摘要

The yeast Saccharomyces cerevisiae has been investigated for expression of mammalian opsin as an alter- native to the currently used expression in COS-1 mammalian cells. The synthetic opsin gene was placed under the control of the inducible promoter GAL1 in the multicopy yeast/ Escherichia coli shuttle vector YEpRF1. Transformation of a GAL~+ S. cerevisiae strain with the vector and growth of galactose-induced cultures to saturation showed the produc- tion of 2.0 + - 0.5 mg of opsin from about 10~10 cells by ELISA.
