Due to the occurrence of bias in the direction of mutation, these differences and those found in nucleotide sequences of different isolates of the minor component in the vaccine (MuVJL2<\/jats:sup>) might be due to the effect of ADAR-like deaminases on MuV grown in tissue-cultured cells. A molecular clone of MuVJL2<\/jats:sup> (pMuVJL2<\/jats:sup>) and MuVJL2<\/jats:sup>-specific helper plasmids were constructed in order to investigate molecular interactions between MuVJL5<\/jats:sup> and MuVJL2<\/jats:sup>, to augment the existing molecular clone of MuVJL5<\/jats:sup> (pMuVJL5<\/jats:sup>) and MuVJL5<\/jats:sup>-specific helper plasmids. Genome and mRNA termini of MuVJL2<\/jats:sup> were characterized, and an unusual oligo-G insertion transcriptional editing event was detected near the F mRNA polyadenylation site of MuVJL2<\/jats:sup>, but not of MuVJL5<\/jats:sup>. Genes encoding glycoproteins of rMuVJL2<\/jats:sup> and rMuVJL5<\/jats:sup> have been exchanged to characterize the oligo-G insertion, which associated with the specific sequence of the F gene of MuVJL2<\/jats:sup> and not with any other genes or the RNA-dependent RNA polymerase of strain MuVJL2<\/jats:sup>. The results indicate that a single G-to-A sequence change obliterates the co-transcriptional editing of the F mRNA and that this oligo-G insertion does not affect the growth of the virus.<\/jats:p>","DOI":"10.1099\/vir.0.013946-0","type":"journal-article","created":{"date-parts":[[2009,11,3]],"date-time":"2009-11-03T22:55:36Z","timestamp":1257288936000},"page":"2973-2981","source":"Crossref","is-referenced-by-count":25,"title":["Molecular differences between two Jeryl Lynn mumps virus vaccine component strains, JL5 and JL2"],"prefix":"10.1099","volume":"90","author":[{"given":"Phil","family":"Chambers","sequence":"first","affiliation":[{"name":"Centre for Infection and Immunity, School of Medicine, Dentistry and Biomedical Sciences, Medical Biology Centre, Queen's University Belfast, 97 Lisburn Road, Belfast BT9 7BL, Northern Ireland, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bert K.","family":"Rima","sequence":"additional","affiliation":[{"name":"Centre for Infection and Immunity, School of Medicine, Dentistry and Biomedical Sciences, Medical Biology Centre, Queen's University Belfast, 97 Lisburn Road, Belfast BT9 7BL, Northern Ireland, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"W.
