The Role of the Tunnel

Caption

The protein-sorting complex SRP scans the ribosome protein tunnel where proteins are being synthesized. When it recognizes a protein of the right kind, SRP positions its binding pocket at the end of the tunnel, where it forms a stable complex with the protein and transports it to the target site in the membrane.
