This protocol describes using the Gateway recombinatorial cloning system to create an Entry clone carrying an open reading frame (ORF) and then to transfer the ORF into a Destination vector. In this example, BP recombination is used to clone an ORF from a cDNA source into the Donor vector pDONR 221. The ORF from the resulting Entry clone is then transferred into the Destination vector pDEST-15; the product (the Destination clone) will express the ORF as an amino-terminal GST-fusion. The technique can be used as a guide for cloning any other DNA fragment of interest-a promoter sequence or 3' untranslated region (UTR), for example-with substitutions of different genetic material such as genomic DNA, att sites, and vectors as required. The series of constructions and transformations requires 9-15 d, not including time that may be required for sequence confirmation, if desired/necessary.
