      Detailed Description
      Statement
      Reference

      Flies expressing Hsap\SPASTC448Y.Scer\UAS.M1 under the control of Scer\GAL4elav-C155 have an aberrant posture and hold their wings abnormally apart from their body. The penetrance of this phenotype is 100%.

      The time taken for animals to right themselves is significantly increased compared to wild type in flies expressing Hsap\SPASTC448Y.Scer\UAS.M1 under the control of Scer\GAL4elav-C155. The flies also show significantly reduced climbing ability.
