NMRAL1 Lysates

Redox sensor protein. Undergoes restructuring and subcellular redistribution in response to changes inintracellular NADPH/NADP(+) levels. At low NADPH concentrations the protein is found mainly as a monomer, and bindsargininosuccinate synthase (ASS1), the enzyme involved in nitric oxide synthesis. Association with ASS1 impairs itsactivity and reduces the production of nitric oxide, which subsecuently prevents apoptosis. Under normal NADPHconcentrations, the protein is found as a dimer and hides the binding site for ASS1. The homodimer binds one moleculeof NADPH. Has higher affinity for NADPH than for NADP(+). Binding to NADPH is necessary to form a stable dimer
