The Drosophila broad-complex regulates developmental changes in transcription and chromatin structure of the 67B heat-shock gene cluster.

Abstract excerpt

At the end of the third larval instar of Drosophila, ecdysone triggers the tissue-specific activation of gene expression. In cytogenetic and molecular studies, the Broad-complex (BR-C) locus has been defined as a key element in the hierarchy of hormonal regulation of gene activity. Here we show that BR-C function is required for the regulation of the small hsp genes, which are clustered in the 67B puff and are...
