Abstract: Modified Morbilliviruses having at least one mutation in the region corresponding to amino acids 112-134 of the measles virus V protein are described, wherein one or both of amino acids 113 or 114 is mutated. Such modified Morbilliviruses exhibit reduced repression of gene expression. Additional mutations or deletions in other regions of the genome may be included, including in the carboxy-terminal region.

Abstract: This invention relates to improved methods for producing nonsegmented, negative-sense, single-stranded RNA viruses of the Order designated Mononegavirales virus, including embodiments relating to methods of producing such viruses as attenuated and/or infectious viruses, such as Measles virus (MV) and respiratory syncytial virus (RSV).

Abstract: Multiple binding sites for the transcription factors MAZ and Sp1 within the adenovirus type 5 major late promoter have been identified by DNase I protection studies. In the proximal region of the promoter, both MAZ and Sp1 interact with GC-rich sequences flanking the TATA box. Two MAZ binding sites are centered at −18 and −36 relative to the transcriptional initiation site. Sp1 bound only to the −18 GC-rich sequence. Several sites of interaction were also evident in the distal region of the promoter. Both MAZ and Sp1 interacted with a sequence centered at −166, and MAZ bound weakly to an additional site centered at −130. Over expression of MAZ or Sp1 activated expression from the major late promoter in transient expression assays.
