Overexpression of bazScer\UAS.cPa in amnioserosa under the control of Scer\GAL4332.3 results in a significant increase in duration times for actomyosin assembly-disassembly cycles compared with wild-type. Lull times between pulses are decreased in the transgenic animals compared with wild-type. As a result of the above changes, overexpression of bazScer\UAS.cPa has no statistically significant effect on pulse frequency versus controls.
