Abstract

G protein-mediated pathways are the most fundamental mechanisms of cell signaling. In order to analyze these pathways, the availability of purified recombinant G proteins are critically important. Using Sf9-Baculovirus expression system, a general and simplified method to purify various G protein subunits is described in this chapter. This method is useful for purification of most of G protein subunits.

摘要

G蛋白介导的信号通路是细胞信号传导最基本的机制。为了分析这些信号通路,获得纯化的重组G蛋白至关重要。本章介绍了一种利用Sf9-杆状病毒表达系统纯化各种G蛋白亚基的通用且简化的方法。该方法对于纯化大多数G蛋白亚基很有用。
