Abstract
We constructed cell lines containing various enhancer elements cloned upstream from a marker gene. By microinjection of specific antibodies directed against transcriptional activator proteins into these cell lines, we have developed a functional assay for factors which regulate the activity of target promoters. Here we show that microinjection of a highly specific antibody to the cyclic AMP enhancer element-binding (CREB) protein diminishes gene expression in response to cyclic AMP in living fibroblasts.Entities:
