The membrane (M) protein (previously called E1, sometimes also matrix protein[2]) is an integral membrane protein that is the most abundant of the four major structural proteins found in coronaviruses.[3][4][5] The M protein organizes the assembly of coronavirus virions through protein-protein interactions with other M protein molecules as well as with the other three structural proteins, the envelope (E), spike (S), and nucleocapsid (N) proteins.[4][6][7][8]
