VCre/VloxP and SCre/SloxP: New Site-Specific Recombination Systems for Genome Engineering

Nucleic Acids Res. 2011 Apr;39(8):e49. doi: 10.1093/nar/gkq1280. Epub 2011 Feb 1.

Abstract

We developed two new site-specific recombination systems named VCre/VloxP and SCre/SloxP for genome engineering. Their recognition sites are different from Cre recognition sites because VCre and SCre recombinases share less protein similarity with Cre, even though the basic 13-8-13 structures of their recognition sites are identical. Mutant VloxP and SloxP, which have the same uses as mutant loxP, were also developed. VCre/VloxP and SCre/SloxP in combination with Cre/loxP and Flp/FRT systems can serve as powerful tools for genome engineering, especially when used to genetically modify both alleles of a single gene in mouse and human cells.
