| abstract |
The present invention provides a swine beta casein gene, a swine beta casein gene promoter, an expression vector using the promoter, and a method for producing a protein of interest using the expression vector. Since the promoter of the present invention promotes mammary specific expression of the protein of interest, the animal transformed with the promoter of the present invention can secrete a high concentration of the protein of interest in milk, which can be useful for the production of useful proteins.
