CC   -!- FUNCTION: Blocks host interferon signaling. {ECO:0000250}.
CC   -!- RNA EDITING: Modified_positions=153 {ECO:0000269|PubMed:2167560};
CC       Note=Partially edited. RNA editing at this position consists of an
CC       insertion of two guanine nucleotides. The sequence displayed here is
CC       the V protein, derived from the unedited RNA. The edited RNA gives rise
CC       to the P protein (AC P22044).;
CC   -!- SIMILARITY: Belongs to the paramyxoviruses V protein family.
CC       {ECO:0000305}.
