    12 different G protein-coupled receptors (GPCRs) through selective coupling of Gs, Gi, or Gq proteins The structural basis for G protein subtype selectivity by these GPCRs remains elusive. We find that the macro-switch by the TM5-TM6 length is shared by class A GPCR-G protein structures. Together, these results present a common mechanism of Gs versus Gi protein coupling selectivity or promiscuity by class A GPCRs and extend the basis of ligand recognition at serotonin receptors."
