Intracellular synthesis of mouse mammary tumor virus polypeptides: indication of a precursor glycoprotein.

RESUMO
Mouse mammary tumor virus polypeptides were detected in the cytoplasm of mouse mammary tumor cell cultures using immunological precipitation techniques. The anti-mouse mammary tumor virus serum precipitated the major virion glycoproteins gp49 and gp37.5/33.5 and a viral-related nonvirion glycoprotein of 76,000 daltons. Subcellular fractionation studies revelaed that the cell-associated virion glycoproteins were present in the membrane fraction. Pulsechase experiments indicated that a viral-related nonvirion glycoprotein of 76,000 daltons may be a precursor to one or more of the virion glycoproteins.
