When PakAID.Scer\UAS.T:Zzzz\FLAG is driven by Scer\GAL4LE a a high frequency of embryonic lethality is seen, with 44% of embryo failing to form cuticle. Of the embryos that form cuticle 21% demonstrate dorsal closure defects in the form of small holes in the dorsal surface of the embryos. Irregularities are seen in cell shape change in the epidermis. Animals expressing PakAID.Scer\UAS.T:Zzzz\FLAG driven by Scer\GAL4GMR.PF have abnormally thick axon bundles in the medulla neuropil in the developing eye and axons terminate in poorly differentiated growth cones. When PakAID.Scer\UAS.T:Zzzz\FLAG is driven by Scer\GAL4c381 a high frequency of embryonic lethality is seen, with more than half of the embryos failing to secrete cuticle. Of those embryos that do secrete cuticle, about 25% have large holes in the dorsal surface. Mutants also exhibit defects in head involution and incomplete or "puckered" dorsal closure. However cell elongation of the lateral epidermal cells appear normal. When PakAID.Scer\UAS.T:Zzzz\FLAG is driven by Scer\GAL4332.3 a high frequency of embryonic lethality is seen, with more than half of the embryos failing to secrete cuticle. Of those embryos that do secrete cuticle, about 25% have large holes in the dorsal surface. The amnioserosa appears somewhat abnormal, but apical constriction of amnioserosa cells occurs as in wild-type.
PakAID.UAS.Tag:FLAG/Scer\GAL4332.3 is a suppressor | partially of majority die during embryonic stage phenotype of crbGX24w-/crb11A22, crbY10A
PakAID.UAS.Tag:FLAG, Scer\GAL4hs.PB is a non-enhancer of amnioserosa phenotype of Rac1V12.UAS, Scer\GAL4hs.PB
PakAID.UAS.Tag:FLAG/Scer\GAL4332.3 is a suppressor | partially of embryo | dorsal closure stage phenotype of crbGX24w-/crb11A22, crbY10A
PakAID.UAS.Tag:FLAG/Scer\GAL4332.3 is a suppressor | partially of embryonic/first instar larval cuticle | embryonic stage phenotype of crbGX24w-/crb11A22, crbY10A
PakAID.UAS.Tag:FLAG, Scer\GAL4hs.PB is a non-suppressor of amnioserosa phenotype of Rac1V12.UAS, Scer\GAL4hs.PB
Expression of PakAID.Scer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4332.3 partially suppresses the embryonic lethality and dorsal closure defects seen in embryos expressing crbY10A in a crbGX24w-/crb11A22 background, resulting in some adult survival.
