| GO:0003924 | GTPase activity | molecular_function | Catalysis of the reaction |
| GO:0005096 | GTPase activator activity | molecular_function | Binds to and increases the activity of a GTPase, an enzyme that catalyzes the hydrolysis of GTP. [GOC:mah] |
| GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
| GO:0007186 | G protein-coupled receptor signaling pathway | biological_process | 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.

| GO:0007213 | G protein-coupled acetylcholine receptor signaling pathway | biological_process | A G protein-coupled receptor signaling pathway initiated by a ligand binding to an acetylcholine receptor on the surface of a target cell, and ends with regulation of a downstream cellular process, e.g. transcription.

| GO:0009968 | negative regulation of signal transduction | biological_process | Any process that stops, prevents, or reduces the frequency, rate or extent of signal transduction. [GOC:sm] |
| GO:0043547 | positive regulation of GTPase activity | biological_process | Any process that activates or increases the activity of a GTPase. [GOC:jl, GOC:mah] |
| GO:0060159 | regulation of dopamine receptor signaling pathway | biological_process | Any process that modulates the frequency, rate or extent of a dopamine receptor signaling pathway activity. A dopamine receptor signaling pathway is the series of molecular signals generated as a consequence of a dopamine receptor binding to one of its physiological ligands. [GOC:dph] |
| GO:0005634 | nucleus | cellular_component | 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. [GOC:go_curators] |
| GO:0005886 | plasma membrane | cellular_component | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. [ISBN:0716731363] |
| GO:0009898 | cytoplasmic side of plasma membrane | cellular_component | The leaflet the plasma membrane that faces the cytoplasm and any proteins embedded or anchored in it or attached to its surface. [GOC:dos, GOC:tb] |
| GO:0030425 | dendrite | cellular_component | 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.

| GO:0032809 | neuronal cell body membrane | cellular_component | The plasma membrane of a neuron cell body - excludes the plasma membrane of cell projections such as axons and dendrites. [GOC:jl] |
| GO:0043204 | perikaryon | cellular_component | The portion of the cell soma (neuronal cell body) that excludes the nucleus. [GOC:jl] |
| GO:0045202 | synapse | cellular_component | The junction between an axon of one neuron and a dendrite of another neuron, a muscle fiber or a glial cell. As the axon approaches the synapse it enlarges into a specialized structure, the presynaptic terminal bouton, which contains mitochondria and synaptic vesicles. At the tip of the terminal bouton is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic terminal bouton secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane. [GOC:aruk, ISBN:0198506732, PMID:24619342, PMID:29383328, PMID:31998110] |
