CC -!- FUNCTION: Plays an essential role in the inhibition of host immune
CC response. Prevents the establishment of cellular antiviral state by
CC blocking interferon-alpha/beta (IFN-alpha/beta) production and
CC signaling pathway. Interacts with host IFIH1/MDA5 and DHX58/LGP2 to
CC inhibit the transduction pathway involved in the activation of IFN-beta
CC promoter, thus protecting the virus against cell antiviral state.
CC Blocks the type I and II interferon signaling pathways by interacting
CC with host STAT1, STAT2 and STAT3, and mediating their ubiquitination
CC and subsequent proteasomal degradation (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Interacts with host IFIH1/MDA5 and DHX58/LGP2. Forms with host
CC DDB1, CUL4A, STAT1, STAT2 and STAT3 the mumps virus V-dependent complex
CC (VDC) (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Host cytoplasm {ECO:0000250}.
CC -!- RNA EDITING: Modified_positions=155 {ECO:0000269|PubMed:2165137};
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 P60166).;
CC -!- SIMILARITY: Belongs to the paramyxoviruses V protein family.
CC {ECO:0000305}.
