Dorsal dependent CBP binding on a genome wide scale

ABSTRACT: We find a high concordance between the binding of the Drosophila transcription factor Dorsal and the co-activator CBP during early embryogenesis. This relationship was furter examined by comparing CBP distribution in Drosophila embryos derived from wt and mutant flies lacking intranuclear Dorsal (gd7). Our data suggests a specific involvemet of CBP in initiating early dorsoventral patterning, but not in anterioposterior.

CBP and the related p300 protein are widely used transcriptional co-activators in metazoans that interact with multiple transcription factors. Whether CBP/p300 occupies the genome equally with all factors or preferentially binds together with some factors is not known. We therefore compared Drosophila melanogaster CBP (nejire) ChIP-seq peaks with regions bound by 40 different transcription factors in early embryos, and we found high co-occupancy with the Rel-family protein Dorsal. Dorsal is requ  ...[more]
