GproteinDb

GproteinDb (G protein database) offers:

  • Reference data (see Data box)
  • Analysis tools (browse menu)
  • Visualization (e.g., snakeplots)
  • Experiment design (Coupling determinant mutations)
  • Data deposition (for G protein couplings and interface mutations)


G proteins are the main mediators of GPCR signaling1. Their activation is followed by recruitment of arrestins that arrest (stop) signaling or scaffold additional signaling proteins. There are 16 human G protein subtypes from 4 families that can be involved in biased signaling.
