Extended Data Figure 2. Comparison of protein amino acid sequence conservation to known morbilliviruses.

The percent amino acid similarity (% AA) of MBaMV proteins compared to the 7 established morbilliviruses are plotted to visualize the degree of conservation across the genus. N, M, F, and L showed relatively high conservation (50 – 80%) to all morbilliviruses with the exception FeMV. P, V, C and RBP showed 30-50% conservation to all morbilliviruses again with the exception of FeMV. ClustalW was used to align the cognate amino acid sequences from each morbillivirus and the % AA similarity was calculated using default settings. The accession number of the sequences used are indicated in Extended Data Table 1.
