- 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.
