Segment polarity protein which functions in hedgehog (Hh) signaling. Regulates the trafficking and the release of cholesterol-modified hedgehog protein from cells of the posterior compartment (P cells) and is hence required for the effective production of the Hh signal. Ubiquitously expressed throughout the embryo and the imaginal discs. Death during embryogenesis with a strong segment-polarity phenotype. Belongs to the dispatched family.
