1 The co-regulator dNAB interacts with Brinker to eliminate cells with reduced Dpp signaling. dipalmitoylphosphatidylserine brinker Drosophila melanogaster
2 Much of the regulation of transcriptional output by Dpp is mediated through repression of the transcriptional repressor Brinker (Brk), and thus through the activation of target genes. dipalmitoylphosphatidylserine brinker Drosophila melanogaster
3 Much of the regulation of transcriptional output by Dpp is mediated through repression of the transcriptional repressor Brinker (Brk), and thus through the activation of target genes. dipalmitoylphosphatidylserine brinker Drosophila melanogaster
4 At the molecular level, reduced Dpp signaling results in Brk upregulation that triggers apoptosis through activation of the JNK pathway. dipalmitoylphosphatidylserine brinker Drosophila melanogaster
5 Here we show that the transcriptional co-regulator dNAB is a Dpp target in the developing wing that interacts with Brk to eliminate cells with reduced Dpp signaling through the JNK pathway. dipalmitoylphosphatidylserine brinker Drosophila melanogaster
6 Here we show that the transcriptional co-regulator dNAB is a Dpp target in the developing wing that interacts with Brk to eliminate cells with reduced Dpp signaling through the JNK pathway. dipalmitoylphosphatidylserine brinker Drosophila melanogaster
7 We further show that both dNAB and Brk are required for cell elimination induced by differential dMyc expression, a process that depends on reduced Dpp transduction in outcompeted cells. dipalmitoylphosphatidylserine brinker Drosophila melanogaster
8 We propose a novel mechanism whereby the morphogen Dpp regulates the responsiveness to its own survival signal by inversely controlling the expression of a repressor, Brk, and its co-repressor, dNAB. dipalmitoylphosphatidylserine brinker Drosophila melanogaster
