molecular function
    GO:0051287    NAD binding    Interacting selectively and non-covalently with nicotinamide adenine dinucleotide, a coenzyme involved in many redox and biosynthetic reactions; binding may be to either the oxidized form, NAD+, or the reduced form, NADH.
    GO:0004013    adenosylhomocysteinase activity    Catalysis of the reaction: S-adenosyl-L-homocysteine + H2O = adenosine + L-homocysteine.
    GO:0098604    adenosylselenohomocysteinase activity    Catalysis of the reaction: Se-Adenosyl-L-selenohomocysteine + H2O => Adenosine + Selenohomocysteine.
    GO:0030554    adenyl nucleotide binding    Interacting selectively and non-covalently with adenyl nucleotides, any compound consisting of adenosine esterified with (ortho)phosphate.
    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:0042802    identical protein binding    Interacting selectively and non-covalently with an identical protein or proteins.
biological process
    GO:0019510    S-adenosylhomocysteine catabolic process    The chemical reactions and pathways resulting in the breakdown of S-adenosylhomocysteine, forming homocysteine and then methionine.
    GO:0033353    S-adenosylmethionine cycle    A cyclic series of interconversions involving S-adenosylmethionine, S-adenosyl-L-homocysteine, L-cysteine, and L-methionine. Couples utilization of the methyl group of SAM with recycling of the homocysteinyl group and regeneration of methionine.
    GO:0002439    chronic inflammatory response to antigenic stimulus    A chronic inflammatory response to an antigenic stimulus. A chronic inflammatory response persists indefinitely during days, weeks, or months in the life of an individual.
    GO:0042745    circadian sleep/wake cycle    The cycle from wakefulness through an orderly succession of sleep states and stages that occurs on an approximately 24 hour rhythm.
    GO:0071268    homocysteine biosynthetic process    The chemical reactions and pathways resulting in the formation of homocysteine, 2-amino-4-sulfanylbutanoic acid.
    GO:0006730    one-carbon metabolic process    The chemical reactions and pathways involving the transfer of one-carbon units in various oxidation states.
    GO:0001666    response to hypoxia    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 a stimulus indicating lowered oxygen tension. Hypoxia, defined as a decline in O2 levels below normoxic levels of 20.8 - 20.95%, results in metabolic adaptation at both the cellular and organismal level.
    GO:0007584    response to nutrient    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 a nutrient stimulus.
    GO:0001887    selenium compound metabolic process    The chemical reactions and pathways involving compounds that contain selenium, such as selenocysteine.
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:0042470    melanosome    A tissue-specific, membrane-bounded cytoplasmic organelle within which melanin pigments are synthesized and stored. Melanosomes are synthesized in melanocyte cells.
    GO:0043005    neuron projection    A prolongation or process extending from a nerve cell, e.g. an axon or dendrite.
    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.
