Polyclonal Antibody for studying NNMT. Validated for Western Blotting. Highly specific and rigorously validated in-house, NNMT Antibody (CST #24912) is ready to ship. Product Usage Information Western Blotting: 1:1000 Storage Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at -20°C. Do not aliquot the antibody. Protocol Available protocols: Western Blotting Specificity / Sensitivity NNMT Antibody recognizes endogenous levels of total NNMT protein. Species Reactivity: Human Source / Purification Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Leu12 of human NNMT protein. Antibodies are purified by protein A and peptide affinity chromatography. Background Nicotinamide N-methyltransferase (NNMT) is a metabolic enzyme expressed primarily in liver and adipose tissue. It catalyzes the transfer of a methyl group from S-Adenosyl-methionine (SAM) to nicotinamide, yielding 1-methylnicotinamide (MNAM) and S-Adenosyl-L-homocysteine (SAH) (1). This N-methylation enzymatic activity plays an important role in the biotransformation of drugs and xenobiotics, and also contributes to the metabolism of vitamin B3 (2). Knockdown of NNMT was shown to increase both SAM and NAD levels in white adipose tissue of high-fat diet-fed mice, resulting in increased energy expenditure and protection against diet-induced obesity (3). In contrast, increased liver NNMT expression in humans and mice correlated with an improved metabolic profile, through MNAM-mediated SIRT1 protein stabilization (4). In cancer cells, overexpression of NNMT resulted in excess consumption of methyl units from SAM, leading to histone hypomethylation that substantially altered the epigenetic landscape (5). These and other research studies have suggested that NNMT expression may have utility as a diagnostic and prognostic biomarker in cancer (6-8).
