Enables

This protein enables 4 target(s):

Target	Category	Definition
channel activity	molecular function	Enables the energy-independent facilitated diffusion, mediated by passage of a solute through a transmembrane aqueous pore or channel. Stereospecificity is not exhibited but this transport may be specific for a particular molecular species or class of molecules. [GOC:mtg_transport, ISBN:0815340729]
acetylcholine binding	molecular function	Binding to acetylcholine, an acetic acid ester of the organic base choline that functions as a neurotransmitter, released at the synapses of parasympathetic nerves and at neuromuscular junctions. [GOC:ai]
heterocyclic compound binding	molecular function	Binding to heterocyclic compound. [GOC:TermGenie]
acetylcholine-gated monoatomic cation-selective channel activity	molecular function	Selectively enables the transmembrane transfer of a cation by a channel that opens upon binding acetylcholine. [GOC:mah, PMID:2466967]

Located In

This protein is located in 5 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]
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]
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]
dopaminergic synapse	cellular component	A synapse that uses dopamine as a neurotransmitter. [GOC:dos]
presynapse	cellular component	The part of a synapse that is part of the presynaptic cell. [GOC:dos]

Active In

This protein is active in 3 target(s):

Target	Category	Definition
neuron projection	cellular component	A prolongation or process extending from a nerve cell, e.g. an axon or dendrite. [GOC:jl, http://www.cogsci.princeton.edu/~wn/]
synapse	cellular component	The 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]
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]

Part Of

This protein is part of 1 target(s):

Target	Category	Definition
acetylcholine-gated channel complex	cellular component	A homo- or hetero-pentameric protein complex that forms a transmembrane channel through which ions may pass in response to acetylcholine binding. [GOC:bf, GOC:mah, PMID:12381728, PMID:15579462]

Involved In

This protein is involved in 8 target(s):

Target	Category	Definition
signal transduction	biological process	The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell. [GOC:go_curators, GOC:mtg_signaling_feb11]
monoatomic ion transmembrane transport	biological process	A 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]
excitatory postsynaptic potential	biological process	A process that leads to a temporary increase in postsynaptic potential due to the flow of positively charged ions into the postsynaptic cell. The flow of ions that causes an EPSP is an excitatory postsynaptic current (EPSC) and makes it easier for the neuron to fire an action potential. [GOC:dph, GOC:ef]
presynaptic modulation of chemical synaptic transmission	biological process	Any process, acting in the presynapse that results in modulation of chemical synaptic transmission. [GOC:dos]
acetylcholine receptor signaling pathway	biological process	The series of molecular signals generated as a consequence of an acetylcholine receptor binding to one of its physiological ligands. [GOC:mah]
synaptic transmission, cholinergic	biological process	The vesicular release of acetylcholine from a presynapse, across a chemical synapse, the subsequent activation of dopamine 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:dos, Wikipedia:Cholinergic]
membrane depolarization	biological process	The process in which membrane potential decreases with respect to its steady-state potential, usually from negative potential to a more positive potential. For example, the initial depolarization during the rising phase of an action potential is in the direction from the negative steady-state resting potential towards the positive membrane potential that will be the peak of the action potential. [GOC:dh, Wikipedia:Depolarization]
response to nicotine	biological process	Any 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 nicotine stimulus. [GOC:bf, GOC:ef, ISBN:0198506732, ISBN:0582227089]
