"In wild-type embryos 430 min postfertilization, the dense body protein DEB-1/vinculin has already polarized to the basal sarcolemma and is organized into nascent attachments that appear as a continuous stripe of staining along each muscle quadrant (Figure 4E)... DEB-1/vinculin polarizes within the
pat-4 embryos but does not appear to fully assemble into nascent attachments (Figure 4F), as indicated by the different integrin and DEB-1/vinculin localization in
pat-4 mutants (compare arrows in Figures 4D and 4F)."
