| Protein name | Matrix Protein |
| Uniprot protein ID | P0DOE7 |
| Protein length | 256 amino acids |
| Protein description | Matrix Protein, a non-glycosylated inner virion protein, plays a central role in infection. It is smaller than its paramyxovirus counterparts (256 a.a as compared to 335-375 a.a) and shares no clear sequence homology with them. All paramyxovirus M proteins are known to be strongly membrane-associated and have similar hydropathy profiles. There is a common region of low hydrophobicity at the N-terminus followed by a gradual increase in hydrophobic value towards the C-terminus, which includes a highly hydrophobic region. The hydrophobic regions are smaller than the minimum required for a transmembrane domain, but may mediate peripheral attachment to the host cell membrane. |
