Co-translational targeting of membrane and secretory proteins is mediated by the universally conserved Signal Recognition Particle (SRP). Together with its receptor (SR), SRP mediates the GTP-dependent delivery of translating ribosomes bearing signal sequences to translocons on the target membrane. Here we present the crystal structure of the SRP:SR complex at 3.9 Å resolution and biochemical data revealing that the activated SRP:SR GTPase complex bind the distal end of the SRP hairpin RNA where GTP hydrolysis is stimulated. Combined with previous findings, these results suggest that the SRP:SR GTPase complex initially assembles at the tetraloop end of the SRP RNA and then relocalizes to the opposite end of the RNA. This rearrangement provides a mechanism for coupling GTP hydrolysis to the handover of cargo to the translocon.
