Translated Gurken is received by Torpedo proteins. Torpedo signal causes follicle cells to differentiate to a dorsal morphology.

Gurken does not diffuse to ventral

follicle cells

GD cleaves Snake to its active form and forms a complex with Snake and uncleaved Easter proteins.

Easter protein is cleaved into its

active form.
