Protein detail:


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.

Evidence M containing the K50A or the E231A mutation formed virus-like filaments (Fig. 5A, middle, rows 3 and 8, respectively) and N localized to cytoplasmic IBs and to virus-like filaments. In contrast, in cells expressing M with the S63A, S63E, N93A, or Y229A mu
