GPCRdb (G protein-coupled receptor database) is a community hub offering:

  • Reference data (see Data box)
  • Analysis tools (browse menu)
  • Visualization (e.g., snakeplots)
  • Experiment design (overview)
  • Data deposition (e.g., ligand site mutations)

GPCRs are cell-surface receptors mediating the responses of 2/3rds of human hormones1 and 1/3rd of drugs2. Each GPCR can bind several transducers, G proteins, GPCR kinases (GRKs) and arrestins leading to distinct intracellular signaling networks and functional outcomes.
