Nonsegmented negative-sense (NNS) RNA viruses, Mononegavirales, cap their mRNA by an unconventional mechanism. Specifically, 5'-monophosphate mRNA is transferred to GDP derived from GTP through a reaction that involves a covalent intermediate between the large polymerase protein L and mRNA. The V region is essential for this process [1].
