The bulk of the phosphorylation of human respiratory syncytial virus phosphoprotein is not essential but modulates viral RNA transcription and replication Villanueva, Nieves and Hardy, Richard and Asenjo, Ana and Yu, Qingzhong and Wertz, Gail,, 81, 129-133 (2000), doi = https://doi.org/10.1099/0022-1317-81-1-129, publicationName = Microbiology Society, issn = 0022-1317, 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 The serine residues normally phosphorylated in P during HRSV infection have been replaced by other residues.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., language=, type=
