| metal ion binding | molecular function | Binding to a metal ion. [GOC:ai] |
| A-type (transient outward) potassium channel activity | molecular function | Enables the transmembrane transfer of a potassium ion by an outwardly-rectifying voltage-gated channel that produces a transient outward current upon a step change in membrane potential. [GOC:mah, PMID:5575340] |

| 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] |

| cellular_component | cellular component | A location, relative to cellular compartments and structures, occupied by a macromolecular machine. There are three types of cellular components described in the gene ontology: (1) the cellular anatomical entity where a gene product carries out a molecular function (e.g., plasma membrane, cytoskeleton) or membrane-enclosed compartments (e.g., mitochondrion); (2) virion components, where viral proteins act, and (3) the stable macromolecular complexes of which gene product are parts (e.g., the clathrin complex).

| dendritic spine | cellular component | A small, membranous protrusion from a dendrite that forms a postsynaptic compartment, typically receiving input from a single presynapse. They function as partially isolated biochemical and an electrical compartments. Spine morphology is variable:they can be thin, stubby, mushroom, or branched, with a continuum of intermediate morphologies. They typically terminate in a bulb shape, linked to the dendritic shaft by a restriction. Spine remodeling is though to be involved in synaptic plasticity. [GOC:nln] |
| neuronal cell body | cellular component | The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites. [GOC:go_curators] |
| 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] |

| 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] |

|---|---|---|
| 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] |
| 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] |
| action potential | biological process | A process in which membrane potential cycles through a depolarizing spike, triggered in response to depolarization above some threshold, followed by repolarization. This cycle is driven by the flow of ions through various voltage gated channels with different thresholds and ion specificities. [GOC:dph, GOC:go_curators, GOC:tb, ISBN:978-0-07-139011-8] |
