Enables

This protein enables 6 target(s):

TargetCategoryDefinition
monoatomic ion channel activitymolecular functionEnables the facilitated diffusion of a monoatomic ion (by an energy-independent process) by passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism. May be either selective (it enables passage of a specific ion only) or non-selective (it enables passage of two or more ions of same charge but different size). [GOC:cy, GOC:mtg_transport, GOC:pr, ISBN:0815340729]
open rectifier potassium channel activitymolecular functionEnables the transmembrane transfer of a potassium ion by an open rectifier voltage-gated channel. An open rectifier current-voltage relationship is one in which the direction of rectification depends on the external potassium ion concentration. [GOC:mah, PMID:8917578]
potassium channel activitymolecular functionEnables 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]
potassium ion leak channel activitymolecular functionEnables the transport of a potassium ion across a membrane via a narrow pore channel that is open even in an unstimulated or 'resting' state. [GOC:mtg_transport, ISBN:0815340729]
S100 protein bindingmolecular functionBinding to a S100 protein. S100 is a small calcium and zinc binding protein produced in astrocytes that is implicated in Alzheimer's disease, Down Syndrome and ALS. [GOC:jid]
outward rectifier potassium channel activitymolecular functionEnables the transmembrane transfer of a potassium ion by an outwardly-rectifying voltage-gated channel. An outwardly rectifying current-voltage relation is one where at any given driving force the outward flow of K+ ions exceeds the inward flow for the opposite driving force. [GOC:mah]

Located In

This protein is located in 2 target(s):

TargetCategoryDefinition
plasma membranecellular componentThe membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. [ISBN:0716731363]
synapsecellular componentThe 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. [GOC:aruk, ISBN:0198506732, PMID:24619342, PMID:29383328, PMID:31998110]

Involved In

This protein is involved in 11 target(s):

TargetCategoryDefinition
potassium ion transportbiological processThe 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]
chemical synaptic transmissionbiological processThe 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]
response to xenobiotic stimulusbiological processAny 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 stimulus from a xenobiotic, a compound foreign to the organim exposed to it. It may be synthesized by another organism (like ampicilin) or it can be a synthetic chemical. [GOC:jl, GOC:krc]
monoatomic ion transmembrane transportbiological processA process in which a monoatomic ion is transported across a membrane. Monatomic ions (also called simple ions) are ions consisting of exactly one atom. [GOC:mah]
negative regulation of cytosolic calcium ion concentrationbiological processAny process that decreases the concentration of calcium ions in the cytosol. [GOC:ai]
regulation of resting membrane potentialbiological processAny process that modulates the establishment or extent of a resting potential, the electrical charge across the plasma membrane, with the interior of the cell negative with respect to the exterior. The resting potential is the membrane potential of a cell that is not stimulated to be depolarized or hyperpolarized. [GOC:dph, GOC:ef, ISBN:0195088433]
cellular response to zinc ionbiological processAny 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 zinc ion stimulus. [GOC:mah]
cellular response to hypoxiabiological processAny 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 stimulus indicating lowered oxygen tension. Hypoxia, defined as a decline in O2 levels below normoxic levels of 20.8 - 20.95%, results in metabolic adaptation at both the cellular and organismal level. [GOC:mah]
cochlea developmentbiological processThe progression of the cochlea over time from its formation to the mature structure. The cochlea is the snail-shaped portion of the inner ear that is responsible for the detection of sound. [GOC:dph, GOC:tb]
potassium ion transmembrane transportbiological processA process in which a potassium ion is transported from one side of a membrane to the other. [GOC:mah]
stabilization of membrane potentialbiological processThe accomplishment of a non-fluctuating 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.
