In addition to participating in the assembly in the cytoplasm and budding of progeny virions at the cell membrane later in infection [5], the NDV M protein is localized in the nucleus and nucleolus early in infection [6], which is thought to inhibit host cell transcription and protein synthesis similar to the M protein of human respiratory syncytial virus (HRSV), vesicular stomatitis virus (VSV) and MeV [7–9]. This evidence concerns the gene MYOM2 and infection.
