Located In

This protein is located in 5 target(s):

TargetCategoryDefinition
endoplasmic reticulum membranecellular componentThe lipid bilayer surrounding the endoplasmic reticulum. [GOC:mah]
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]
basal plasma membranecellular componentThe region of the plasma membrane located at the basal end of the cell. Often used in reference to animal polarized epithelial membranes, where the basal membrane is the part attached to the extracellular matrix, or in plant cells, where the basal membrane is defined with respect to the zygotic axis. [GOC:go_curators]
basolateral plasma membranecellular componentThe region of the plasma membrane that includes the basal end and sides of the cell. Often used in reference to animal polarized epithelial membranes, where the basal membrane is the part attached to the extracellular matrix, or in plant cells, where the basal membrane is defined with respect to the zygotic axis. [GOC:go_curators]
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 3 target(s):

TargetCategoryDefinition
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]
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]

Involved In

This protein is involved in 19 target(s):

TargetCategoryDefinition
smooth muscle contractionbiological processA process in which force is generated within smooth muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. Smooth muscle differs from striated muscle in the much higher actin/myosin ratio, the absence of conspicuous sarcomeres and the ability to contract to a much smaller fraction of its resting length. [GOC:ef, GOC:jl, GOC:mtg_muscle, 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]
G protein-coupled receptor signaling pathwaybiological processThe series of molecular signals initiated by a ligand binding to its receptor, in which the activated receptor promotes 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, and ends with regulation of a downstream cellular process. The pathway can start from the plasma membrane, Golgi or nuclear membrane. [GOC:bf, GOC:mah, PMID:16902576, PMID:24568158, Wikipedia:G_protein-coupled_receptor]
phospholipase C-activating G protein-coupled acetylcholine receptor signaling pathwaybiological processA phospholipase C-activating G protein-coupled receptor signaling pathway initiated by acetylcholine binding to its receptor on the surface of a target cell, and ending with the regulation of a downstream cellular process, e.g. transcription. [GOC:dph, GOC:mah, GOC:signaling, GOC:tb]
G protein-coupled acetylcholine receptor signaling pathwaybiological processA G protein-coupled receptor signaling pathway initiated by a ligand binding to an acetylcholine receptor on the surface of a target cell, and ends with regulation of a downstream cellular process, e.g. transcription. [GOC:mah, ISBN:0815316194]
synaptic transmission, cholinergicbiological processThe vesicular release of acetylcholine from a presynapse, across a chemical synapse, the subsequent activation of dopamine 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, Wikipedia:Cholinergic]
nervous system developmentbiological processThe process whose specific outcome is the progression of nervous tissue over time, from its formation to its mature state. [GOC:dgh]
positive regulation of insulin secretionbiological processAny process that activates or increases the frequency, rate or extent of the regulated release of insulin. [GOC:mah]
protein modification processbiological processThe covalent alteration of one or more amino acids occurring in proteins, peptides and nascent polypeptides (co-translational, post-translational modifications). Includes the modification of charged tRNAs that are destined to occur in a protein (pre-translation modification). [GOC:bf, GOC:jl]
positive regulation of smooth muscle contractionbiological processAny process that activates or increases the frequency, rate or extent of smooth muscle contraction. [GOC:go_curators]
saliva secretionbiological processThe regulated release of saliva from the salivary glands. In man, the saliva is a turbid and slightly viscous fluid, generally of an alkaline reaction, and is secreted by the parotid, submaxillary, and sublingual glands. In the mouth the saliva is mixed with the secretion from the buccal glands. In man and many animals, saliva is an important digestive fluid on account of the presence of the peculiar enzyme, ptyalin.

acetylcholine receptor signaling pathwaybiological processThe series of molecular signals generated as a consequence of an acetylcholine receptor binding to one of its physiological ligands. [GOC:mah]
G protein-coupled serotonin receptor signaling pathwaybiological processThe series of molecular signals generated as a consequence of a G protein-coupled serotonin receptor binding to one of its physiological ligands. [GOC:mah]
ion channel modulating, G protein-coupled receptor signaling pathwaybiological processThe series of molecular signals generated as a consequence of a G protein-coupled receptor binding to its physiological ligand, where the pathway proceeds through activation or inhibition of an ion channel. [GOC:dos]
ligand-gated ion channel signaling pathwaybiological processThe series of molecular signals initiated by activation of a ligand-gated ion channel on the surface of a cell. The pathway begins with binding of an extracellular ligand to a ligand-gated ion channel and ends with a molecular function that directly regulates a downstream cellular process, e.g. transcription. [GOC:bhm, PMID:25869137]
regulation of smooth muscle contractionbiological processAny process that modulates the frequency, rate or extent of smooth muscle contraction. [GOC:go_curators]
G protein-coupled receptor signaling pathway, coupled to cyclic nucleotide second messengerbiological processA G protein-coupled receptor signaling pathway in which the signal is transmitted via the activation or inhibition of a nucleotide cyclase activity and a subsequent change in the concentration of a cyclic nucleotide. [GOC:mah, GOC:signaling, ISBN:0815316194]
adenylate cyclase-inhibiting G protein-coupled acetylcholine receptor signaling pathwaybiological processAn adenylate cyclase-inhibiting G protein-coupled receptor signaling pathway initiated by acetylcholine binding to its receptor, and ending with the regulation of a downstream cellular process. [GOC:dph, GOC:mah, GOC:signaling, GOC:tb]
chemical synaptic transmissionbiological processThe vesicular release of classical neurotransmitter molecules from a presynapse, across a chemical synapse, the subsequent activation of neurotransmitter 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:jl, MeSH:D009435]
