UASt regulatory sequences drive expression of a mutated form of atl that carries a M383T amino acid substitution; this mutation is equivalent to a M408T change in the orthologous human ATL1 gene, a pathogenic variant associated with SPG3A (an autosomal dominant form of hereditary spastic paraplegia). The coding sequence is tagged with Tag:MYC.
Expression of atlM383T.UAS.Tag:MYC under the control of Scer\GAL4GMR.PU leads to rough eyes when compared to controls.
Expression of atlM383T.UAS.Tag:MYC under the control of Scer\GAL4Toll-6-D42 leads to over-fusion of endoplasmic reticulum (ER) membranes with the resulting formation of large globular ER structures within the cytoplasm of third instar larval brain neurons when compared to controls.
