Located In

This protein is located in 7 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]
axoncellular componentThe long process of a neuron that conducts nerve impulses, usually away from the cell body to the terminals and varicosities, which are sites of storage and release of neurotransmitter. [GOC:nln, ISBN:0198506732]
synaptic vesicle membranecellular componentThe lipid bilayer surrounding a synaptic vesicle. [GOC:mah]
neuronal cell bodycellular componentThe portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites. [GOC:go_curators]
inhibitory synapsecellular componentA synapse in which an action potential in the presynaptic cell reduces the probability of an action potential occurring in the postsynaptic cell. [GOC:dph, GOC:ef]
GABA-ergic synapsecellular componentA synapse that uses GABA as a neurotransmitter. These synapses are typically inhibitory. [GOC:dos]
postsynaptic specialization membranecellular componentThe membrane component of the postsynaptic specialization. This is the region of the postsynaptic membrane in which the population of neurotransmitter receptors involved in synaptic transmission are concentrated. [GOC:dos]

Active In

This protein is active in 5 target(s):

TargetCategoryDefinition
postsynapsecellular componentThe part of a synapse that is part of the post-synaptic cell. [GOC:dos]
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]
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/]
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]
dendrite membranecellular componentThe portion of the plasma membrane surrounding a dendrite. [GOC:mah]

This protein is involved in 6 target(s):

TargetCategoryDefinition

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]
