Abstract
The sequences of the genes encoding the putative attachment (G) proteins of pathogenic (strain J3666) mouse lung-passaged and nonpathogenic (strain 15) tissue culture-passaged strains of pneumonia virus of mice (PVM) have been determined. In both cases the major polypeptide was synthesised from the second open reading frame (ORF), a feature also found in the G gene of respiratory syncytial (RS) virus, another pneumovirus. However, the ORFs of the G genes of the two PVM strains were initialed at different nucleotide positions in the mRNA and comparison of hydrophobicity profiles revealed the presence of the putative amino-terminal cytoplasmic domain in the strain J3666 G protein and its absence in the predicted G protein of PVM strain 15. In common with the G protein of RS virus, the gene product of both PVM strains contained a high serine, threonine, and proline content Indirect immunofluorescence analysis of BSC-1 cells expressing the G gene products confirmed the surface location of the proteins. Thus, the absence of a cytoplasmic domain does not interfere with the translocation of the G protein of PVM strain 15. In vitro translation of mRNA from the two PVM genes directed the synthesis of a larger polypeptide with the G gene of PVM strain J3666 than was seen with the strain 15 G gene. In addition, a second protein was seen with strain J3666 mRNA which was the same size as the strain 15 G protein. (C) 1995 Academic Press, Inc.
