      Thoracic muscle abnormalities, easily detach from cuticle and readily dissociate into single fibers: Z discs and myofibrillar attachments are disrupted. Epithelial 'tendon' cells are less affected.

      (Fyrberg et al., 1990)

      Homozygotes are flightless with a normal wing posture.

      (Homyk and Emerson, 1988)

      Actn1/Actn4 jumps and flies abnormally when raised at 22oC but normally when raised at 29oC; temperature-sensitive period for this effect in first half of pupal stage.
