Detailed Description
Statement
Reference

AtpαDTS2/+ flies are sluggish compared to wild-type. After exposure to 37-38oC, these mutants become paralyzed within 10-30 seconds with complete penetrance. If this restrictive temperature is maintained for 3 minutes, then flies regain the ability to stand after 1-2 minutes at the permissive temperature and can only walk after another few minutes. Wild-type flies never become paralyzed from exposure to 37-38oC. Although AtpαDTS2/+ flies do not show paralysis in response to mechanical shock when maintained and tested at 20-22oC, bang-sensitive paralysis does occur when flies are tested at this temperature if they have been maintained at 28oC. This phenomenon can occur for several hours after placing in the permissive temperature and paralysis lasts around 5-30 seconds. AtpαDTS2 flies have significantly shorter lifespans than wild type and become quite sedentary as they age, with a premature loss of both walking and flight activity. In the brains of middle-aged AtpαDTS2/+ flies, neurodegeneration is evident as the appearance of vacuolar structures throughout the central brain and optic regions. Such structures are rarely seen in wild-type flies. The phenotype is age dependent as young adults (day 2-3 after eclosion) show little neuropathology. This age-dependent neurodegeneration can also be seen in the thoracic ganglion.

Reference

The following double mutants all have a short lifespan of <1 week: parats115; AtpαDTS2, parats1; AtpαDTS2 and paraST109; AtpαDTS2. In contrast, heterozygosity for either paralk5 or Df(1)D34 does not shorten the AtpαDTS1 life span.
