂。 还描述了允许鉴定离子通道活性的活化剂和增强剂的相应方法。

    • Methods for screening for modulators of kinase or phosphatase activity are described. The methods comprise: a) providing a serine or threonine kinase and a substrate which can be phosphorylated by the kinase; b) contacting the kinase with its substrate in the presence and absence of a candidate modulator of the activity of the kinase under conditions which permit phosphorylation of the substrate by the kinase; c) contacting the substrates treated according to step (b) with a reporter, excluding a natural antibody, which binds phosphorylated substrate with higher affinity than unphosphorylated substrate; and d) comparing binding of the reporter to the substrate treated according to step (b) in the presence of the candidate modulator with binding of the reporter to the substrate treated according to step (b) in the absence of the candidate modulator. Examples of reporters for use in such assays include 14-3-3 proteins and WW domain containing proteins.
