Cardiac tropomyosin from 20-day-old chick embryos is composed of three different polypeptides with the same molecular weight but different isoelectric points. These polypeptides, which are designated as α1, α2, and α3, have identical peptide maps. In vitro, however, only polypeptide α1 is synthesized in a reticulocyte lysate programmed with cardiac RNA. These results, together with the observations indicating that tropomyosin α2 corresponds to a phosphorylated polypeptide, suggest that only tropomyosin α1 corresponds to a primary translational product and that forms α2 and α3 are derived from α1 as a consequence of posttranslational modifications.
