CC   -!- FUNCTION: The M protein has a crucial role in virus assembly and
CC       interacts with the RNP complex as well as with the viral membrane.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the morbillivirus/respirovirus/rubulavirus M
CC       protein family. {ECO:0000305}.
