Target Background

Function
Plays critical roles in virus replication, from virus entry and uncoating to assembly and budding of the virus particle. M1 binding to ribonucleocapsids (RNPs) in nucleus seems to inhibit viral transcription. Interaction of viral NEP with M1-RNP is thought to promote nuclear export of the complex, which is targeted to the virion assembly site at the apical plasma membrane in polarized epithelial cells. Interactions with NA and HA may bring M1, a non-raft-associated protein, into lipid rafts. Forms a continuous shell on the inner side of the lipid bilayer in virion, where it binds the RNP. During virus entry into cell, the M2 ion channel acidifies the internal virion core, inducing M1 dissociation from the RNP. M1-free RNPs are transported to the nucleus, where viral transcription and replication can take place.; Determines the virion's shape: spherical or filamentous. Clinical isolates of influenza are characterized by the presence of significant proportion of filamentous virions, whereas after multiple passage on eggs or cell culture, virions have only spherical morphology. Filamentous virions are thought to be important to infect neighboring cells, and spherical virions more suited to spread through aerosol between hosts organisms.

  1. identification of a suppressor mutations in the M1 protein which complement a lethal M2 mutation by increasing the efficiency with which virus particles bud from infected cells and restoring filament formation at the infected-cell surface. PMID: 29046451
  2. Data indicate that Itch interacted with viral M1 protein and ubiquitinated M1 protein. PMID: 24101521
  3. M1 prevents repressional function of Daxx during infection, thereby exerting a survival role PMID: 23548901
  4. Tyrosine 132 phosphorylation of M1 protein is crucial for virus replication by controlling the nuclear import of M1. PMID: 23536660
  5. Neuraminidase and matrix proteins cooperate to facilitate efficient virus replication and transmissibility in pigs. PMID: 22337640
  6. We hypothesize that the specific 3D structural peculiarities of the M1 protein revealed in acidic pH solution allow the protein greater structural flexibility and enable it to interact effectively with the components of the host cell PMID: 21985378
  7. It is suggested, that influenza virus M1 polyfunctionality in infected cell is determined by its tertiary structure plasticity which in its turn results from the presence of unstructured regions. PMID: 21954602
  8. Data demonstrate that the C-terminal domain of NS2 (residues 81-100) is essential for M1 binding and the nuclear export of progeny vRNPs. PMID: 21081124
  9. attenuating mutations identified in Matrix gene of Influenza A/WSN/33 PMID: 15650216
  10. propose that a threshold amount of M1 protein is needed for the assembly of viral components into an infectious particle and that budding is delayed in Mmut virus-infected cells until sufficient levels of M1 protein accumulate at the plasma membrane PMID: 15919950
