Enables

This protein enables 3 target(s):

TargetCategoryDefinition
GABA-A receptor activitymolecular functionCombining 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 bindingmolecular functionBinding to a protein. [GOC:go_curators]
GABA-gated chloride ion channel activitymolecular functionEnables 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]

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]
postsynaptic membranecellular componentA 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]

Active In

This protein is active in 5 target(s):

TargetCategoryDefinition
neuron projectioncellular componentA prolongation or process extending from a nerve cell, e.g. an axon or dendrite. [GOC:jl, http://www.cogsci.princeton.edu/~wn/]
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]
dendrite membranecellular componentThe portion of the plasma membrane surrounding a dendrite. [GOC:mah]
postsynapsecellular componentThe part of a synapse that is part of the post-synaptic cell. [GOC:dos]
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]

Part Of

This protein is part of 3 target(s):

TargetCategoryDefinition
GABA-A receptor complexcellular componentA protein complex which is capable of GABA-A receptor activity. In human, it is usually composed of either two alpha, two beta and one gamma chain of the GABA-A receptor subunits or 5 chains of the GABA-A receptor subunits rho1-3 (formally known as GABA-C receptor). [GO_REF:0000088, GOC:bhm, GOC:TermGenie, PMID:18790874]
chloride channel complexcellular componentAn ion channel complex through which chloride ions pass. [GOC:mah]
transmembrane transporter complexcellular componentA 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 5 target(s):

TargetCategoryDefinition
gamma-aminobutyric acid signaling pathwaybiological processThe 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]
inhibitory synapse assemblybiological processThe aggregation, arrangement and bonding together of a set of components to form an inhibitory synapse. [GO_REF:0000079, GOC:bf, GOC:PARL, GOC:TermGenie]
chloride transmembrane transportbiological processThe process in which chloride is transported across a membrane. [GOC:TermGenie, GOC:vw]
regulation of postsynaptic membrane potentialbiological processAny process that modulates the potential difference across a post-synaptic membrane. [GOC:dph, GOC:ef]
synaptic transmission, GABAergicbiological processThe vesicular release of gamma-aminobutyric acid (GABA). from a presynapse, across a chemical synapse, the subsequent activation of GABA 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, ISBN:0126603030]
