The putative ATPase chromatin-remodeling machine SRCAP was identified in a yeast two-hybrid protein screen by interaction with the histone acetylase CBP. SRCAP is implicated in the transcriptional coactivation of cyclic AMP- and steroid-dependent promoters, but no natural chromosomal targets for SRCAP regulation have been identified. DOM is the unique SRCAP homolog in Drosophila melanogaster. The goal of this study was to test whether SRCAP is a functional homolog of DOM and to identify potential activities and targets of SRCAP in vivo. We show that human SRCAP complements recessive domino mutant phenotypes. This rescue depends on an intact ATPase homology domain. SRCAP colocalizes extensively with DOM on Drosophila polytene chromosomes and is recruited to sites of active transcription, such as steroid-regulated loci, but not to activated heat shock loci. We show that SRCAP recruits Drosophila CBP to ectopic chromosomal sites, providing the first evidence to suggest that SRCAP and CBP interact directly or indirectly on chromosomes. We show that DOM is a Notch pathway activator in Drosophila and that wild-type SRCAP-but not an ATPase domain mutant-can substitute for DOM in Notch-dependent wing development. We show that SRCAP potentiates Notch-dependent gene activation in HeLa cells. Taken together, these data implicate SRCAP and DOM in developmental gene activation.
