NUDT18 antibody recognizes Nudix hydrolase 18, an enzyme that belongs to the Nudix hydrolase superfamily responsible for sanitizing the nucleotide pool by hydrolyzing potentially mutagenic or damaged nucleoside triphosphates. These hydrolases protect cells from incorporating oxidized nucleotides such as 8-oxo-dGTP into DNA, which could otherwise lead to mutations and genomic instability. NUDT18 specifically acts on ADP-ribose derivatives and oxidized nucleotide triphosphates, maintaining genomic integrity under conditions of oxidative stress. The NUDT18 antibody is widely used in studies of DNA repair, oxidative stress response, and metabolic regulation of nucleotide turnover.
NUDT18 is encoded by the NUDT18 gene located on human chromosome 10q24.1. The protein contains the characteristic Nudix box motif (GX5EXEEAXE), which coordinates divalent metal ions and mediates catalysis. NUDT18 hydrolyzes substrates such as ADP-ribose and 8-oxo-dGDP, generating corresponding monophosphates and thereby removing potentially harmful oxidized nucleotide intermediates. It is localized in both cytoplasmic and mitochondrial compartments, indicating a role in protecting nucleic acid integrity in multiple cellular environments.
The NUDT18 antibody is typically used to detect a band near 35 kilodaltons on western blot, corresponding to the predicted molecular weight of the mature enzyme. Immunofluorescence analysis shows cytosolic and perinuclear localization, often associated with mitochondria-rich regions. NUDT18 expression is induced by oxidative agents and during cellular stress, suggesting a compensatory mechanism to prevent mutagenesis. Studies have shown that loss or suppression of NUDT18 increases susceptibility to oxidative DNA damage and enhances mutation frequency, linking it to cancer prevention and mitochondrial homeostasis.
Beyond its antioxidant role, NUDT18 contributes to the regulation of ADP-ribose metabolism, a process associated with signaling pathways involving poly(ADP-ribose) polymerases (PARPs) and sirtuins. By degrading ADP-ribose derivatives, NUDT18 helps reset post-translational modification cycles that regulate DNA repair and apoptosis. Dysregulation of this enzyme has been implicated in metabolic stress responses, neurodegenerative diseases, and tumor biology. NSJ Bioreagents provides a validated NUDT18 antibody optimized for western blot, immunofluorescence, and enzyme localization studies, supporting research into oxidative stress defense, DNA repair regulation, and nucleotide metabolism.
Optimal dilution of the NUDT18 antibody should be determined by the researcher.
E.coli-derived human NUDT18 recombinant protein (Position: M1-R291) was used as the immunogen for the NUDT18 antibody.
After reconstitution, the NUDT18 antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
