Enables

This protein enables 5 target(s):

Target	Category	Definition
GABA-A receptor activity	molecular function	Combining with the amino acid gamma-aminobutyric acid (GABA, 4-aminobutyrate) to initiate a change in cell activity. GABA-A receptors function as chloride channels. [PMID:8974333]
protein domain specific binding	molecular function	Binding to a specific domain of a protein. [GOC:go_curators]
GABA-gated chloride ion channel activity	molecular function	Enables the transmembrane transfer of a chloride ion by a channel that opens when GABA has been bound by the channel complex or one of its constituent parts. [GOC:mtg_transport, ISBN:0815340729]
transmitter-gated monoatomic ion channel activity involved in regulation of postsynaptic membrane potential	molecular function	Any transmitter-gated ion channel activity that is involved in regulation of postsynaptic membrane potential. [GO_REF:0000061, GOC:TermGenie, PMID:20200227]
neurotransmitter receptor activity	molecular function	Combining with a neurotransmitter and transmitting the signal to initiate a change in cell activity. [GOC:jl, GOC:signaling]

Located In

This protein is located in 3 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]
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]
GABA-ergic synapse	cellular component	A synapse that uses GABA as a neurotransmitter. These synapses are typically inhibitory. [GOC:dos]

Active In

This protein is active in 3 target(s):

Target	Category	Definition
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]
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/]

Target	Category	Definition
chloride channel complex	cellular component	An ion channel complex through which chloride ions pass. [GOC:mah]
GABA-A receptor complex	cellular component	A protein complex which is capable of GABA-A receptor activity.

transmembrane transporter complex	cellular component	A transmembrane protein complex which enables the transfer of a substance from one side of a membrane to the other. [GOC:bhm, GOC:TermGenie, PMID:18024586]

Involved In

This protein is involved in 7 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]
gamma-aminobutyric acid signaling pathway	biological process	The series of molecular signals generated by the binding of gamma-aminobutyric acid (GABA, 4-aminobutyrate), an amino acid which acts as a neurotransmitter in some organisms, to its receptor on the surface of a target cell. [GOC:mah]
chemical synaptic transmission	biological process	The 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]
visual perception	biological process	The series of events required for an organism to receive a visual stimulus, convert it to a molecular signal, and recognize and characterize the signal. Visual stimuli are detected in the form of photons and are processed to form an image. [GOC:ai]
regulation of postsynaptic membrane potential	biological process	Any process that modulates the potential difference across a post-synaptic membrane. [GOC:dph, GOC:ef]
regulation of membrane potential	biological process	Any process that modulates the establishment or extent of a 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. [GOC:jl, GOC:mtg_cardio, GOC:tb, ISBN:0198506732]
chloride transmembrane transport	biological process	The process in which chloride is transported across a membrane. [GOC:TermGenie, GOC:vw]
