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 کاملTrapping of mammalian promoters by Cre-lox site-specific recombination.
One of the challenges in human genome research is to identify the promoter sequences which play a key role in the regulation of gene expression. We report here a new promoter trapping system for use with mammalian cells comprised of the following three steps: 1) Cloning of DNA fragments into a promotertrapping vector, 2) integration of the trapping vector into a designated target in the mammali...
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 کاملEfficient gene activation in mammalian cells by using recombinant adenovirus expressing site-specific Cre recombinase.
A recombinant adenovirus (Ad) expressing Cre recombinase derived from bacteriophage P1 was constructed. To assay the Cre activity in mammalian cells, another recombinant Ad bearing an on/off-switching reporter unit, where a LacZ-expression unit can be activated by the Cre-mediated excisional deletion of an interposed stuffer DNA, was also constructed. Co-infection experiments together with the ...
متن کاملNuclear targeting determinants of the phage P1 cre DNA recombinase.
The Cre DNA recombinase of bacteriophage P1 has become a useful tool for genomic manipulation in mice and other eukaryotes. Because Cre is of prokaryotic origin, the 38 kDa protein has been presumed to gain access to the eukaryotic nucleus simply because it is sufficiently small to pass through the nuclear pore by passive diffusion. Instead, we show here that Cre carries nuclear targeting deter...
