the present study demonstrates that nNOS-derived NO signaling modulated by spinal Sig-1R activation increases Nox2 activity and concomitant ROS production, which leads to a ROS-induced increase in PKC-dependent pGluN1 expression in the spinal cord dorsal horn and the development of pain hypersensitivity
We conclude that synaptotagmin-1 (show SYT1 Proteins) phosphorylation is an essential step in PKC-dependent potentiation of synaptic transmission, acting downstream of the two other essential DAG/PKC substrates, Munc13-1 and Munc18-1 (show STXBP1 Proteins).

Protein kinase C (PKC) is a family of serine- and threonine-specific protein kinases that can be activated by calcium and the second messenger diacylglycerol. PKC family members phosphorylate a wide variety of protein targets and are known to be involved in diverse cellular signaling pathways. PKC family members also serve as major receptors for phorbol esters, a class of tumor promoters. Each member of the PKC family has a specific expression profile and is believed to play a distinct role in cells. The protein encoded by this gene is one of the PKC family members. This kinase has been reported to play roles in many different cellular processes, such as cell adhesion, cell transformation, cell cycle checkpoint, and cell volume control. Knockout studies in mice suggest that this kinase may be a fundamental regulator of cardiac contractility and Ca(2+) handling in myocytes.
