  • DNA coding for protein binds to enhancer of .alpha.-fetoprotein gene
    Patent number: 5302698
    Abstract: This invention relates to a DNA coding for a protein that specifically binds to the enhancer of the .alpha.-fetoprotein gene and that promotes transcription of that .alpha.-fetoprotein gene. This DNA is useful, by applying recombinant DNA technology, for the construction of highly efficient gene expression system for the production of proteins having physiological activities in animal cells.
