This entry represents the N-terminal domain found in a variety of paramyxoviruses such as Morbillivirus, paramyxovirus, pneumovirus M proteins. The N-terminal domain of the NDV matrix protein consists of residues 1-181. It adopts a beta-sandwich fold in which the beta-strands in the opposing beta-sheets are approximately orthogonal to each other. Several alpha-helices are situated mostly on the surface of this beta-sandwich domain. The N-terminal domain is connected to a C-terminal domain with similar fold via a 16 amino acid linker. The two domains are related by an approximate fourfold rotation axis coincident with the twofold axis of the matrix protein dimer. The matrix protein dimer represents the physiologically relevant assembly unit. The N-terminal domain contributes to the highly positively charged surface that faces the viral membrane, enabling association with the negatively charged membrane [1].
