Expression of Mmus\Ctnna1^{Scer\UAS.P\T.cDa} under the control of Scer\GAL4^da.G32 and Scer\GAL4^Act.PU partially suppresses the follicular epithelium cell phenotypes seen in α-Cat¹ mutant follicle cell clones (generated through recombination of the α-Cat^Ubi.PS rescue construct). The border cell migration defects are not rescued.

Ubiquitous expression of Mmus\Ctnna1^{Scer\UAS.P\T.cDa} under the control of Scer\GAL4^da.G32 and Scer\GAL4^Act.PU fails to rescue the head involution defects seen in α-Cat¹ mutant embryos. Animals are unable to live beyond the embryonic stages.
