V188M
Site of nucleotide substitution in mutant inferred by FlyBase based on reported amino acid change.
When in trans with Df(2L)TW119 the transgene P{Dipt2.2-lacZ} is not induced.
Strong dorsalization: loss of ventral epidermis.
Weak dorsal phenotype.
dl5 has embryo phenotype, suppressible by Tcas\dlUAS.cCa/Scer\GAL4VP16.mat.αTub67C
Expression of Tcas\dlScer\UAS.cCa under the control of Scer\GAL4mat.alphaTub67C.T:Hsim\VP16 partially suppresses dl5/Df(2L)TW119. One copy of the transgene leads to differentiation of dorsolateral structures (e.g. filzkorper); two copies promote, in addition, the formation of ventrolateral structures (e.g. ventral epidermis).
Df(2L)TW119/dl5 is rescued by dlUAS.cCa/Scer\GAL4VP16.mat.αTub67C
Expression of dlScer\UAS.cCa under the control of Scer\GAL4mat.alphaTub67C.T:Hsim\VP16 completely suppresses the dl5/Df(2L)TW119 phenotype, sometimes even to the point of ventralisation.
