Deletion of a DNA polymerase beta gene segment in T cells using cell type-specific gene targeting

Science. 1994 Jul 1;265(5168):103-6. doi: 10.1126/science.8016642.

Abstract

Deletion of the promoter and the first exon of the DNA polymerase beta gene (pol beta) in the mouse germ line results in a lethal phenotype. With the use of the bacteriophage-derived, site-specific recombinase Cre in a transgenic approach, the same mutation can be selectively introduced into a particular cellular compartment-in this case, T cells. The impact of the mutation on those cells can then be analyzed because the mutant animals are viable.
