In the virus - infected cells , translation of the M1 protein was reduced to 10 to 20 % of that of the wild - type virus ; however , the translation of neither the nucleoprotein nor NS1 was significantly interfered with , indicating the important role of NS1 in translational stimulation of the M1 protein .
