Abstract: Studies of the structure and function of membrane proteins are hotspots of life science in recent years. The most important approach to acquire membrane protein is recombinant expression in prokaryotic system. However, the yield of membrane protein in prokaryotic system is relatively low. Gene sequence optimization is a effective technique to enhance expression of membrane protein in prokaryotic system. In this article, we summarize the latest progress on gene sequence optimization for the prokaryotic expression of membrane proteins, and discuss the factors which affect the expression of membrane protein, including the optimization of rare codons, mRNA stability and translation starting, mRNA and ribosome behaviour, translation rate and membrane protein folding. Our paper provides new possibilities for the over-expression of membrane protein in prokaryotic system.

Key words: membrane protein, over-expression, gene sequence optimization, rare codons optimization, mRNA stability, translation rate, membrane protein folding
