Abstract
Transposons are mobile genetic elements and have been utilized as essential tools in genetics over the years, Though highly useful, many of the current transposon-based applications suffer from various limitations, the most notable of which are: (i) transposition is performed in vivo, typically species specifically, and as a multistep process; (ii) accuracy and/or efficiency of the in vivo or in vitro transposition reaction is not optimal; (iii) a limited set of target sites is used. We describe here a genetic analysis methodology that is based on bacteriophage Mu DNA transposition and circumvents such limitations. The Mu transposon tool is composed of only a few components and utilizes a highly efficient and accurate in vitro DNA transposition reaction with a low stringency of target preference, The utility of the Mu system in functional genetic analysis is demonstrated using restriction analysis and genetic footprinting strategies. The Mu methodology is readily applicable in a variety of current and emerging transposon-based techniques and is expected to generate novel approaches to functional analysis of genes, genomes and proteins.
