molecular function |
| GO:0044736 | | acid-sensing ion channel activity | | Enables the transmembrane transfer of a sodium ion by a neuronal, voltage-insensitive channel that opens when an extracellular proton has been bound by the channel complex. |

biological process |
| GO:0008306 | | associative learning | | Learning by associating a stimulus (the cause) with a particular outcome (the effect). |
| GO:0070588 | | calcium ion transmembrane transport | | A process in which a calcium ion is transported from one side of a membrane to the other by means of some agent such as a transporter or pore. |
| GO:0006812 | | cation transport | | The directed movement of cations, atoms or small molecules with a net positive charge, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. |
| GO:0071467 | | cellular response to pH | | Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a pH stimulus. pH is a measure of the acidity or basicity of an aqueous solution. |
| GO:0034220 | | ion transmembrane transport | | A process in which an ion is transported from one side of a membrane to the other by means of some agent such as a transporter or pore. |
| GO:0006811 | | ion transport | | The directed movement of charged atoms or small charged molecules into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. |
| GO:0007613 | | memory | | The activities involved in the mental information processing system that receives (registers), modifies, stores, and retrieves informational stimuli. The main stages involved in the formation and retrieval of memory are encoding (processing of received information by acquisition), storage (building a permanent record of received information as a result of consolidation) and retrieval (calling back the stored information and use it in a suitable way to execute a given task). |
| GO:0046929 | | negative regulation of neurotransmitter secretion | | Any process that stops, prevents, or reduces the frequency, rate or extent of the regulated release of a neurotransmitter. |
| GO:0070207 | | protein homotrimerization | | The formation of a protein homotrimer, a macromolecular structure consisting of three noncovalently associated identical subunits. |
| GO:0042391 | | regulation of membrane potential | | Any process that modulates the establishment or extent of a membrane potential, the electric potential existing across any membrane arising from charges in the membrane itself and from the charges present in the media on either side of the membrane. |
| GO:0010447 | | response to acidic pH | | 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 pH stimulus with pH < 7. pH is a measure of the acidity or basicity of an aqueous solution. |
| GO:0050915 | | sensory perception of sour taste | | The series of events required to receive a sour taste stimulus, convert it to a molecular signal, and recognize and characterize the signal. This is a neurological process. |
| GO:0035725 | | sodium ion transmembrane transport | | A process in which a sodium ion is transported from one side of a membrane to the other by means of some agent such as a transporter or pore. |
| GO:0006814 | | sodium ion transport | | The directed movement of sodium ions (Na+) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. |
| GO:0006810 | | transport | | The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein. |
cellular component |
| GO:0016021 | | integral component of membrane | | The component of a 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. |
| GO:0005887 | | 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. |
| GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| GO:0005886 | | plasma membrane | | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
| GO:0045202 | | synapse | | The junction between a nerve fiber of one neuron and another neuron, muscle fiber or glial cell. As the nerve fiber approaches the synapse it enlarges into a specialized structure, the presynaptic nerve ending, which contains mitochondria and synaptic vesicles. At the tip of the nerve ending 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 nerve ending secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane. |
