A System of Repressor Gradients Spatially Organizes the Boundaries of Bicoid-Dependent Target Genes

A System of Repressor Gradients Spatially Organizes the Boundaries of Bicoid-Dependent Target Genes: Hongtao Chen, Zhe Xu, Constance Mei, Danyang Yu, Stephen Small. The homeodomain (HD) protein Bicoid (Bcd) is thought to function as a gradient morphogen that positions boundaries of target genes via threshold-dependent activation mechanisms. Here, we analyze 6....
