WebbA ribosome binding site, or ribosomal binding site (RBS), is a sequence of nucleotides … WebbWhen this sequence sticks out of the ribosome, it’s recognized by a protein complex called the signal-recognition particle (SRP), which takes the ribosome to the ER. There, the ribosome feeds its amino acid chain into the ER lumen (interior) as it's made.
