abstract：:The dorsal protein (DL) regulates the transcriptional activity of several genes that determine cell fate along the dorsoventral axis of the Drosophila melanogaster embryo. DL is present at high levels in ventral nuclei, where it activates some genes (twi and sna) and represses others (zen, dpp, and tld). DL shows homo...
