Enables

This protein enables 1 target(s):

TargetCategoryDefinition
G protein-coupled adenosine receptor activitymolecular functionCombining with adenosine and transmitting the signal across the membrane by activating an associated G-protein; promotes the exchange of GDP for GTP on the alpha subunit of a heterotrimeric G-protein complex. [GOC:bf, GOC:mah, PMID:9755289]

Located In

This protein is located in 3 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]
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]
Schaffer collateral - CA1 synapsecellular componentA synapse between the Schaffer collateral axon of a CA3 pyramidal cell and a CA1 pyramidal cell. [PMID:16399689]

Active In

This protein is active in 3 target(s):

TargetCategoryDefinition
dendritecellular componentA neuron projection that has a short, tapering, morphology. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body. [GOC:aruk, GOC:bc, GOC:dos, GOC:mah, GOC:nln, ISBN:0198506732]
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]
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]

Involved In

This protein is involved in 11 target(s):

TargetCategoryDefinition
inflammatory responsebiological processThe immediate defensive reaction (by vertebrate tissue) to infection or injury caused by chemical or physical agents. The process is characterized by local vasodilation, extravasation of plasma into intercellular spaces and accumulation of white blood cells and macrophages. [GO_REF:0000022, ISBN:0198506732]
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]
activation of adenylate cyclase activitybiological processAny process that initiates the activity of the inactive enzyme adenylate cyclase. [GOC:ai]
regulation of heart contractionbiological processAny process that modulates the frequency, rate or extent of heart contraction. Heart contraction is the process in which the heart decreases in volume in a characteristic way to propel blood through the body. [GOC:dph, GOC:go_curators, GOC:tb]
negative regulation of cell population proliferationbiological processAny process that stops, prevents or reduces the rate or extent of cell proliferation. [GOC:go_curators]
response to woundingbiological processAny 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 stimulus indicating damage to the organism. [GOC:go_curators]
regulation of norepinephrine secretionbiological processAny process that modulates the frequency, rate or extent of the regulated release of norepinephrine. [GOC:ef]
negative regulation of cell migrationbiological processAny process that stops, prevents, or reduces the frequency, rate or extent of cell migration. [GOC:go_curators]
negative regulation of NF-kappaB transcription factor activitybiological processAny process that stops, prevents, or reduces the frequency, rate or extent of the activity of the transcription factor NF-kappaB. [GOC:dph, GOC:rl, GOC:tb]
presynaptic modulation of chemical synaptic transmissionbiological processAny process, acting in the presynapse that results in modulation of chemical synaptic transmission. [GOC:dos]
G protein-coupled adenosine receptor signaling pathwaybiological processThe series of molecular signals generated as a consequence of a receptor binding to extracellular adenosine and transmitting the signal to a heterotrimeric G-protein complex to initiate a change in cell activity. [GOC:dph]
