Fig. 9. Model of Egfr/Ras pathway function in early pupal vein cells.

Fig. 9

Rhomboid expression in presumptive vein cells activates Egfr ligands, leading to signaling through the Egfr/Ras pathway. Ras signaling directs vein cell identity through Dpp, and affects shg expression and protein localization (apical concentration) to alter vein cell shape in a Dpp-independent fashion.
