|KG744||C. elegans||pde-4(ce268) II. Show Description
Hyperactive locomotion and hypersensitive to stimuli such as plate dropping. Restores wild type levels of locomotion to paralyzed ric-8(md303) mutants. Most, but not all adults, appear significantly Egl-c. Some mature adults are thinner than normal. Aldicarb sensitivity, growth rate, pumping, length, and distribution on food are all similar to wild type. The ce268 mutation is a D448N change relative to PDE-4D isoform. It disrupts the catalytic domain by changing one of the four active site residues that together chelate an active site zinc atom. Inheritance is semi-dominant due to dominant negative side effects.
