Abstract excerpt
We have used a homologous transfection system employing cell lines derived from Xenopus hepatocytes and fibroblasts and cloned Xenopus estrogen receptor to identify a DNA sequence essential for efficient transcription of the powerful estrogen-regulated Xenopus laevis vitellogenin B1 promoter. Although deletion of the CAAT box, the conserved nematode box, and several other sequences had little effect on...
