molecular function |
| GO:0050661 | | NADP binding | | Interacting selectively and non-covalently with nicotinamide-adenine dinucleotide phosphate, a coenzyme involved in many redox and biosynthetic reactions; binding may be to either the oxidized form, NADP+, or the reduced form, NADPH. |
| GO:0070402 | | NADPH binding | | Interacting selectively and non-covalently with the reduced form, NADPH, of nicotinamide-adenine dinucleotide phosphate, a coenzyme involved in many redox and biosynthetic reactions. |
| GO:0003723 | | RNA binding | | Interacting selectively and non-covalently with an RNA molecule or a portion thereof. |
| GO:0004146 | | dihydrofolate reductase activity | | Catalysis of the reaction: 5,6,7,8-tetrahydrofolate + NADP+ = 7,8-dihydrofolate + NADPH + H+. |
| GO:0008144 | | drug binding | | Interacting selectively and non-covalently with a drug, any naturally occurring or synthetic substance, other than a nutrient, that, when administered or applied to an organism, affects the structure or functioning of the organism; in particular, any such substance used in the diagnosis, prevention, or treatment of disease. |
| GO:0033560 | | folate reductase activity | | Catalysis of the reaction: 7,8-dihydrofolate + NADP+ = folate + NADPH + H+. |
| GO:0005542 | | folic acid binding | | Interacting selectively and non-covalently with folic acid, pteroylglutamic acid. Folic acid is widely distributed as a member of the vitamin B complex and is essential for the synthesis of purine and pyrimidines. |
| GO:0003729 | | mRNA binding | | Interacting selectively and non-covalently with messenger RNA (mRNA), an intermediate molecule between DNA and protein. mRNA includes UTR and coding sequences, but does not contain introns. |
| GO:0051870 | | methotrexate binding | | Interacting selectively and non-covalently with methotrexate, an antineoplastic antimetabolite with immunosuppressant properties. It is an inhibitor of tetrahydrofolate reductase and prevents the formation of tetrahydrofolate, necessary for synthesis of thymidylate, an essential component of DNA. |
| GO:0016491 | | oxidoreductase activity | | Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced. |
biological process |
| GO:0000082 | | G1/S transition of mitotic cell cycle | | The mitotic cell cycle transition by which a cell in G1 commits to S phase. The process begins with the build up of G1 cyclin-dependent kinase (G1 CDK), resulting in the activation of transcription of G1 cyclins. The process ends with the positive feedback of the G1 cyclins on the G1 CDK which commits the cell to S phase, in which DNA replication is initiated. |
| GO:0031103 | | axon regeneration | | The regrowth of axons following their loss or damage. |
| GO:0046452 | | dihydrofolate metabolic process | | The chemical reactions and pathways involving dihydrofolate, the dihydroxylated derivative of folate. |
| GO:0046655 | | folic acid metabolic process | | The chemical reactions and pathways involving folic acid, pteroylglutamic acid. Folic acid is widely distributed as a member of the vitamin B complex and is essential for the synthesis of purine and pyrimidines. |
| GO:0006545 | | glycine biosynthetic process | | The chemical reactions and pathways resulting in the formation of glycine, aminoethanoic acid. |
| GO:0009165 | | nucleotide biosynthetic process | | The chemical reactions and pathways resulting in the formation of nucleotides, any nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the glycose moiety; may be mono-, di- or triphosphate; this definition includes cyclic-nucleotides (nucleoside cyclic phosphates). |
| GO:0006730 | | one-carbon metabolic process | | The chemical reactions and pathways involving the transfer of one-carbon units in various oxidation states. |
| GO:0055114 | | oxidation-reduction process | | A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons. |
| GO:0051000 | | positive regulation of nitric-oxide synthase activity | | Any process that activates or increases the activity of the enzyme nitric-oxide synthase. |
| GO:2000121 | | regulation of removal of superoxide radicals | | Any process that modulates the frequency, rate or extent of removal of superoxide radicals. |
| GO:0000083 | | regulation of transcription involved in G1/S transition of mitotic cell cycle | | Any process that regulates transcription such that the target genes are involved in the transition between G1 and S phase of the mitotic cell cycle. |
| GO:0031427 | | response to methotrexate | | 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 methotrexate stimulus. Methotrexate is 4-amino-10-methylformic acid, a folic acid analogue that is a potent competitive inhibitor of dihydrofolate reductase. |
| GO:0006729 | | tetrahydrobiopterin biosynthetic process | | The chemical reactions and pathways resulting in the formation of tetrahydrobiopterin, the reduced form of biopterin (2-amino-4-hydroxy-6-(1,2-dihydroxypropyl)-pteridine). It functions as a hydroxylation coenzyme, e.g. in the conversion of phenylalanine to tyrosine. |
| GO:0046654 | | tetrahydrofolate biosynthetic process | | The chemical reactions and pathways resulting in the formation of tetrahydrofolate, 5,6,7,8-tetrahydrofolic acid, a folate derivative bearing additional hydrogens on the pterin group. |

cellular component |
| GO:0005575 | | cellular_component | | The part of a cell, extracellular environment or virus in which a gene product is located. A gene product may be located in one or more parts of a cell and its location may be as specific as a particular macromolecular complex, that is, a stable, persistent association of macromolecules that function together. |
| 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:0005654 | | nucleoplasm | | That part of the nuclear content other than the chromosomes or the nucleolus. |
