Fig. 8. Increased levels of secreted Spitz suppress the rough eye phenotype. The rough eye caused by transgenic expression of a truncated Glued product is suppressed by sSpitz overexpression. (A) When the
Gl transgene is driven by two copies of an actin-GAL4 driver, a rough-eye phenotype results. (B) The
Gl phenotype is significantly suppressed by coexpression of the secreted form of Spitz protein from a UAS-sSpitz transgene. Genotypes shown: (A) UASp-
Gl, act5c-GAL4/CyO; act5c-GAL4/+, and (B) UAS-sSpitz/UASp-
Gl, act5c-GAL4; act5c-GAL4/+.
