Encapsidates the genome, protecting it from nucleases. The encapsidated genomic RNA is termed the nucleocapsid (NC), and serves as template for viral transcription and replication (By similarity). Belongs to the tenuiviruses nucleocapsid protein family. This protein is few amino acids shorter in its N-terminus than to all other tenuiviruses. It has been described as N-acetylated unlike all other negative stranded virus nucleoproteins. Since no genome sequence is available for this virus, the N-acetylmethionine may be an artifact of protein sequencing.
