Title: Paramyxoviruses having modified transcription initiation sequence
IPC: C12N15/86
Filed: 2000-09-06
Abstract: The present invention provides virus vectors of the family Paramyxoviridae in which the transcription start (S) sequence has been modified so as to modify the expression of genes located downstream thereof, a method for producing the vectors, and uses thereof. By measuring the transcription initiation efficiency of the S sequence of each gene carried by Sendai viruses (SeV), it was clarified that the S sequence of F gene has a significantly lower ability to promote transcription than the other three S sequences. When the S sequence of the F gene of wild type Sendai virus was substituted by the S sequence of the P/M/HN gene-type showing a high transcription initiation efficiency, the F gene of the resultant Sendai virus mutant and genes located downstream thereof show elevated expression levels. It was also revealed that this mutant proliferates more quickly than the wild type. The vectors of this invention are useful in elevating the expression of foreign genes and producing pharmaceutical compositions and vaccines.
