Two isoforms of Fs(1)h ChIP-seq. Drosophila melanogaster

ChIP-seq was performed using Drosophila Kc167 cells using antibodies against the two isoforms of Fs(1)h, the Brd4 homologue. Differences in binding patterns between the two isoforms are described. Overall design: We examined the differences in Fs(1)h isoform binding across the genome and describe the short isoform to be correlated with transcription at enhancers and promoters. The long isoform is found predominately at insulator binding sites where multiple insulators are bound.
