Tissue- and stage-specific modulation of Wingless signaling by the segment polarity gene lines.

Abstract excerpt

Wnt signaling controls a variety of developmental programs but the mechanisms by which the same signal leads to distinct outputs remain unclear. To address this question, we identified stage-specific modulators of Wingless (Wg) signaling in the Drosophila embryonic epidermis. We show that lines (lin) is essential for Wg-dependent patterning in dorsal epidermis. lin encodes a novel protein that acts...
