Located In

This protein is located in 7 target(s):

TargetCategoryDefinition
nucleoplasmcellular componentThat part of the nuclear content other than the chromosomes or the nucleolus. [GOC:ma, ISBN:0124325653]
cytosolcellular componentThe part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. [GOC:hjd, GOC:jl]
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]
neuronal cell body membranecellular componentThe plasma membrane of a neuron cell body - excludes the plasma membrane of cell projections such as axons and dendrites. [GOC:jl]
presynaptic membranecellular componentA specialized area of membrane of the axon terminal that faces the plasma membrane of the neuron or muscle fiber with which the axon terminal establishes a synaptic junction; many synaptic junctions exhibit structural presynaptic characteristics, such as conical, electron-dense internal protrusions, that distinguish it from the remainder of the axon plasma membrane. [GOC:jl, ISBN:0815316194]
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]
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/]
dendrite membranecellular componentThe portion of the plasma membrane surrounding a dendrite. [GOC:mah]
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]
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]

Involved In

This protein is involved in 12 target(s):

TargetCategoryDefinition
behavioral fear responsebiological processAn acute behavioral change resulting from a perceived external threat. [GOC:dph, PMID:9920659]
signal transductionbiological processThe 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 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]
associative learningbiological processLearning by associating a stimulus (the cause) with a particular outcome (the effect). [ISBN:0582227089]
inner ear receptor cell developmentbiological processThe process whose specific outcome is the progression of an inner ear receptor cell over time, from its formation to the mature structure. Cell development does not include the steps involved in committing a cell to a specific fate. [GOC:dph]
innervationbiological processThe process in which a nerve invades a tissue and makes functional synaptic connection within the tissue. [GOC:dph, GOC:sart]
cochlea developmentbiological processThe progression of the cochlea over time from its formation to the mature structure. The cochlea is the snail-shaped portion of the inner ear that is responsible for the detection of sound. [GOC:dph, GOC:tb]
regulation of presynaptic membrane potentialbiological processAny process that modulates the potential difference across a presynaptic 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]
chloride transmembrane transportbiological processThe process in which chloride is transported across a membrane. [GOC:TermGenie, GOC:vw]
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]
