Despite high levels of homology, transcription coactivators p300 and CREB binding protein (CBP) are both indispensable during embryogenesis. They are largely known to regulate the same genes. To identify genes preferentially regulated by p300 or CBP, we performed an extensive genome-wide survey using the ChIP-seq on cell-cycle synchronized cells. We found(More)
Studies on the molecular mechanisms underlying neuronal differentiation are frequently performed using cell lines established from neuroblastomas. In this study we have used mouse N1E-115 neuroblastoma cells that undergo neuronal differentiation in response to DMSO. During differentiation, cyclin-dependent kinase (cdk) activities decline and phosphorylation(More)
The cellular transcription co-activators p300 and the CREB-binding protein CBP are cellular targets for transformation by the E1A proteins of non-oncogenic adenovirus 5 (Ad5). In this study, we show that the E1A proteins of oncogenic Ad12, like those of Ad5, can also bind to CBP and that this interaction is direct. In addition, we show that the Ad12 E1A(More)
The cdk-inhibitor p21(CIP1/WAF1) inhibits the activities of cyclin-dependent kinases and proliferating cell nuclear antigen, thereby repressing cell-cycle progression and DNA replication. Transforming oncogenes, such as E1A of human adenovirus 5 (Ad5), may interfere with such growth-inhibitory proteins. In this study, we show that in various(More)
