CC   -!- FUNCTION: Essential component of the RNA polymerase transcription and
CC       replication complex. Binds the viral ribonucleocapsid and positions the
CC       L polymerase on the template. May act as a chaperone for newly
CC       synthesized free N protein, so-called N(0). Plays a role in virion
CC       assembly (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Homotrimer when phosphorylated in domain I. This trimer is
CC       stabilized by binding to the L protein. Binds N(0), and N in
CC       ribonucleocapsid (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion. Host cytoplasm {ECO:0000250}.
CC   -!- DOMAIN: Sequences comparison studies have defined several domains.
CC       Domain I binds the protein L, contains phosphorylation sites required
CC       for trimerization and is involved in transcription. Hinge region is
CC       highly variable and may act as a spacer between domain I and II. Domain
CC       II is also phosphorylated, binds protein L, and plays a role in
CC       replication. Domain III is basic and essential for binding the N-RNA
CC       template (By similarity). {ECO:0000250}.
CC   -!- PTM: Domain I is phosphorylated by host CK2. Domain II is
CC       phosphorylated by other unknown kinases. Phosphorylation play an
CC       important role in facilitating trimerization and possibly P-L complex
CC       formation (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the vesiculovirus protein P family.
CC       {ECO:0000305}.
