Chain A   (ADRB1_RAT | P18090)
molecular function
    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:0005088    Ras guanyl-nucleotide exchange factor activity    Stimulates the exchange of guanyl nucleotides associated with a GTPase of the Ras superfamily. Under normal cellular physiological conditions, the concentration of GTP is higher than that of GDP, favoring the replacement of GDP by GTP in association with the GTPase.
    GO:0004935    adrenergic receptor activity    Combining with epinephrine or norepinephrine and transmitting the signal across the membrane by activating the alpha-subunit of an associated heterotrimeric G-protein complex.
    GO:0004940    beta1-adrenergic receptor activity    Combining with epinephrine or norepinephrine to initiate a change in cell activity via activation of a G protein, with pharmacological characteristics of beta1-adrenergic receptors.
    GO:0035240    dopamine binding    Interacting selectively and non-covalently with dopamine, a catecholamine neurotransmitter formed by aromatic-L-amino-acid decarboxylase from 3,4-dihydroxy-L-phenylalanine.
    GO:0008144    drug binding    Interacting selectively and non-covalently with a drug, any naturally occurring or synthetic substance, other than a nutrient, that, when administered or applied to an organism, affects the structure or functioning of the organism; in particular, any such substance used in the diagnosis, prevention, or treatment of disease.
    GO:0051379    epinephrine binding    Interacting selectively and non-covalently with epinephrine, a hormone produced by the medulla of the adrenal glands that increases heart activity, improves the power and prolongs the action of muscles, and increases the rate and depth of breathing. It is synthesized by the methylation of norepinephrine.
    GO:0051380    norepinephrine binding    Interacting selectively and non-covalently with norepinephrine, (3,4-dihydroxyphenyl-2-aminoethanol), a hormone secreted by the adrenal medulla and a neurotransmitter in the sympathetic peripheral nervous system and in some tracts of the CNS. It is also the biosynthetic precursor of epinephrine.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    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.
    GO:0005057    signal transducer activity, downstream of receptor    Conveys a signal from an upstream receptor or intracellular signal transducer, converting the signal into a form where it can ultimately trigger a change in the state or activity of a cell.
biological process
    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:0007266    Rho protein signal transduction    A series of molecular signals within the cell that are mediated by a member of the Rho family of proteins switching to a GTP-bound active state.
    GO:0007189    adenylate cyclase-activating G-protein coupled receptor signaling pathway    The 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 of adenylyl cyclase activity and a subsequent increase in the concentration of cyclic AMP (cAMP).
    GO:0071880    adenylate cyclase-activating adrenergic receptor signaling pathway    The series of molecular signals generated as a consequence of an adrenergic receptor binding to its physiological ligand, where the pathway proceeds with activation of adenylyl cyclase and a subsequent increase in the concentration of cyclic AMP (cAMP).
    GO:0007568    aging    A developmental process that is a deterioration and loss of function over time. Aging includes loss of functions such as resistance to disease, homeostasis, and fertility, as well as wear and tear. Aging includes cellular senescence, but is more inclusive. May precede death and may succeed developmental maturation (GO:0021700).
    GO:0006915    apoptotic process    A programmed cell death process which begins when a cell receives an internal (e.g. DNA damage) or external signal (e.g. an extracellular death ligand), and proceeds through a series of biochemical events (signaling pathway phase) which trigger an execution phase. The execution phase is the last step of an apoptotic process, and is typically characterized by rounding-up of the cell, retraction of pseudopodes, reduction of cellular volume (pyknosis), chromatin condensation, nuclear fragmentation (karyorrhexis), plasma membrane blebbing and fragmentation of the cell into apoptotic bodies. When the execution phase is completed, the cell has died.
    GO:0005980    glycogen catabolic process    The chemical reactions and pathways resulting in the breakdown of glycogen, a polydisperse, highly branched glucan composed of chains of D-glucose residues.
    GO:0060080    inhibitory postsynaptic potential    A process that causes 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:0055088    lipid homeostasis    Any process involved in the maintenance of an internal steady state of lipid within an organism or cell.
    GO:0007613    memory    The activities involved in the mental information processing system that receives (registers), modifies, stores, and retrieves informational stimuli. The main stages involved in the formation and retrieval of memory are encoding (processing of received information by acquisition), storage (building a permanent record of received information as a result of consolidation) and retrieval (calling back the stored information and use it in a suitable way to execute a given task).
    GO:0045986    negative regulation of smooth muscle contraction    Any process that stops, prevents, or reduces the frequency, rate or extent of smooth muscle contraction.
    GO:0035811    negative regulation of urine volume    Any process that decreases the amount of urine excreted from the body over a unit of time.
    GO:0002025    norepinephrine-epinephrine-mediated vasodilation involved in regulation of systemic arterial blood pressure    A process that results in an increase in the diameter of an artery during the norepinephrine-epinephrine response to blood pressure change.
    GO:0043547    positive regulation of GTPase activity    Any process that activates or increases the activity of a GTPase.
    GO:0045762    positive regulation of adenylate cyclase activity    Any process that activates or increases the frequency, rate or extent of adenylate cyclase activity.
    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:0030819    positive regulation of cAMP biosynthetic process    Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of the nucleotide cAMP (cyclic AMP, adenosine 3',5'-cyclophosphate).
    GO:0043950    positive regulation of cAMP-mediated signaling    Any process which activates, maintains or increases the frequency, rate or extent of cAMP-mediated signaling, a series of molecular signals in which a cell uses cyclic AMP to convert an extracellular signal into a response.
    GO:2001259    positive regulation of cation channel activity    Any process that activates or increases the frequency, rate or extent of cation channel activity.
    GO:0061051    positive regulation of cell growth involved in cardiac muscle cell development    Any process that increases the rate, frequency, or extent of the growth of a cardiac muscle cell, where growth contributes to the progression of the cell over time from its initial formation to its mature state.
    GO:0045823    positive regulation of heart contraction    Any process that activates or increases the frequency, rate or extent of heart contraction.
    GO:0010460    positive regulation of heart rate    Any process that activates or increases the frequency or rate of heart contraction.
    GO:0001996    positive regulation of heart rate by epinephrine-norepinephrine    The process in which the presence of epinephrine or norepinephrine in the bloodstream activates, maintains or increases the rate of heart contraction.
    GO:1900273    positive regulation of long-term synaptic potentiation    Any process that activates or increases the frequency, rate or extent of long-term synaptic potentiation.
    GO:1900135    positive regulation of renin secretion into blood stream    Any process that activates or increases the frequency, rate or extent of renin secretion into blood stream.
    GO:0046878    positive regulation of saliva secretion    Any process that activates or increases the frequency, rate or extent of the regulated release of saliva.
    GO:0003084    positive regulation of systemic arterial blood pressure    The process that increases the force with which blood travels through the systemic arterial circulatory system.
    GO:0003061    positive regulation of the force of heart contraction by norepinephrine    The process in which the secretion of norepinephrine into the bloodstream or released from nerve endings modulates the force of heart musclecontraction.
    GO:0033365    protein localization to organelle    A process in which a protein is transported to, or maintained in, a location within an organelle.
    GO:0051924    regulation of calcium ion transport    Any process that modulates the frequency, rate or extent of the directed movement of calcium ions into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0086004    regulation of cardiac muscle cell contraction    Any process that modulates the frequency, rate or extent of cardiac muscle cell contraction.
    GO:0019233    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. Pain is medically defined as the physical sensation of discomfort or distress caused by injury or illness, so can hence be described as a harmful stimulus which signals current (or impending) tissue damage. Pain may come from extremes of temperature, mechanical damage, electricity or from noxious chemical substances. This is a neurological process.
    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.
    GO:0042060    wound healing    The series of events that restore integrity to a damaged tissue, following an injury.

Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0005634    nucleus    A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
    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.
