molecular function
    GO:0016492    G-protein coupled neurotensin receptor activity    Combining with the tridecapeptide neurotensin to initiate a G-protein mediated change in cell activity. A G-protein is a signal transduction molecule that alternates between an inactive GDP-bound and an active GTP-bound state.
    GO:0004930    G-protein coupled receptor activity    Combining with an extracellular signal 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.
    GO:0047485    protein N-terminus binding    Interacting selectively and non-covalently with a protein N-terminus, the end of any peptide chain at which the 2-amino (or 2-imino) function of a constituent amino acid is not attached in peptide linkage to another amino-acid residue.
    GO:0046982    protein heterodimerization activity    Interacting selectively and non-covalently with a nonidentical protein to form a heterodimer.
    GO:0042803    protein homodimerization activity    Interacting selectively and non-covalently with an identical protein to form a homodimer.
    GO:0004871    signal transducer activity    Conveys a signal across a cell to trigger a change in cell function or state. A signal is a physical entity or change in state that is used to transfer information in order to trigger a response.
biological process
    GO:0070779    D-aspartate import    The directed movement of D-aspartate, the L-enantiomer of the anion of 2-aminopentanedioic acid, into a cell or organelle.
    GO:0007186    G-protein coupled receptor signaling pathway    A series of molecular signals that proceeds with an activated receptor promoting the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex. The GTP-bound activated alpha-G-protein then dissociates from the beta- and gamma-subunits to further transmit the signal within the cell. The pathway begins with receptor-ligand interaction, or for basal GPCR signaling the pathway begins with the receptor activating its G protein in the absence of an agonist, and ends with regulation of a downstream cellular process, e.g. transcription. The pathway can start from the plasma membrane, Golgi or nuclear membrane (PMID:24568158 and PMID:16902576).
    GO:0008344    adult locomotory behavior    Locomotory behavior in a fully developed and mature organism.
    GO:0050965    detection of temperature stimulus involved in sensory perception of pain    The series of events involved in the perception of pain in which a temperature stimulus is received and converted into a molecular signal.
    GO:0071545    inositol phosphate catabolic process    The chemical reactions and pathways resulting in the breakdown of an inositol phosphate, 1,2,3,4,5,6-cyclohexanehexol, with one or more phosphate groups attached.
    GO:0007612    learning    Any process in an organism in which a relatively long-lasting adaptive behavioral change occurs as the result of experience.
    GO:0043066    negative regulation of apoptotic process    Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process.
    GO:0051280    negative regulation of release of sequestered calcium ion into cytosol    Any process that stops, prevents, or reduces the frequency, rate or extent of the release into the cytosolic compartment of calcium ions sequestered in the endoplasmic reticulum or mitochondria.
    GO:0003085    negative regulation of systemic arterial blood pressure    The process that reduces the force with which blood travels through the systemic arterial circulatory system.
    GO:0007218    neuropeptide signaling pathway    The series of molecular signals generated as a consequence of a peptide neurotransmitter binding to a cell surface receptor.
    GO:0043065    positive regulation of apoptotic process    Any process that activates or increases the frequency, rate or extent of cell death by apoptotic process.
    GO:0090238    positive regulation of arachidonic acid secretion    Any process that increases the rate, frequency, or extent of arachidonic acid secretion, the controlled release of arachidonic acid from a cell or a tissue.
    GO:2001259    positive regulation of cation channel activity    Any process that activates or increases the frequency, rate or extent of cation channel activity.
    GO:0014054    positive regulation of gamma-aminobutyric acid secretion    Any process that activates or increases the frequency, rate or extent of the regulated release of gamma-aminobutyric acid.
    GO:0014049    positive regulation of glutamate secretion    Any process that activates or increases the frequency, rate or extent of the controlled release of glutamate.
    GO:0097151    positive regulation of inhibitory postsynaptic potential    Any process that activates or increases the frequency, rate or extent of inhibitory postsynaptic potential (IPSP). IPSP is a temporary decrease in postsynaptic membrane potential due to the flow of negatively charged ions into the postsynaptic cell. The flow of ions that causes an IPSP is an inhibitory postsynaptic current (IPSC) and makes it more difficult for the neuron to fire an action potential.
    GO:0060732    positive regulation of inositol phosphate biosynthetic process    Any process that increases the rate, frequency or extent of inositol phosphate biosynthesis. Inositol phosphate biosynthetic processes are the chemical reactions and pathways resulting in the formation of an inositol phosphate, 1,2,3,4,5,6-cyclohexanehexol, with one or more phosphate groups attached.
    GO:0051281    positive regulation of release of sequestered calcium ion into cytosol    Any process that activates or increases the frequency, rate or extent of the release into the cytosolic compartment of calcium ions sequestered in the endoplasmic reticulum or mitochondria.
    GO:0098900    regulation of action potential    Any process that modulates the frequency, rate or extent of action potential creation, propagation or termination. This typically occurs via modulation of the activity or expression of voltage-gated ion channels.
    GO:0003254    regulation of membrane depolarization    Any process that modulates the rate, frequency or extent of membrane depolarization. Membrane depolarization is the process in which membrane potential changes in the depolarizing direction from the resting potential, usually from negative to positive.
    GO:0043576    regulation of respiratory gaseous exchange    Any process that modulates the frequency, rate or extent of the process of gaseous exchange between an organism and its environment.
    GO:0051930    regulation of sensory perception of pain    Any process that modulates the frequency, rate or extent of the sensory perception of pain, the series of events required for an organism to receive a painful stimulus, convert it to a molecular signal, and recognize and characterize the signal.
    GO:0033993    response to lipid    Any 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 lipid stimulus.
    GO:0007165    signal transduction    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.
    GO:0001659    temperature homeostasis    A homeostatic process in which an organism modulates its internal body temperature.
cellular component
    GO:0005794    Golgi apparatus    A compound membranous cytoplasmic organelle of eukaryotic cells, consisting of flattened, ribosome-free vesicles arranged in a more or less regular stack. The Golgi apparatus differs from the endoplasmic reticulum in often having slightly thicker membranes, appearing in sections as a characteristic shallow semicircle so that the convex side (cis or entry face) abuts the endoplasmic reticulum, secretory vesicles emerging from the concave side (trans or exit face). In vertebrate cells there is usually one such organelle, while in invertebrates and plants, where they are known usually as dictyosomes, there may be several scattered in the cytoplasm. The Golgi apparatus processes proteins produced on the ribosomes of the rough endoplasmic reticulum; such processing includes modification of the core oligosaccharides of glycoproteins, and the sorting and packaging of proteins for transport to a variety of cellular locations. Three different regions of the Golgi are now recognized both in terms of structure and function: cis, in the vicinity of the cis face, trans, in the vicinity of the trans face, and medial, lying between the cis and trans regions.

    GO:0030425    dendrite    A neuron projection that has a short, tapering, often branched, morphology, receives and integrates signals from other neurons or from sensory stimuli, and conducts a nerve impulse 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.
    GO:0043198    dendritic shaft    Cylindric portion of the dendrite, directly stemming from the perikaryon, and carrying the dendritic spines.
    GO:0043197    dendritic spine    A small, membranous protrusion from a dendrite that forms a postsynaptic compartment - typically receiving input from a single presynapse. They function as partially isolated biochemical and an electrical compartments. Spine morphology is variable including "thin", "stubby", "mushroom", and "branched", with a continuum of intermediate morphologies. They typically terminate in a bulb shape, linked to the dendritic shaft by a restriction. Spine remodeling is though to be involved in synaptic plasticity.
    GO:0005783    endoplasmic reticulum    The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).
    GO:0016021    integral component of membrane    The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

    GO:0005886    plasma membrane    The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
    GO:0032280    symmetric synapse    A synapse that lacks an electron dense postsynaptic specialization. In vertebtrates, these occur primarily on dendrite shafts and neuronal cell bodies and involve persynapses containing clusters of predominantly flattened or elongated vesicles and are typcially inhibitory.
    GO:0045202    synapse    The junction between a nerve fiber of one neuron and another neuron, muscle fiber or glial cell. As the nerve fiber approaches the synapse it enlarges into a specialized structure, the presynaptic nerve ending, which contains mitochondria and synaptic vesicles. At the tip of the nerve ending 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 nerve ending secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane.
    GO:0043195    terminal bouton    Terminal inflated portion of the axon, containing the specialized apparatus necessary to release neurotransmitters. The axon terminus is considered to be the whole region of thickening and the terminal bouton is a specialized region of it.
