Background: Renalase

Renalase has been reported to regulate cardiac function and blood pressure and initially proposed to metabolize ciculating catecholamines (1). Recent characterization has clarified the true enzymatic function of renalase is oxidation of NAD(P)H isomers to B-NAD(P)+ (2, 3). As these molecules are potent inhibitors of primary metabolism dehydrogenases, cellular renalase activity serves to prevent the inhibitory effects of these molecules on primary metabolism (2, 3). Renalase was initially found to have robust expression in the kidney (1) and later confirmed to have systemic expression in all tissues. Renalase is classified as a member of the flavoprotein superfamily but uniquely lacks an internal structural element that causes its active site to be solvent exposed (4). Renalase contains a putative secretory N-terminal signal sequence (aa 1-17) that also contains residues required for FAD cofactor binding, suggesting that the enzyme would require the N-terminus to remain functionally active (3). However, renalase is found both intracellularly and secreted extracellularly. Extracellular renalase is cleaved during secretion from the cell (5). Circulating renalase acts as a cytokine, resulting in extensive reported physiological effects (6). Increases in blood pressure was induced by renalase gene knockout (7) and gene deletion aggravates acute ischemic kidney (8). Polymorphisms in renalase are associated with hypertension and stroke in type 2 diabetes (9, 10). Full-length recombinant renalase as well as truncated, non-active, peptides were found to promote cell and organ survival in a process independent of enzymatic activity via signaling through the receptor PMCA4b, characterized as an ATPase involved in cell signaling and cardiac hypertrophy (11, 12). Renalase was significantly increased in pancreatic, bladder, breast and melanoma cancers where its signaling role favors cell survival and tumor growth (13). Consequently, renalase inhibition has been suggested to provide a novel therapeutic option for cancer treatment (13).
