Abstract

The paramyxovirus P protein is an essential component of the transcriptase and replicase complex along with L protein. In this article, we have examined the functional roles of different domains of P proteins of two closely related morbilliviruses, Rinderpest virus (RPV) and Peste des petits ruminants virus (PPRV). The PPRV P protein physically interacts with RPV L as well as RPV N protein when expressed in transfected cells, as shown by co-immunoprecipitation.The heterologous L–P complex is biologically active when tested in a RPV minigenome replication/transcription system, only when used with PPRV N protein but not with RPV N protein. Employing chimeric PPRV/RPV cDNAs having different coding regions of P protein in the minigenome replication/transcription system, we identified a region between 290 and 346 aa in RPV P protein necessary for transcription of the minigenome.
