Abstract

The ability of variants of the human respiratory syncytial virus (HRSV) phosphoprotein (P protein) to support RNA transcription and replication has been studied by using HRSV-based subgenomic replicons. The serine residues normally phosphorylated in P during HRSV infection have been replaced by other residues. The results indicate that the bulk of phosphorylation of P (98%) is not essential for viral RNA transcription or replication but that phosphorylation can modulate these processes.
