    Chain A
    GO ID   Ontology GO Term Definition
    35023   Regulation of Rho Protein Signal Transduction  Any Process That Modulates the Frequency Rate or Extent of Rho Protein Signal Transduction. 
    38032   Termination of G Protein Coupled Receptor Signaling Pathway  The Signaling Process in Which G Protein Coupled Receptor Signaling Is Brought to an End. For Example Through the Action of Gtpase Activating Proteins (gaps) That Act to Accelerate Hydrolysis of GTP to GDP On G Alpha Proteins Thereby Terminating the Transduced Signal. 
    43547   Positive Regulation of Gtpase Activity  Any Process That Activates or Increases the Activity of a Gtpase. 
    5089   Rho Guanyl Nucleotide Exchange Factor Activity  Stimulates the Exchange of Guanyl Nucleotides Associated with a Gtpase of the Rho Family. 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.
