Crystal structure of the Borna disease virus matrix protein (BDV-M) reveals ssRNA binding properties.

ABSTRACT: Borna disease virus (BDV) is a neurotropic enveloped RNA virus that causes a noncytolytic, persistent infection of the central nervous system in mammals. BDV belongs to the order Mononegavirales, which also includes the negative-strand RNA viruses (NSVs) Ebola, Marburg, vesicular stomatitis, rabies, mumps, and measles. BDV-M, the matrix protein (M-protein) of BDV, is the smallest M-protein (16.2 kDa) among the NSVs. M-proteins play a critical role in virus assembly and budding, mediating the interaction between the viral capsid, envelope, and glycoprotein spikes, and are as such responsible for the structural stability and individual form of virus particles. Here, we report the 3D structure of BDV-M, a full-length M-protein structure from a nonsegmented RNA NSV. The BDV-M monomer exhibits
