NmrA-like family domain-containing protein 1

Gene

NMRAL1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Redox sensor protein. Undergoes restructuring and subcellular redistribution in response to changes in intracellular NADPH/NADP+ levels. At low NADPH concentrations the protein is found mainly as a monomer, and binds argininosuccinate synthase (ASS1), the enzyme involved in nitric oxide synthesis. Association with ASS1 impairs its activity and reduces the production of nitric oxide, which subsecuently prevents apoptosis. Under normal NADPH concentrations, the protein is found as a dimer and hides the binding site for ASS1. The homodimer binds one molecule of NADPH. Has higher affinity for NADPH than for NADP+. Binding to NADPH is necessary to form a stable dimer.3 Publications

Miscellaneous

Reduced levels of NMRAL1 by RNAi increases nitric oxide production and reduces cell viability. Overexpression of NMRAL1 increases cell viability.

Caution

Lacks the conserved Tyr residue in the active site triad of Ser-Tyr-Lys necessary for dehydrogenase activity, suggesting that it has no oxidoreductase activity.Curated
