Ribosomes are classified as being either "free" or "membrane-bound". Free and membrane-bound ribosomes differ only in their spatial distribution; they are identical in structure. Whether the ribosome exists in a free or membrane-bound state depends on the presence of an ER-targeting signal sequence on the protein being synthesized, so an individual ribosome might be membrane-bound when it is making one protein, but free in the cytosol whe… WebJan 31, 2024 · These proteins, also called regulatory nascent chains, interact co-translationally with the ribosomes and arrest translation elongation or termination of their own (1–4,). Thus, they are also referred to as ribosome arrest peptides (RAP) ( 5 , ) or, simply, arrest peptides.
