Chain A (KCNE2_HUMAN | Q9Y6J6)

molecular function
	GO:0005251	delayed rectifier potassium channel activity	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.
	GO:0005242	inward rectifier potassium channel activity	Enables the transmembrane transfer of a potassium ion by an inwardly-rectifying voltage-gated channel. An inwardly rectifying current-voltage relation is one where at any given driving force the inward flow of K+ ions exceeds the outward flow for the opposite driving force. The inward-rectification is due to a voltage-dependent block of the channel pore by a specific ligand or ligands, and as a result the macroscopic conductance depends on the difference between membrane voltage and the K+ equilibrium potential rather than on membrane voltage itself.
	GO:0044325	ion channel binding	Interacting selectively and non-covalently with one or more specific sites on an ion channel, a protein complex that spans a membrane and forms a water-filled channel across the phospholipid bilayer allowing selective ion transport down its electrochemical gradient.
	GO:0005267	potassium channel activity	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.
	GO:0015459	potassium channel regulator activity	Modulates potassium channel activity via direct interaction interaction with a potassium channel (binding or modification).
	GO:0005515	protein binding	Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
	GO:0042803	protein homodimerization activity	Interacting selectively and non-covalently with an identical protein to form a homodimer.
	GO:0005244	voltage-gated ion channel activity	Enables the transmembrane transfer of an ion by a voltage-gated channel. An ion is an atom or group of atoms carrying an electric charge by virtue of having gained or lost one or more electrons. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded.
	GO:0005249	voltage-gated potassium channel activity	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.
	GO:1902282	voltage-gated potassium channel activity involved in ventricular cardiac muscle cell action potential repolarization	Enables the transmembrane transfer of a potassium ion by a voltage-gated channel through the plasma membrane of a ventricular cardiomyocyte contributing to the repolarization phase of an action potential. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded.
biological process
	GO:0007568	aging	A developmental process that is a deterioration and loss of function over time. Aging includes loss of functions such as resistance to disease, homeostasis, and fertility, as well as wear and tear. Aging includes cellular senescence, but is more inclusive. May precede death and may succeed developmental maturation (GO:0021700).
	GO:0061337	cardiac conduction	Transfer of an organized electrical impulse across the heart to coordinate the contraction of cardiac muscles. The process begins with generation of an action potential (in the sinoatrial node (SA) in humans) and ends with a change in the rate, frequency, or extent of the contraction of the heart muscles.
	GO:0086002	cardiac muscle cell action potential involved in contraction	An action potential that occurs in a cardiac muscle cell and is involved in its contraction.
	GO:0035690	cellular response to drug	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 drug stimulus. A drug is a substance used in the diagnosis, treatment or prevention of a disease.
	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:0086009	membrane repolarization	The process in which ions are transported across a membrane such that the membrane potential changes in the repolarizing direction, toward the steady state potential. For example, the repolarization during an action potential is from a positive membrane potential towards a negative resting potential.
	GO:0086011	membrane repolarization during action potential	The process in which ions are transported across a membrane such that the membrane potential changes in the direction from the positive membrane potential at the peak of the action potential towards the negative resting potential.
	GO:0098915	membrane repolarization during ventricular cardiac muscle cell action potential	The process in which ions are transported across a membrane such that the ventricular cardiomyocyte membrane potential changes in the direction from the positive membrane potential at the peak of the action potential towards the negative resting potential.
	GO:1902260	negative regulation of delayed rectifier potassium channel activity	Any process that stops, prevents or reduces the frequency, rate or extent of delayed rectifier potassium channel activity.
	GO:1903817	negative regulation of voltage-gated potassium channel activity	Any process that stops, prevents or reduces the frequency, rate or extent of voltage-gated potassium channel activity.
	GO:1901800	positive regulation of proteasomal protein catabolic process	Any process that activates or increases the frequency, rate or extent of proteasomal protein catabolic process.
	GO:1901387	positive regulation of voltage-gated calcium channel activity	Any process that activates or increases the frequency, rate or extent of voltage-gated calcium channel activity.
	GO:0071435	potassium ion export	The directed movement of potassium ions out of a cell or organelle.
	GO:0010107	potassium ion import	The directed movement of potassium ions into a cell or organelle.
	GO:0071805	potassium ion transmembrane transport	A process in which a potassium ion is transported from one side of a membrane to the other.
	GO:0006813	potassium ion transport	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.
	GO:1902159	regulation of cyclic nucleotide-gated ion channel activity	Any process that modulates the frequency, rate or extent of cyclic nucleotide-gated ion channel activity.
	GO:1902259	regulation of delayed rectifier potassium channel activity	Any process that modulates the frequency, rate or extent of delayed rectifier potassium channel activity.
	GO:0086091	regulation of heart rate by cardiac conduction	A cardiac conduction process that modulates the frequency or rate of heart contraction.
	GO:1901979	regulation of inward rectifier potassium channel activity	Any process that modulates the frequency, rate or extent of inward rectifier potassium channel activity.
	GO:0034765	regulation of ion transmembrane transport	Any process that modulates the frequency, rate or extent of the directed movement of ions from one side of a membrane to the other.
	GO:0060306	regulation of membrane repolarization	Any process that modulates the establishment or extent of a membrane potential in the polarizing direction towards the resting potential, usually from positive to negative.
	GO:1901379	regulation of potassium ion transmembrane transport	Any process that modulates the frequency, rate or extent of potassium ion transmembrane transport.
	GO:0060307	regulation of ventricular cardiac muscle cell membrane repolarization	Any process that modulates the establishment or extent of a membrane potential in the polarizing direction towards the resting potential in a ventricular cardiomyocyte.
	GO:0043586	tongue development	The process whose specific outcome is the progression of the tongue over time, from its formation to the mature structure. The tongue is the movable, muscular organ on the floor of the mouth of most vertebrates, in many other mammals is the principal organ of taste, aids in the prehension of food, in swallowing, and in modifying the voice as in speech.
	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.
	GO:0086005	ventricular cardiac muscle cell action potential	An action potential that occurs in a ventricular cardiac muscle cell.
cellular component
	GO:0009986	cell surface	The external part of the cell wall and/or plasma membrane.
	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:0005764	lysosome	A small lytic vacuole that has cell cycle-independent morphology and is found in most animal cells and that contains a variety of hydrolases, most of which have their maximal activities in the pH range 5-6. The contained enzymes display latency if properly isolated. About 40 different lysosomal hydrolases are known and lysosomes have a great variety of morphologies and functions.
	GO:0016020	membrane	A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
