6 GO annotations of cellular component
| Name | Definition |
|---|---|
| axon hillock | Portion of the neuronal cell soma from which the axon originates. |
| dendrite | A neuron projection that has a short, tapering, morphology. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body. |
| GABA-ergic synapse | A synapse that uses GABA as a neurotransmitter. These synapses are typically inhibitory. |
| integral component of plasma membrane | The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane. |
| integral component of presynaptic membrane | The component of the presynaptic membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane. |
| neuronal cell body | The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites. |
6 GO annotations of molecular function
| Name | Definition |
|---|---|
| G protein-coupled serotonin receptor activity | Combining with the biogenic amine serotonin and transmitting the signal across the membrane by activating an associated G-protein. Serotonin (5-hydroxytryptamine) is a neurotransmitter and hormone found in vertebrates and invertebrates. |
| G-protein alpha-subunit binding | Binding to a G-protein alpha subunit. The alpha subunit binds a guanine nucleotide. |
| neurotransmitter receptor activity | Combining with a neurotransmitter and transmitting the signal to initiate a change in cell activity. |
| receptor-receptor interaction | The aggregation, arrangement and bonding together of two or more different receptor complexes that individually undergo combination with a hormone, neurotransmitter, drug or intracellular messenger to form a higher level receptor complex. The formation of the higher level complex initiates a change in cell function. |
| serotonin binding | Binding to serotonin (5-hydroxytryptamine), a monoamine neurotransmitter occurring in the peripheral and central nervous systems, also having hormonal properties. |
| signaling receptor binding | Binding to one or more specific sites on a receptor molecule, a macromolecule that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function. |
18 GO annotations of biological process
| Name | Definition |
|---|---|
| adenylate cyclase-inhibiting serotonin receptor signaling pathway | An adenylate cyclase-inhibiting G protein-coupled receptor signaling pathway initiated by serotonin binding to its receptor, and ending with the regulation of a downstream cellular process. |
| behavioral fear response | An acute behavioral change resulting from a perceived external threat. |
| chemical synaptic transmission | The vesicular release of classical neurotransmitter molecules from a presynapse, across a chemical synapse, the subsequent activation of neurotransmitter receptors at the postsynapse of a target cell (neuron, muscle, or secretory cell) and the effects of this activation on the postsynaptic membrane potential and ionic composition of the postsynaptic cytosol. This process encompasses both spontaneous and evoked release of neurotransmitter and all parts of synaptic vesicle exocytosis. Evoked transmission starts with the arrival of an action potential at the presynapse. |
| exploration behavior | The specific behavior of an organism in response to a novel environment or stimulus. |
| G protein-coupled receptor signaling pathway | The series of molecular signals initiated by a ligand binding to its receptor, in which the activated receptor promotes the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex. The GTP-bound activated alpha-G-protein then dissociates from the beta- and gamma-subunits to further transmit the signal within the cell. The pathway begins with receptor-ligand interaction, and ends with regulation of a downstream cellular process. The pathway can start from the plasma membrane, Golgi or nuclear membrane. |
| G protein-coupled receptor signaling pathway, coupled to cyclic nucleotide second messenger | A G protein-coupled receptor signaling pathway in which the signal is transmitted via the activation or inhibition of a nucleotide cyclase activity and a subsequent change in the concentration of a cyclic nucleotide. |
| gamma-aminobutyric acid signaling pathway | The series of molecular signals generated by the binding of gamma-aminobutyric acid (GABA, 4-aminobutyrate), an amino acid which acts as a neurotransmitter in some organisms, to its receptor on the surface of a target cell. |
| negative regulation of gamma-aminobutyric acid secretion | Any process that stops, prevents, or reduces the frequency, rate or extent of the regulated release of gamma-aminobutyric acid. |
| NMDA glutamate receptor clustering | The receptor clustering process in which N-methyl-D-aspartate (NMDA) receptors are localized to distinct domains in the cell membrane. |
| positive regulation of microtubule depolymerization | Any process that activates or increases the frequency, rate or extent of microtubule depolymerization. |
| regulation of dopamine metabolic process | Any process that modulates the frequency, rate or extent of the chemical reactions and pathways involving dopamine. |
| regulation of feeding behavior | Any process that modulates the rate, frequency or extent of the behavior associated with the intake of food. |
| regulation of hormone secretion | Any process that modulates the frequency, rate or extent of the regulated release of a hormone from a cell. |
| regulation of serotonin secretion | Any process that modulates the frequency, rate or extent of the regulated release of serotonin. |
| regulation of synaptic vesicle exocytosis | Any process that modulates the frequency, rate or extent of synaptic vesicle exocytosis. |
| regulation of vasoconstriction | Any process that modulates the frequency, rate or extent of reductions in the diameter of blood vessels. |
| serotonin metabolic process | The chemical reactions and pathways involving serotonin (5-hydroxytryptamine), a monoamine neurotransmitter occurring in the peripheral and central nervous systems, also having hormonal properties. |
| serotonin receptor signaling pathway | The series of molecular signals generated as a consequence of a serotonin receptor binding to one of its physiological ligands. |
