The phosphoprotein (P) of rabies virus binds the viral polymerase to the, nucleoprotein (N)-RNA template for transcription and replication. By, limited protease digestion we defined a monomeric C-terminal domain of P, that can bind to N-RNA. The atomic structure of this domain was determined, and previously described mutations that interfere with binding of P to, N-RNA could now be interpreted. There appears to be two features involved, in this activity situated at opposite surfaces of the molecule: a, positively charged patch and a hydrophobic pocket with an exposed, tryptophan side-chain. Other previously published work suggests a, conformational change in P when it binds to N-RNA, which may imply the, repositioning of two helices that would expose a hydrophobic groove for, interaction with N. This domain of rabies virus P is structurally, unrelated to the N-RNA binding domains of the phosphoproteins of Sendai, and measles virus that are members of the same order of viruses, the, non-segmented negative strand RNA viruses. The implications of this, finding for the evolution of this virus group are discussed.

== Function ==
 +
[https://www.uniprot.org/uniprot/PHOSP_RABVC PHOSP_RABVC] Non catalytic polymerase cofactor and regulatory protein that plays a role in viral transcription and replication. Stabilizes the RNA polymerase L to the N-RNA template and binds the soluble protein N, preventing it from encapsidating non-genomic RNA. Also inhibits host IFN-alpha and IFN-beta signaling by binding and retaining phosphorylated STAT1 in the cytoplasm or by inhibiting the DNA binding of STAT1 in the nucleus. Might be involved, through interaction with host dynein, in intracellular microtubule-dependent virus transport of incoming virus from the synapse toward the cell body.

The phosphoprotein (P) of rabies virus binds the viral polymerase to the nucleoprotein (N)-RNA template for transcription and replication. By limited protease digestion we defined a monomeric C-terminal domain of P that can bind to N-RNA. The atomic structure of this domain was determined and previously described mutations that interfere with binding of P to N-RNA could now be interpreted. There appears to be two features involved in this activity situated at opposite surfaces of the molecule: a positively charged patch and a hydrophobic pocket with an exposed tryptophan side-chain. Other previously published work suggests a conformational change in P when it binds to N-RNA, which may imply the repositioning of two helices that would expose a hydrophobic groove for interaction with N. This domain of rabies virus P is structurally unrelated to the N-RNA binding domains of the phosphoproteins of Sendai and measles virus that are members of the same order of viruses, the non-segmented negative strand RNA viruses. The implications of this finding for the evolution of this virus group are discussed.
