  sub:_5 prov:value "Phox2b is a vertebrate homeodomain transcription factor and a well established intrinsic factor in developing autonomic ganglia, where its expression is triggered by the bone morphogenic proteins secreted by the dorsal aorta. In this study we characterized its proximal 5'-regulatory region and found that it contained five putative DNA sites that potentially bind homeodomain proteins, including PHOX2B itself. Chromatin immunoprecipitation assays showed that PHOX2B could bind its own promoter in vivo, and electromobility gel shift assays confirmed that four of the five sites could be involved in PHOX2B binding. Functional experiments demonstrated that 65% of the transcriptional activity of the PHOX2B promoter in neuroblastoma cells depends on this auto-regulatory mechanism and that all four sites were required for full self-transactivation." ;
