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.
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.
