    GO ID   Ontology GO Term Definition
    160   Phosphorelay Signal Transduction System  A Conserved Series of Molecular Signals Found in Prokaryotes and Eukaryotes; Involves Autophosphorylation of a Histidine Kinase and the Transfer of the Phosphate Group to an Aspartate That Then Acts As a Phospho Donor to Response Regulator Proteins. 
    6813   Potassium Ion Transport  The Directed Movement of Potassium Ions (k+) Into Out of or Within a Cell or Between Cells by Means of Some Agent Such As a Transporter or Pore. 
    7165   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. 
    16020   Membrane  Double Layer of Lipid Molecules That Encloses All Cells and in Eukaryotes Many Organelles; May Be a Single or Double Lipid Bilayer; Also Includes Associated Proteins. 
    155   Phosphorelay Sensor Kinase Activity  Catalysis of the Phosphorylation of a Histidine Residue in Response to Detection of an Extracellular Signal Such As a Chemical Ligand or Change in Environment to Initiate a Change in Cell State or Activity. the Two Component Sensor Is a Histidine Kinase That Autophosphorylates a Histidine Residue in Its Active Site. the Phosphate Is Then Transferred to an Aspartate Residue in a Downstream Response Regulator to Trigger a Response. 
    4871   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. 
    5249   Voltage Gated Potassium Channel Activity  Catalysis of the Transmembrane Transfer of a Potassium Ion by a Voltage Gated Channel. a Voltage Gated Channel Is a Channel Whose Open State Is Dependent On the Voltage Across the Membrane in Which It Is Embedded.
