Expression system using mammalian beta-actin promoter |
| abstract |
Promoter activities were examined by comparing combinations of promoters and enhancers derived from various genes. A hybrid promoter comprising a combination of a CMV enhancer and a mammalian β-acting promoter, or the post-transcriptional regulatory region of the genomic sequence Woodchuck Hepatitis Virus (WPRE) and a mammalian β-actin promoter was found to be stronger than existing promoters. Furthermore, the activities of the β-acting promoters could be enhanced by coexpressing the oncogene product Ras, which is a transactivator. |
