Abstract excerpt
The potent activity of Wnt/Wingless (Wg) signals necessitates sophisticated mechanisms that spatially and temporally regulate their distribution and range of action. The two main receptor components for Wg - Arrow (Arr) and Frizzled 2 (Fz2) - are transcriptionally downregulated by Wg signaling, thus forming gradients that oppose that of Wg. Here, we analyze the relevance of this transcriptional regulation for the...
