摘要

Nipah virus (NiV) is predicted to encode four proteins from its P gene (P, V, W, and C) via mRNA editing and an alternate open reading frame. By use of specific antibodies, the expression of the V, W, and C proteins in NiV-infected cells has now been confirmed. Analysis of the P-gene transcripts shows a ratio of P:V:W mRNA of 1:1:1, but this differs over time, with greater proportions of V and W transcripts observed as the infection progresses. Eighty-two percent of transcripts are edited, with up to 11 G insertions observed. This exceptionally high editing frequency ensures expression of the V and W proteins.
