This protein enables 3 target(s):

Target	Category	Definition
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]
protein binding	molecular function	Binding to a protein. [GOC:go_curators]
protein heterodimerization activity	molecular function	Binding to a nonidentical protein to form a heterodimer. [GOC:ai]

This protein is located in 4 target(s):

Target	Category	Definition
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]
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.

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]
perikaryon	cellular component	The portion of the cell soma (neuronal cell body) that excludes the nucleus. [GOC:jl]

This protein is active in 3 target(s):

Target	Category	Definition
membrane	cellular component	A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. [GOC:dos, GOC:mah, ISBN:0815316194]
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. [GOC:aruk, GOC:bc, GOC:dos, GOC:mah, GOC:nln, ISBN:0198506732]
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]

This protein is part of 1 target(s):

Target	Category	Definition
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]

This protein is involved in 6 target(s):

Target	Category	Definition
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]
regulation of smooth muscle contraction	biological process	Any process that modulates the frequency, rate or extent of smooth muscle contraction. [GOC:go_curators]
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]
protein localization to plasma membrane	biological process	A process in which a protein is transported to, or maintained in, a specific location in the plasma membrane. [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]
