Abstract

A search for the genes interacting with the Merlin tumor suppressor gene revealed a Merlin-porcupine interaction during wing morphogenesis. Ectopic expression of the porcupine gene in the wing imaginal disk reduced the adult wing, while addition of an UAS construct with a full-length or truncated copy of the Merlin gene partly restored the wing phenotype. The highest restoration level was observed upon adding the fragments coding for the C end of the Merlin protein. In addition, the porcupine gene was shown to mediate the wingless gene autoregulation, which occurs at two ontogenetic stages, segmentation during embryo development and determination of the wg expression band at the boundary between the dorsal and ventral compartments of the wing imaginal disk.
