Site-specific integration with bacteriophage ΦC31 integrase.
Few nonviral techniques exist for efficient and stable eukaryotic gene transfer and fewer still are broadly useful in both cell culture and whole-organism applications. C31 integrase, a site-specific bacteriophage recombinase, is able to catalyze chromosomal transgene insertion under a diverse range of experimental and therapeutic conditions. The enzyme recognizes and catalyzes unidirectional r...
متن کاملTargets for pSAM2 integrase-mediated site-specific integration in the Mycobacterium smegmatis chromosome.
An improved integrative cassette from plasmid pSAM2 has been constructed containing plasmid int and attP genes but excluding the xis gene, which should results in increased stability by suppression of the excision reaction. This cassette was included in both suicide and thermosensitive plasmids and used for integration in Mycobacterium smegmatis. Suicide plasmids containing this cassette integr...
متن کاملTargeting site-specific chromosome integration.
The concept of gene therapy was introduced with great promise and high expectations. However, what appeared simple in theory has not translated into practice. Despite some success in clinical trials, the research community is still facing an old problem: namely, the need for a vector that can deliver a gene to target cells without adverse events while maintaining a long-term therapeutic effect....
متن کاملIdentification of a Specific Pseudo attP Site for Phage PhiC31 Integrase in Bovine Genome
Background: PhiC31 integrase system provides a new platform in various felid of research, mainly in gene therapy and creation of transgenic animals. This system enables integration of exogenous DNA into preferred locations in mammalian genomes, which results in robust, long-term expression of the integrated transgene. Objectives: Identification of a novel pseudo attP site. Materials and Methods...
متن کاملA phage integrase directs efficient site-specific integration in human cells.
The integrase from the Streptomyces phage phiC31 carries out efficient recombination between the attP site in the phage genome and the attB site in the host bacterial chromosome. In this paper, we show that the enzyme also functions in human cells. A plasmid assay system was constructed that measured intramolecular integration of attP into attB. This assay was used to demonstrate that in the pr...
