The axon death defect (severed axons remain intact for a full week after an axotomy, instead of being cleared away by day 5) characteristic for Ect44314 or Ect4896 mutants is rescued by combination with Ect4+tOa.
Ect4+tOa rescues the lethality and reverts the suppression of axonal degeneration after axon severing which is seen in Ect4896/Df(3L)BSC795 and Ect4896/Ect44621 animals.
