MODIFIED CMV PROMOTERS THAT ARE RESISTANT TO GENE SILENCING

摘要

The invention relates to a nucleic acid molecule comprising a functional promoter of a herpesvirus, a functional enhancer of a herpesvirus, and one or more internal elements of the CpG island of the aprt (adenine phosphoribosyl transferase) gene and/or a functional variant thereof. A method of producing a desired polypeptide using the nucleic acid molecule, a vector and a host cell containing the nucleic acid molecule are also disclosed.
