    Chain A
    GO ID   Ontology GO Term Definition
    6184   Obsolete GTP Catabolic Process  Obsolete. the Chemical Reactions and Pathways Resulting in the Breakdown of GTP Guanosine Triphosphate. 
    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. 
    7264   Small Gtpase Mediated Signal Transduction  Any Series of Molecular Signals in Which a Small Monomeric Gtpase Relays One or More of the Signals. 
    15031   Protein Transport  The Directed Movement of Proteins Into Out of or Within a Cell or Between Cells by Means of Some Agent Such As a Transporter or Pore. 
    5622   Intracellular  The Living Contents of a Cell; the Matter Contained Within (but Not Including) the Plasma Membrane Usually Taken to Exclude Large Vacuoles and Masses of Secretory or Ingested Material. in Eukaryotes It Includes the Nucleus and Cytoplasm. 
    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. 
    5525   GTP Binding  Interacting Selectively and Non Covalently with GTP Guanosine Triphosphate.
