PROCESS FOR PRODUCING PROTEIN IN CELL-FREE PROTEIN SYNTHESIS SYSTEM USING THIOREDOXIN FUSED PROTEIN EXPRESSION VECTOR

摘要

A fusion protein of thioredoxin with a target protein is expressed in a cell-free protein synthesis system to thereby synthesize at least a part of the fusion protein as a soluble protein. It is preferable that the target protein is a highly hydrophobic protein such as a membrane protein. In particular, a membrane protein such a G protein-coupled receptor can be produced in a state being highly soluble and capable of forming a biologically active three dimensional structure. Also, provided a recombinant vector for producing such a membrane protein in a cell-free protein synthesis system.
