Crystal structure of the membrane (M) protein from a bat betacoronavirus.
Pnas Nexus, 2:pgad021-pgad021, 2023

PubMed Abstract: The membrane (M) protein is the most abundant structural protein of coronaviruses including MERS-CoV, SARS-CoV, and SARS-CoV-2, and plays a central role in virus assembly through its interaction with various partner proteins. However, mechanistic details about how M protein interacts with others remain elusive due to lack of high-resolution structures. Here, we present the first crystal structure of a betacoronavirus M protein from bat coronavirus HKU5 (batCOV5-M), which is closely related to MERS-CoV, SARS-CoV, and SARS-CoV-2 M proteins. Furthermore, an interaction analysis indicates that the carboxy-terminus of the batCOV5 nucleocapsid (N) protein mediates its interaction with batCOV5-M. Combined with a computational docking analysis an M-N interaction model is proposed, providing insight into the mechanism of M protein-mediated protein interactions.
