UASt regulatory sequences drive expression of the full length Npc2a cDNA.
Expression of Npc2aScer\UAS.cHa under the control of Scer\GAL4tub or Scer\GAL42-286 rescues the lethality seen in Npc2aunspecified ; Npc2bunspecified double homozygotes, such that 78% of the double mutants survive to adulthood.
