Molecular cloning of the rinderpest virus matrix gene: comparative sequence analysis with other paramyxoviruses.
The nucleotide sequence of the gene encoding the matrix or membrane (M) protein of the virulent (Kabete-O) strain of rinderpest virus (RPV) has been determined. The M gene is 1457 nucleotides long with a single, large open reading frame. The derived polypeptide has 335 amino acids, corresponding to a calculated molecular weight of 38,289 and contains both small hydrophobic regions and many basic residues. The predicted amino acid sequence was compared to the M proteins of paramyxoviruses. Sequence comparison and hydropathy profiles among the morbilliviruses revealed that the M protein of RPV exhibits features similar to those of the M protein of MV and CDV. There is 78.2% homology at the amino acid level between the M protein of RPV and MV, and 77.6% between RPV and CDV. This indicates that a high degree of homology exists among the members of the genus Morbillivirus. In contrast, there is only 37.3 and 18% homology between RPV and bovine parainfluenza type 3 (BPV3), and RPV and Newcastle disease virus (NDV) M proteins, respectively. Thus the M proteins of the morbilliviruses are highly conserved whereas the M proteins of the genus Paramyxovirus show more divergence.
