Functions
14 GO annotations of cellular component
| Name | Definition |
|---|---|
| anchoring junction | A cell junction that mechanically attaches a cell (and its cytoskeleton) to neighboring cells or to the extracellular matrix. |
| asymmetric synapse | A type of synapse occurring between an axon and a dendritic spine or dendritic shaft. Asymmetric synapses, the most abundant synapse type in the central nervous system, involve axons that contain predominantly spherical vesicles and contain a thickened postsynaptic density. Most or all synapses of this type are excitatory. |
| axon terminus | Terminal inflated portion of the axon, containing the specialized apparatus necessary to release neurotransmitters. The axon terminus is considered to be the whole region of thickening and the terminal button is a specialized region of it. |
| basal plasma membrane | The region of the plasma membrane located at the basal end of the cell. Often used in reference to animal polarized epithelial membranes, where the basal membrane is the part attached to the extracellular matrix, or in plant cells, where the basal membrane is defined with respect to the zygotic axis. |
| basolateral plasma membrane | The region of the plasma membrane that includes the basal end and sides of the cell. Often used in reference to animal polarized epithelial membranes, where the basal membrane is the part attached to the extracellular matrix, or in plant cells, where the basal membrane is defined with respect to the zygotic axis. |
| 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. |
| endoplasmic reticulum membrane | The lipid bilayer surrounding the endoplasmic reticulum. |
| glutamatergic synapse | A synapse that uses glutamate as a neurotransmitter. |
| 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 postsynaptic density membrane | The component of the postsynaptic density 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. |
| membrane | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| plasma membrane | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
| synapse | 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. |
6 GO annotations of molecular function
| Name | Definition |
|---|---|
| acetylcholine binding | Binding to acetylcholine, an acetic acid ester of the organic base choline that functions as a neurotransmitter, released at the synapses of parasympathetic nerves and at neuromuscular junctions. |
| G protein-coupled acetylcholine receptor activity | Combining with acetylcholine and transmitting the signal across the membrane by activating an associated G-protein; promotes the exchange of GDP for GTP on the alpha subunit of a heterotrimeric G-protein complex. |
| G protein-coupled acetylcholine receptor binding | Binding to a G protein-coupled acetylcholine receptor. |
| 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. |
| neurotransmitter receptor activity | Combining with a neurotransmitter and transmitting the signal to initiate a change in cell activity. |
| quaternary ammonium group binding | Binding to a quaternary ammonium group, including glycine betaine, choline, carnitine and proline. A quaternary ammonium group is any compound that can be regarded as derived from ammonium hydroxide or an ammonium salt by replacement of all four hydrogen atoms of the NH4+ ion by organic groups. |
16 GO annotations of biological process
| Name | Definition |
|---|---|
| acetylcholine receptor signaling pathway | The series of molecular signals generated as a consequence of an acetylcholine receptor binding to one of its physiological ligands. |
| adenylate cyclase-inhibiting G protein-coupled acetylcholine receptor signaling pathway | An adenylate cyclase-inhibiting G protein-coupled receptor signaling pathway initiated by acetylcholine binding to its receptor, and ending with the regulation of a downstream cellular process. |
| calcium-mediated signaling | Any intracellular signal transduction in which the signal is passed on within the cell via calcium ions. |
| 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. |
| G protein-coupled acetylcholine receptor signaling pathway | 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. |
| 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. |
| negative regulation of heart rate by acetylcholine | The process in which acetylcholine released from vagus nerve endings binds to muscarinic receptors on the pacemaker cells and decreases the rate of heart muscle contraction. |
| positive regulation of smooth muscle contraction | Any process that activates or increases the frequency, rate or extent of smooth muscle contraction. |
| positive regulation of vascular associated smooth muscle contraction | Any process that activates or increases the frequency, rate or extent of vascular smooth muscle contraction. |
| positive regulation of vasoconstriction | Any process that activates or increases the frequency, rate or extent of vasoconstriction. |
| regulation of ion transmembrane transporter activity | Any process that modulates the activity of an ion transporter. |
| regulation of vascular associated smooth muscle contraction | Any process that increases the frequency, rate or extent of vascular smooth muscle contraction. |
| response to acetylcholine | 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 an acetylcholine stimulus. |
| saliva secretion | The regulated release of saliva from the salivary glands. In man, the saliva is a turbid and slightly viscous fluid, generally of an alkaline reaction, and is secreted by the parotid, submaxillary, and sublingual glands. In the mouth the saliva is mixed with the secretion from the buccal glands. In man and many animals, saliva is an important digestive fluid on account of the presence of the peculiar enzyme, ptyalin. |
| smooth muscle contraction | A process in which force is generated within smooth muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. Smooth muscle differs from striated muscle in the much higher actin/myosin ratio, the absence of conspicuous sarcomeres and the ability to contract to a much smaller fraction of its resting length. |
| synaptic transmission, cholinergic | The vesicular release of acetylcholine from a presynapse, across a chemical synapse, the subsequent activation of dopamine 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. |
