CC -!- FUNCTION: Non catalytic polymerase cofactor and regulatory protein that
CC plays a role in viral transcription and replication. Stabilizes the RNA
CC polymerase L to the N-RNA template and binds the soluble protein N,
CC preventing it from encapsidating non-genomic RNA. Also inhibits host
CC IFN-alpha and IFN-beta signaling by binding and retaining
CC phosphorylated STAT1 in the cytoplasm or by inhibiting the DNA binding
CC of STAT1 in the nucleus (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Homotrimer when phosphorylated. This trimer is stabilized by
CC binding to the L protein. Binds soluble protein N, and
CC ribonucleocapsid. Interacts with host STAT1, STAT2 and PML (By
CC similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: [Phosphoprotein]: Virion. Host cytoplasm
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: [Isoform P2]: Host cytoplasm {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: [Isoform P3]: Host nucleus {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: [Isoform P5]: Host nucleus {ECO:0000250}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative initiation; Named isoforms=4;
CC Name=P;
CC IsoId=Q5VKP5-1; Sequence=Displayed;
CC Name=P2;
CC IsoId=Q5VKP5-2; Sequence=VSP_026892;
CC Name=P3;
CC IsoId=Q5VKP5-3; Sequence=VSP_026891;
CC Name=P5;
CC IsoId=Q5VKP5-4; Sequence=VSP_026890;
CC -!- PTM: Phosphorylated by host PKC and by an unknown kinase.
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the lyssavirus protein P family. {ECO:0000305}.
