5kb of unknown DNA inserted within a HindIII fragment within the fifth intron; position of restriction fragment on reference sequence inferred by FlyBase curator
Polytene chromosomes normal.
Acelm38/Ace1 flies rescued by Ace+mFa occasionally show a bang-sensitive phenotype; flies subjected to mechanical shock sometimes produce a burst of uncoordinated motor activity followed by paralysis, from which they recover in approximately 30 seconds. Ace1/Acelm38 flies carrying two copies of AceTM.T:Hsim\gC are viable, although adults are often bang-sensitive.
Schalet, Kernaghan and Chovnick, 1964.
Induced with: ry26.
FlyBase curator comment: FBrf0050439 states that Ace1 is caused by the insertion of unknown DNA into the fifth intron at coordinate +30, however, FBrf0046381 shows that this insertion of DNA is separable from the Ace1 mutation by recombination.
The Ace1 chromosome contains an insertion of approximately 5kb that is not present in Canton-S or Oregon-R flies. The parental chromosome for Ace1 was never isolated and recombination analysis shows that the 5kb insertion is separable from the Ace1 mutation by recombination.
