G protein-coupled receptor signaling pathway(GO:0007186)biological_processA 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. The pathway can start from the plasma membrane, Golgi or nuclear membrane (PMID:24568158 and PMID:16902576).

 

Click on the GO term name to get the PDB entries for which a UniProt entry annotated with this GO term is available. This covers the query level and all lower hierarchical levels.

Click on the GO accession number to get a tree view of the GO hierarchy without information on PDB entries. In this case your query level and all levels of higher hierarchy up to the root level Gene_Ontology (GO:0003673) are displayed.

If you enter the GO tree somewhere and if you want to get a view of the whole tree first click on the GO name. This yields the low-hierarchy part. Then click on the GO accession number of the lowest hierarchical level. This gives a view of the complete tree. Note, that certain GO terms belong to more than one path.
