Two KP elements in tandem, in reverse orientation to the Gpdh gene, the two KP elements being separated by one copy of the 8bp target sequence which occurs at the site of insertion. The insertion site of the tandem KP element is the same as the insertion site of the KP element in GpdhAT198.
The level of Gpdh1 RNA is significantly reduced in the low activity strain Gpdh1AKO107.
Less than 50% activity of glycerol-3-phosphate dehydrogenase compared to normal-activity wild type allele.
Homozygous GpdhAKO107 flies and GpdhAKO107/Df(2L)GpdhA flies have reduced Gpdh enzyme activity compared to wild-type. Slow electrophoretic variant.
Isolated from: Cardwell, Queensland, Australia population, 1988.
