Disclosed are a novel expression vector for efficient expression of recombinant proteins in mammalian cells, a mammalian cell transformed with the vector, and a method for production of the mammalian cell. The expression vector includes a gene expression regulatory site, and a gene encoding the protein downstream thereof, and an internal ribosome entry site further downstream thereof, and a gene encoding a glutamine synthetase further downstream thereof. |
