英文摘要：

Structural and functional characterization functional membrane proteomics, which relies on the of membrane transport protein is very important in isolation and purification of large amount of functional proteins. However, effective overexpression and purification of biologically active membrane transport proteins are the primary bottleneck in contemporary functional and structural proteomics studies. Crucial factors influencing membrane protein overproductions include topological analysis of target proteins and selections of detergents. Topological analysis provides valuable information in constructing recombinant membrane transport proteins for in vivo expression. Detergents, which used to maintain the native structure and function of lipid-free membrane proteins, play important roles in cell-free expression, affinity purification of membrane transport proteins, and in vitro their refolding from inclusion bodies. In this article, we reviewed the key strategies and crucial techniques for the overexpression and purification of membrane transport proteins in functional proteomics.
