Protein detail:


Protein name Matrix Protein
Uniprot protein ID P35976
Protein length 335 amino acids
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
Author Maino Tahara,Makoto Takeda,Yusuke Yanagi
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.
