Phage display has been used to engineer DNA-binding proteins with new sequence specificities, which has allowed applications in the blockage or enhancement of gene expression as well as targeting specific sites on DNA for methylation, recombination, and cleavage. To effectively and quickly conduct selections that consider the synergistic mode of DNA binding by zinc fingers, Isalan and Choo in Aaron Klug's lab devised a bipartite phage display approach that enables selection and recombination of variants of zinc finger DNA-binding domains from a pair of premade complementary phage libraries for any given 9-bp DNA sequence. The bipartite phage display has the advantage of rapid, high-throughput selection of sequence-specific zinc finger DNA-binding domains for use in diverse applications of expression control and gene targeting. © 2010 Springer Science+Business Media, LLC.
