Abstract excerpt
Type II P-type ATPases (PAIIs) constitute a family of conserved proteins that actively generate ionic gradients across membranes. Mutations in genes encoding PAIIs can cause heritable dominant diseases, with suggested etiology of haploinsufficiency. Using a Drosophila melanogaster genetic screen, we identified a dominant mutation altering the PAII member sarcoendoplasmic reticulum Ca(2+) ATPase (SERCA). This...
