alphacoronavirus Membrane (or Matrix) protein; This subfamily contains the Membrane (M) protein of alphacoronaviruses including human coronaviruses (HCoVs), HCoV-229E and HCoV-NL63. There are five essential genes in CoVs that result in the following gene products: Spike (S) protein, Membrane (M) glycoprotein, Nucleocapsid (N), Envelope (E) protein, and the Orf1ab (a large polyprotein known as replicase/protease); all are required to produce a structurally complete viral particle. The M protein, a triple-spanning membrane protein, is the most abundant protein in the virion. It plays a central role in virion assembly and morphogenesis, and it defines the shape of the viral envelope. It is regarded as the central organizer of CoV assembly, interacting with all other major coronaviral structural proteins and turning cellular membranes into workshops where virus and host factors come together to make new virus particles. While homotypic interactions between the M proteins are the major driving force behind virion envelope formation, it needs to interact with other coronaviral structural proteins for complete virion formation. The interaction of the Spike protein with M is not required for the assembly process. However, binding of M to N protein stabilizes the nucleocapsid (N protein-RNA complex), as well as the internal core of virions, and thereby promotes completion of viral assembly. Thus, the M protein, and its interactions with other structural proteins, is necessary for the production and release of virus-like particles.

49-256 1.69e-106

Coronavirus M matrix/glycoprotein; This family consists of various coronavirus matrix proteins which are transmembrane glycoproteins. The membrane (M) protein is the most abundant structural protein and defines the shape of the viral envelope, being the central organizer of coronavirus assembly. M proteins play a critical role in protein-protein interactions (as well as protein-RNA interactions) since virus-like particle (VLP) formation in many CoVs requires only the M and envelope (E) proteins for efficient virion assembly. Interaction of spike (S) with M is necessary for retention of S in the ER-Golgi intermediate compartment (ERGIC)/Golgi complex and its incorporation into new virions; binding of M to nucleocapsid (N) proteins stabilizes the nucleocapsid. Together, M and E protein make up the viral envelope and their interaction is sufficient for the production and release of virus-like particles (VLPs).

Membrane (or Matrix) protein from human coronavirus and related betacoronaviruses in the A lineage; This group contains the Membrane (M) protein of human coronaviruses (HCoVs), HCoV-OC43 and HCoV-HKU1, and similar proteins from betacoronaviruses in the embecovirus subgenera (A lineage). There are five essential genes in CoVs that result in the following gene products: Spike (S) protein, Membrane (M) glycoprotein, Nucleocapsid (N), Envelope (E) protein, and the Orf1ab (a large polyprotein known as replicase/protease); all are required to produce a structurally complete viral particle. The M protein, a triple-spanning membrane protein, is the most abundant protein in the virion. It plays a central role in virion assembly and morphogenesis, and it defines the shape of the viral envelope. It is regarded as the central organizer of CoV assembly, interacting with all other major coronaviral structural proteins and turning cellular membranes into workshops where virus and host factors come together to make new virus particles. While homotypic interactions between the M proteins are the major driving force behind virion envelope formation, it needs to interact with other coronaviral structural proteins for complete virion formation. The interaction of the Spike protein with M is not required for the assembly process. However, binding of M to N protein stabilizes the nucleocapsid (N protein-RNA complex), as well as the internal core of virions, and thereby promotes completion of viral assembly. Thus, the M protein, and its interactions with other structural proteins, is necessary for the production and release of virus-like particles.
