Abstract excerpt
We examine how the stretch activation response of the Drosophila indirect flight muscles (IFM) is affected by the projectin mutation bentDominant. IFM from flies heterozygous for this mutation (bentD/+) produce approximately 85% full length projectin and approximately 15% truncated projectin lacking the kinase domain and more C-terminal sequences. Passive stiffness and power output of mutant fibers is similar to...
