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. Might be involved, through interaction with
CC host dynein, in intracellular microtubule-dependent virus transport of
CC incoming virus from the synapse toward the cell body (By similarity).
CC {ECO:0000250}.
CC -!- SUBUNIT: [Phosphoprotein]: Homotrimer when phosphorylated. This trimer
CC is stabilized by binding to the L protein. Binds soluble protein N, and
CC ribonucleocapsid. Interacts with host DYNLL1 and DYNLL2; this
CC interaction may play a role in intracellular microtubule-dependent
CC virus transport of incoming virus. Interacts with host STAT1, STAT2 and
CC PML. {ECO:0000250}.
CC -!- SUBUNIT: [Isoform P3]: Binds host PML (By 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}.
