Abstract:
Effective genome engineering should lead to a desired locus change with minimal adverse impact to the genome itself. However, flanking loci with site-directed recombinase recognition sites, such as those of the phage ΦC31 integrase, allows for creation of platforms for cassette exchange and manipulation of genomic regions in an iterative manner, once specific loci have been targeted. Here we show that a genomic locus engineered with inverted minimal phage ΦC31 attP/attB sites can undergo efficient recombinase-mediated cassette exchange (RMCE) in the fruit fly Drosophila melanogaster.

Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...
