Before revision:  The first complex is related to Golgi transport and vesicle coating. Several viral proteins go through this complex before viral budding, the knock-down of Golgi related proteins might have prevented viral production. The second complex is related to ATP dependent proton transport. The uncoating of the  Influenza virus is dependent on pH changes within the endosome, knock-down of these genes may changes in the endosomal pH inhibiting the uncoating of the virus .
After revision:  The biological function and the Influenza virus is dependent on pH changes within the endosome, knock-down of these genes may changes in the endosomal pH inhibiting the uncoating of the virus .
