Site-specific DNA recombination in mammalian cells by the Cre recombinase of bacteriophage P1.
The Cre protein encoded by the coliphage P1 is a 38-kDa protein that efficiently promotes both intra- and intermolecular synapsis and recombination of DNA both in Escherichia coli and in vitro. Recombination occurs at a specific site, called lox, and does not require any other protein factors. The Cre protein is shown here also to be able to cause synapsis of DNA and site-specific recombination...
متن کاملBacteriophage P 1 Site - specific Recombination PURIFICATION AND PROPERTIES OF
Bacteriophage P1 encodes a site-specific recombination system that consists of a site (loxP) at which recombination occurs and a gene, ere, whose protein product is essential for recombination. The loxP-Cre recombination event can be studied in greater detail by the use of an in vitro system that efficiently carries out recombination between two loxP sites. This paper presents a purification an...
متن کاملCre recombinase-mediated site-specific recombination between plant chromosomes.
We report the use of the bacteriophage P1 Cre-lox system for generating conservative site-specific recombination between tobacco chromosomes. Two constructs, one containing a promoterless hygromycin-resistance gene preceded by a lox site (lox-hpt) and the other containing a cauliflower mosaic virus 35S promoter linked to a lox sequence and the cre coding region (35S-lox-cre), were introduced se...
متن کاملPepA and ArgR do not regulate Cre recombination at the bacteriophage P1 loxP site
In the lysogenic state, bacteriophage P1 is maintained as a low copy-number circular plasmid. Site-specific recombination at loxP by the phage-encoded Cre protein keeps P1 monomeric, thus helping to ensure stable plasmid inheritance. Two Escherichia coli DNA-binding proteins, PepA and ArgR, were recently reported to be necessary for maintenance or establishment of P1 lysogeny. PepA and ArgR bin...
متن کاملMicroinjection of cre recombinase RNA induces site-specific recombination of a transgene in mouse oocytes.
We have developed a strategy for producing single copy transgenic mouse lines using Cre-loxP site specific recombination. The method is based on transient expression of the recombinase after injection of in vitro transcribed mRNA into the cytoplasm of fertilised eggs containing multiple copies of the transgene. The success rate of the recombination event is 100% (15 out of 15).
