Description

A R192Q amino acid substitution has been introduced into the endogenous atl locus; this mutation is equivalent to a R217Q change in the orthologous human ATL1 gene, a pathogenic variant associated with SPG3A (an autosomal dominant form of hereditary spastic paraplegia) and the change has previously been shown to result in a protein that is completely defective in dimerization, GTPase and fusion activities.

      Statement
      Reference

      atlR192Q homozygous third instar larvae exhibit altered endoplasmic reticulum (ER) shape (in brain neurons and ventral nerve cord) and shorter ER profiles (in brain neurons) when compared to controls. Also the morphology of individual Golgi stacks looks altered, as dilated ER or Golgi cisternae are present, as well as double- or multi-membrane autophagosomes.
