Project description:The dorsal patterning in Drosophila is controlled by an extracellular gradient of the morphogens Decapentlaplegic/Screw (Dpp/Scrw), which are members of BMP/TGF-β family. Dpp/Scrw signal is transduced to the nucleus by the transcription factors, Mad/Medea. The transcriptional effectors exert their regulation in a graded-manner eliciting at least three threshold responses: high, intermediate and low. However, the mechanism underlying differential response to Dpp is poorly understood, due in part to the insufficient number of well-studied target genes. Gene expression changes were analysed in ectopic overexpressing Dpp mutant embryos to identify new target genes of Dpp/Mad pathway.
