The names of genes, designated according to proteins encoded by each, are indicated. NP, nucleoprotein; VP35, viral protein 35; VP40, viral protein 40; GP/sGP, glycoprotein, soluble glycoprotein; VP30, viral protein 30; VP24, viral protein 24; L, Large protein (the viral polymerase). Note that Marburg virus encodes GP but not sGP. The spacing between genes is variable and is not drawn to scale.
