Previous studies indicate that one M-N interaction occurs between M protein and the carboxy-terminus of N protein. However, the mechanistic details of M-N interactions remain unclear. Here, we present a complex structure of an N protein carboxy-terminal peptide bound to M protein from Pipistrellus bat coronavirus HKU5. The structure shows that the M-N peptide binding site includes a "horizontal" groove located between the carboxy-terminal domain and the transmembrane domain of M protein. Combined with molecular docking and binding analysis, our results provide structural insight into the binding mechanism between M and N proteins of a coronavirus.
