John F. Foley<p>In Editors&#39; Choice in Science Signaling, I highlight a study by Park, Martemyanov, Garcia-Marcos, and colleagues revealing another level of bias in GPCR signaling. In the context of neurotransmission, the authors showed that the protein GINIP bound to GTP-bound Galphai subunits, preventing them from interacting with their effectors. As a result, signaling by Gbetagamma subunits was enhanced, biasing the response to GPCR stimulation.
