GO term | GO name | GO namespace | GO def |
GO:0005249 | voltage-gated potassium channel activity | molecular_function | Enables the transmembrane transfer of a potassium ion by a voltage-gated channel. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded. [GOC:mtg_transport, ISBN:0815340729] |
GO:0005267 | potassium channel activity | molecular_function | Enables the facilitated diffusion of a potassium ion (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism. [GOC:BHF, GOC:mtg_transport, GOC:pr, ISBN:0815340729] |
GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
GO:0006813 | potassium ion transport | biological_process | The directed movement of potassium ions (K+) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. [GOC:ai] |
GO:0007268 | chemical synaptic transmission | biological_process | 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. [GOC:jl, MeSH:D009435] |
GO:0051260 | protein homooligomerization | biological_process | The process of creating protein oligomers, compounds composed of a small number, usually between three and ten, of identical component monomers. Oligomers may be formed by the polymerization of a number of monomers or the depolymerization of a large protein polymer. [GOC:ai] |
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:0032590 | dendrite membrane | cellular_component | The portion of the plasma membrane surrounding a dendrite. [GOC:mah] |
GO:0008076 | voltage-gated potassium channel complex | cellular_component | A protein complex that forms a transmembrane channel through which potassium ions may cross a cell membrane in response to changes in membrane potential. [GOC:mah] |
GO:0071805 | potassium ion transmembrane transport | biological_process | A process in which a potassium ion is transported from one side of a membrane to the other. [GOC:mah] |
GO:0045211 | postsynaptic membrane | cellular_component | A specialized area of membrane facing the presynaptic membrane on the tip of the nerve ending and separated from it by a minute cleft (the synaptic cleft). Neurotransmitters cross the synaptic cleft and transmit the signal to the postsynaptic membrane. [ISBN:0198506732] |
GO:0042734 | presynaptic membrane | cellular_component | A specialized area of membrane of the axon terminal that faces the plasma membrane of the neuron or muscle fiber with which the axon terminal establishes a synaptic junction; many synaptic junctions exhibit structural presynaptic characteristics, such as conical, electron-dense internal protrusions, that distinguish it from the remainder of the axon plasma membrane. [GOC:jl, ISBN:0815316194] |
GO:0005251 | delayed rectifier potassium channel activity | molecular_function | Enables the transmembrane transfer of a potassium ion by a delayed rectifying voltage-gated channel. A delayed rectifying current-voltage relation is one where channel activation kinetics are time-dependent, and inactivation is slow. [GOC:mah, PMID:11343411, PMID:2462513] |
GO:0043679 | axon terminus | cellular_component | 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. [GOC:dph, GOC:jl] |
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] |
