| Uniprot protein ID | P35976 |

| Protein description | The M protein is thought to drive MeV assembly by physically recruiting the RNP and glycoproteins to the host cell plasma membrane. Studies have shown that altered interaction between M and the cytoplasmic tail of H or F affects MeV viral growth, indicating the necessity for contacts between M and the glycoproteins during assembly. Recent structural studies of NDV by cryo-ET and X-ray crystallography demonstrated that the RNP complex is aligned with M protein arrays16. Furthermore, it has been suggested that actin filaments play a role in the MeV assembly and budding process by facilitating the transportation of M-RNP complexes. |

| Title | Altered interaction of the matrix protein with the cytoplasmic tail of hemagglutinin modulates measles virus growth by affecting virus assembly and cell-cell fusion |

| Evidence | When the cytoplasmic tail of the H protein is deleted, a virus with an M protein possessing the P64S and E89K substitutions no longer grows well in Vero cells yet causes cell-cell fusion and replicates efficiently in B95a cells. |
