[Addressed protein transport in the cell].

The paper summarizes data on the nature of signals (mainly amino acid sequences) determining the intracellular movement of newly formed polypeptide chains: their secretion, incorporation into the cytoplasmic or endoplasmic reticular membranes, into different compartments of mitochondria and chloroplasts. Some information is given about the polypeptide transport into the nucleus and microbodies (glyoxysomes, peroxysomes, glucosomes). The intracellular movement of polypeptides is supposed to be proteolytically controlled.
