Detection of Human ADP‑Sugar Pyrophosphatase/NUDT5 by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line, HepG2 human hepatocellular carcinoma cell line, and human liver tissue. PVDF membrane was probed with 0.2 µg/mL of Mouse Anti-Human ADP-Sugar Pyrophosphatase/NUDT5 Monoclonal Antibody (Catalog # MAB6414) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for ADP-Sugar Pyrophosphatase/NUDT5 at approximately 36 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: ADP-Sugar Pyrophosphatase/NUDT5
ADP-Sugar Pyrophosphatase (NUDT5) is a member of the nudix superfamily of enzymes. Members of this family are pyrophosphohydrolases that act upon substrates with the general structure of a nucleoside (Nu) diphosphate (di) linked to another moiety, X (NDP-X) to yield NMP plus P-X (1). Human NUDT5 is a homodimeric enzyme present in the cytosol of most cell types (2). Glu166 and three magnesium ions are important for stabilizing the transition state during the hydrolysis of ADPR (3). NUDT5 has been suggested to play a role in regulating the intracellular levels of ADPR by NO activation through ADP-ribosylation at cysteine residues of the enzyme in macrophages (4). It also may play defensive role against the mutagenesis induced by oxidized deoxyribonucleosides (5, 6).
