Fig. 8. Time course of the cGMP and myosin responses in wild-type cells. The responses were calculated by first subtracting basal levels of unstimulated cells and are then expressed as a percentage of the maximal response. Data are from Figures 2, 5 and 6; the cGMP occupancy of GbpC is taken from Van Haastert et al. (1982a). Symbols refer to cGMP (open circles); phosphorylation of RLC (filled triangles); phosphorylation of MHC (filled inverted triangles); MHC in the cytoskeleton of wild-type cells (filled squares); and MHC in the cytoskeleton of gca^–/sgc^– and gbpC^–D^– cells (open squares). The cGMP occupancy of GbpC is presented as a dotted line.
