FIGURE 1.

Dstac and Dmca1D are expressed in stripes that are coextensive with T tubules in larval body wall muscles. (A) Anti-Dstac/phalloidin double labeling showed that Dstac is expressed in stripes centered on the actin network and Z line of larval muscles. The stripe pattern of the labeling along a muscle by anti-Dstac and phalloidin is quantified to show the extent of overlap of the labeling (right). (B) Anti-Dmca1D/phalloidin double labeling showed that Dmca1D is expressed in stripes centered on the actin network and Z line of larval muscles. The stripe pattern of the labeling along a muscle by anti-Dmca1D and phalloidin is quantified to show the overlap of the labeling (right). (C) Anti-Dmca1D labeling in Mef2:GAL4 > UAS:mCD4-tdTomato larvae showed that Dmca1D is found in the T tubules of larval muscles. The stripe pattern of Dmca1D and CD4-tdTomato along the muscle is quantified to show the overlap of the labeling with the T tubules (right). All images are a single plane. Scale bar, 3 μm.
