WebApr 10, 2024 · Soluble guanylyl cyclase (GC1) and oxido-reductase thioredoxin (Trx1) form a complex that mediates two NO signaling pathways as a function of the redox state of cells. Under physiological conditions, reduced Trx1 (rTrx1) supports the canonical NO-GC1-cGMP pathway by protecting GC1 activity from thiol oxidation. Under oxidative stress, the NO … Guanylate cyclase 2C (GC-C) is an enzyme expressed mainly in intestinal neurons. Activation of GC-C amplifies the excitatory cell response that is modulated by glutamate and acetylcholine receptors. GC-C, while known mainly for its secretory regulation in the intestinal epithelium, is also expressed in the brain.
