molecular function
    GO:0044714    2-hydroxy-(deoxy)adenosine-triphosphate pyrophosphatase activity    Catalysis of the reaction: 2-hydroxy-(deoxy)adenosine-triphosphate + H2O = 2-hydroxy-(deoxy)adenosine phosphate + diphosphate.
    GO:0044713    2-hydroxy-adenosine triphosphate pyrophosphatase activity    Catalysis of the reaction: 2-hydroxy-adenosine-triphosphate + H2O = 2-hydroxy-adenosine phosphate + diphosphate.
    GO:0035539    8-oxo-7,8-dihydrodeoxyguanosine triphosphate pyrophosphatase activity    Catalysis of the reaction: 8-oxo-7,8-dihydrodeoxyguanosine-triphosphate + H2O = 8-oxo-7,8-dihydrodeoxyguanosine phosphate + diphosphate. 8-oxo-7,8-dihydrodeoxyguanosine-triphosphate, or 8-oxo-dGTP, is the oxidised form of the free guanine nucleotide and can act as a potent mutagenic substrate for DNA synthesis causing transversion mutations. 8-oxo-dGTPase hydrolyses 8-oxo-dGTP to its monophosphate form to prevent the misincorporation of 8-oxo-dGTP into cellular DNA.
    GO:0008413    8-oxo-7,8-dihydroguanosine triphosphate pyrophosphatase activity    Catalysis of the reaction: 8-oxo-7,8-dihydroguanosine triphosphate = 8-oxo-7,8-dihydroguanosine phosphate + diphosphate. 8-oxo-7,8-dihydroguanosine triphosphate (8-oxo-GTP) is the oxidised form of the free guanine nucleotide and can act as a potent mutagenic substrate for transcription.
    GO:0047693    ATP diphosphatase activity    Catalysis of the reaction: ATP + H2O = AMP + diphosphate.
    GO:0036219    GTP diphosphatase activity    Catalysis of the reaction: GTP + H2O = GMP + diphosphate.
    GO:0003924    GTPase activity    Catalysis of the reaction: GTP + H2O = GDP + phosphate.
    GO:0003723    RNA binding    Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
    GO:0016787    hydrolase activity    Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
    GO:0050072    m7G(5')pppN diphosphatase activity    Catalysis of the reaction: 7-methylguanosine 5'-triphospho-5'-polynucleotide + H2O = 7-methylguanosine 5'-phosphate + polynucleotide.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    GO:0030515    snoRNA binding    Interacting selectively and non-covalently with small nucleolar RNA.
biological process
    GO:0042262    DNA protection    Any process in which DNA is protected from damage by, for example, oxidative stress.
    GO:0006281    DNA repair    The process of restoring DNA after damage. Genomes are subject to damage by chemical and physical agents in the environment (e.g. UV and ionizing radiations, chemical mutagens, fungal and bacterial toxins, etc.) and by free radicals or alkylating agents endogenously generated in metabolism. DNA is also damaged because of errors during its replication. A variety of different DNA repair pathways have been reported that include direct reversal, base excision repair, nucleotide excision repair, photoreactivation, bypass, double-strand break repair pathway, and mismatch repair pathway.
    GO:0046061    dATP catabolic process    The chemical reactions and pathways resulting in the breakdown of dATP, deoxyadenosine triphosphate (2'-deoxyadenosine 5'-triphosphate).
    GO:0006203    dGTP catabolic process    The chemical reactions and pathways resulting in the breakdown of dGTP, guanosine triphosphate.
    GO:0034656    nucleobase-containing small molecule catabolic process    The chemical reactions and pathways resulting in the breakdown of a nucleobase-containing small molecule: a nucleobase, a nucleoside, or a nucleotide.
    GO:0006195    purine nucleotide catabolic process    The chemical reactions and pathways resulting in the breakdown of a purine nucleotide, a compound consisting of nucleoside (a purine base linked to a deoxyribose or ribose sugar) esterified with a phosphate group at either the 3' or 5'-hydroxyl group of the sugar.
    GO:0006979    response to oxidative stress    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of oxidative stress, a state often resulting from exposure to high levels of reactive oxygen species, e.g. superoxide anions, hydrogen peroxide (H2O2), and hydroxyl radicals.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    GO:0070062    extracellular exosome    A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
    GO:0005759    mitochondrial matrix    The gel-like material, with considerable fine structure, that lies in the matrix space, or lumen, of a mitochondrion. It contains the enzymes of the tricarboxylic acid cycle and, in some organisms, the enzymes concerned with fatty acid oxidation.
    GO:0005739    mitochondrion    A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.
    GO:0005634    nucleus    A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
