Nonsense mutation (GAG to TAG) in the RanGAP coding sequence. Generated during remobilization of P{EP}RanGAPEP1173.
A 5bp deletion near the N-terminal end of the RanGAP open reading frame leads to a frameshift.
RanGAP327 homozygotes show a significant decrease in the number of central brain neuroblasts at the second instar larval stage.
Both male and female RanGAPEP1173/RanGAP327 show a progressive decrease in the number of central brain neuroblasts from early third instar larval stage into prepupal stage (i.e. at 72h-120h after larval hatching, but not at 48h after larval hatching).
RanGAP327 is rescued by Scer\GAL4da.G32/RanGAPUAS.Tag:TAP
