FIG. 10.
A schematic diagram illustrating the role of G6PD in regulating CA contractility. A flow diagram illustrates that activation of PKC, most likely PKCδ, by depolarization or G-coupled receptors phosphorylate G6PD, and stimulated G6PD, either directly or via inducing changes in NADPH redox, modulates CA contraction evoked by Ca2+-dependent phosphorylation of MLC.
