Electron-microscopic immunocytochemical study of the intracellular transport of the viral glycoproteins in ts1, a mutant of Moloney murine leukemia virus.
The transport and localization of env-proteins of ts1 virus (a paralytogenic temperature-sensitive mutant of Moloney murine leukemia virus) in infected cells of the TB cell line have been studied at the ultrastructural level. It was found that the envelope precursor polyprotein gPr80-env of ts1 was inefficiently transported out of the endoplasmic reticulum at the restrictive temperature. It was speculated that inefficient transport correlates with inefficient processing of gPr80env into gp70 and Prp15E and leads to paralytic disease.
