氢-氘交换(HDX)质谱(MS)可以提供关于蛋白质的信息,这些信息可能难以通过其他手段获得。结构/功能的关系,结合相互作用,和修改的影响都已被测量与HDX MS的信号蛋白和多蛋白信号复合物的多样化和不断增长的阵列。由于硬件和软件的改进,现在可以研究参与细胞信号传导的受体和复合物-包括与膜相关的受体和复合物。越来越多的HDX MS研究细胞膜上的信号复合物特别令人兴奋。最近的例子来说明什么可以了解信号蛋白与这种技术。
Hydrogen-deuterium exchange (HDX) mass spectrometry (MS) can provide information about proteins that can be challenging to obtain by other means. Structure/function relationships, binding interactions, and the effects of modification have all been measured with HDX MS for a diverse and growing array of signaling proteins and multiprotein signaling complexes. As a result of hardware and software improvements, receptors and complexes involved in cellular signaling – including those associated with membranes – can now be studied. The growing body of HDX MS studies of signaling complexes at membranes is particularly exciting. Recent examples are presented to illustrate what can be learned about signaling proteins with this technique.
