Abstract
Free polyribosomes isolated from mouse myeloma cells in tissue culture synthesize immunoglobulin chains. The presence of these peptide chains in the cytoplasm of intact myeloma cells has been investigated. Some immunoglobulin chains were observed, but it could not be ruled out that these were originally inside cisternae of the endoplasmic reticulum, which were broken during hogenization. We have also investigated the transport of the hypothetical cytoplastic immunoglobulins into the cisternae of the endoplasmic reticulum after incubation with radioactive amino acids and subsequent chase in the absence of protein synthesis. A model to account for synthesis of immunoglobulins on free polysomes is presented. This model assigns specificity for translation on membrane-bound polysomes to the N-terminal region of secretory proteins.
