Free and membrane-bound polyribosomes in BHK cells infected with Sindbis virus

G Martire et al. J Virol. 1977 Feb.

Abstract

The data presented in the paper demonstrate that in BHK cells infected with Sindbis virus virtually all the 42S mRNA not in nucleocapsid is associated with free polyribosomes, whereas the 26S mRNA is distributed between free and membrane-bound polyribosomes. We suggest that the 26S RNA polyribosomes are bound to the membranes through the nascent chains of the B1 protein and that a large percentage of 26S RNA polyribosomes free in the cytoplasm may be due to the small amount of rough endoplasmic reticulum in BHK cells. In addition, we found that intracellular nucleocapsid is in the nonmembrane fraction of the cytoplasm of infected cells.
