M protein is the most abundant component of the mature virionm and contributes to the shape of the virus. It consists of three transmembrane domains with an N-terminus outside the virus and an internal C-terminus (N-exo, C-endo conformation). Homotypic interactions between M proteins contribute to the initial formation of a nascent virus by forming a lattice, consistent with what is seen in other coronavirus systems (Tseng et al, 2010; de Hann et al, 1998; de Haan et al, 2000; Locker et al, 1995). Multiple segments of M are required for oligomerization (Tseng et al, 2010; de Hann et al, 1998; de Haan et al, 2000; reviewed in Masters, 2006). Both glycosylated and non-glycosylated forms of M are incorporated into the virion, and the significance of the N-linked glycosylation is not clear (Voss et al, 2006; Voss et al, 2009).
Despite its importance, expression of M alone is not sufficient to drive formation of a mature virus (reviewed in Masters, 2006). Protein-protein interactions between M and S, N and E, among other components, are required for assembly of a mature virus and for membrane curvature. Many studies have examined the minimal system required for release of viral like particles (VLPs) with sometimes contradictory results, but interactions between M, N and E are sufficient to promote release of significant numbers of VLPs (Ho et al, 2004; Huang et al, 2004; Mortola and Roy, 2004; Hsieh et al, 2005; Siu et al, 2008; Hatakeyama et al, 2008; Tseng et al, 2013; reviewed in Masters, 2006)
