Glutamatergic-mediated nitric oxide (NO) production occurs via the N-methyl-D-aspartic acid (NMDA) postsynaptic density protein 95 (PSD95)-neuronal nitric oxide synthase (NOS1) ternary complex. The increased intracellular Ca2+ stimulates the interaction of nNOS and calmodulin (CaM) and the translocaton of nNOS from the plasma membrane to the cytoplasm. The dephosphorylation of nNOS by Calcineurin catalyzes the conversion of arginine to citrulline and nitric oxide (NO), which turns on guanylate cyclase and the various cGMP regulated signaling pathways. |
