"It has been suggested that, particularly at lower levels of vessel contractility, NO-induced PKG-mediated activation of the BK channel is weaker than NO-induced [Ca ] decrease–mediated deactivation of the BK channel and that the overall decrease in BK channel activity determines the role of BK channels as limiters of the effect of NO."

"Notably, direct application of H 2 O 2 (30 muM) increased Ca 2+ spark frequency in VSMCs from wild-type mice, but did not increase BK channel currents in these same cells treated with ryanodine to block Ca 2+ sparks, further supporting the conclusion that oxidant activated PKG increases BK channel mediated vasodilation of arteries through an increase in Ca 2+ spark frequency rather than a direct effect on the BK channel."

"Mechanistically, PKG has been linked to the activation of the mitochondrial K ATP channel [ xref ] and a recent paper further suggests that PKG activates the cardiomyocyte-specific BK channel at the mitochondria, increasing K + influx into the matrix, opposing mitochondrial Ca 2+ overloading and ROS production [ xref ]."

"The list of PKG targets in smooth muscle cells includes proteins involved in the regulation of the cytoplasmic Ca concentration and the Ca -dependence of smooth muscle contraction.One of the main targets of PKG is the BK channel, which is activated by PKG-dependent phosphorylation [68,69,70]."
