| molecular function |
|---|
| | GO:0004115 | | 3',5'-cyclic-AMP phosphodiesterase activity | | Catalysis of the reaction: adenosine 3',5'-cyclic phosphate + H2O = adenosine 5'-phosphate. |
| | GO:0047555 | | 3',5'-cyclic-GMP phosphodiesterase activity | | Catalysis of the reaction: guanosine 3',5'-cyclic phosphate + H2O = guanosine 5'-phosphate. |
| | GO:0004114 | | 3',5'-cyclic-nucleotide phosphodiesterase activity | | Catalysis of the reaction: nucleoside 3',5'-cyclic phosphate + H2O = nucleoside 5'-phosphate. |
| | GO:0030552 | | cAMP binding | | Interacting selectively and non-covalently with cAMP, the nucleotide cyclic AMP (adenosine 3',5'-cyclophosphate). |
| | GO:0030553 | | cGMP binding | | Interacting selectively and non-covalently with cGMP, the nucleotide cyclic GMP (guanosine 3',5'-cyclophosphate). |
| | GO:0004118 | | cGMP-stimulated cyclic-nucleotide phosphodiesterase activity | | Catalysis of the reaction: nucleoside 3',5'-cyclic phosphate + H2O = nucleoside 5'-phosphate; catalytic activity is increased in the presence of cGMP. |
| | GO:0003824 | | catalytic activity | | Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic. |
| | GO:0004112 | | cyclic-nucleotide phosphodiesterase activity | | Catalysis of the reaction: a nucleoside cyclic phosphate + H2O = a nucleoside phosphate. |
| | 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: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:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| | GO:0000166 | | nucleotide binding | | Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose. |
| | GO:0008081 | | phosphoric diester hydrolase activity | | Catalysis of the hydrolysis of a phosphodiester to give a phosphomonoester and a free hydroxyl group. |
| biological process |
|---|
| | GO:0006198 | | cAMP catabolic process | | The chemical reactions and pathways resulting in the breakdown of the nucleotide cAMP (cyclic AMP, adenosine 3',5'-cyclophosphate). |
| | GO:0046069 | | cGMP catabolic process | | The chemical reactions and pathways resulting in the breakdown of cyclic GMP, guanosine 3',5'-phosphate. |
| | GO:0008152 | | metabolic process | | The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation. |
| | GO:0043949 | | regulation of cAMP-mediated signaling | | Any process which modulates the frequency, rate or extent of cAMP-mediated signaling, a series of molecular signals in which a cell uses cyclic AMP to convert an extracellular signal into a response. |
| | GO:0010738 | | regulation of protein kinase A signaling | | Any process that modulates the rate, frequency, or extent of protein kinase A signaling. PKA signaling is the series of reactions, mediated by the intracellular serine/threonine kinase protein kinase A, which occurs as a result of a single trigger reaction or compound. |
| | GO:0007165 | | signal transduction | | The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell. |
| 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:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| | GO:0043025 | | neuronal cell body | | The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites. |
| | GO:0043204 | | perikaryon | | The portion of the cell soma (neuronal cell body) that excludes the nucleus. |
