    GO ID   Ontology GO Term Definition
    6940   Regulation of Smooth Muscle Contraction  Any Process That Modulates the Frequency Rate or Extent of Smooth Muscle Contraction. 
    7186   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. 
    7189   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). 
    42312   Regulation of Vasodilation  Any Process That Modulates the Frequency Rate or Extent of Increases in the Diameter of Blood Vessels. 
    16021   Integral Component of Membrane  The Component of a Membrane Consisting of Gene Products and Protein Complexes That Have Some Part That Penetrates At Least One Leaflet of the Membrane Bilayer. This Component Includes Gene Products That Are Buried in the Bilayer with No Exposure Outside the Bilayer. 
    4930   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. 
    4935   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. 
    4941   Beta2 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 Beta2 Adrenergic Receptors.
