| The phosphoprotein (P) is virally encoded by the Rhabdoviridae and Paramyxoviridae in the order Mononegavirales. P is a self-associated oligomer and forms complexes with the large viral polymerase protein (L), the nucleocapsid protein (N), and the assembled nucleocapsid. P from different viruses has shown structural diversities even though their essential functions are the same. We systematically mapped the domains in mumps virus (MuV) P and investigated their interactions with nucleocapsid-like particles (NLPs). Similar to other P proteins, MuV P contains N-terminal, central, and C-terminal domains with flexible linkers between neighboring domains. By pulldown assays, we discovered that in addition to the previously proposed nucleocapsid binding domain (residues 343-391), the N-terminal region of MuV P (residues 1-194) could also bind NLP. Further analysis of binding kinetics was conducted using surface plasmon resonance. This is the first observation that both the N- and C-terminal regions of a negative strand RNA virus P are involved in binding the nucleocapsid. Additionally, we defined the oligomerization domain (POD) of MuV P as residues 213-277 and determined its crystal structure. The tetrameric MuV POD is formed by one pair of long parallel alpha-helices with another pair in opposite orientation. Unlike the parallel orientation of each alpha-helix in the tetramer of Sendai virus POD, this represents a novel orientation of a POD where both the N- and C-terminal domains are at either end of the tetramer. This is consistent with the observation that both the N- and C-terminal domains are involved in binding the nucleocapsid.
