This composite part is a "lock" designed to prevent expression of a downstream gene unless a specific sequence of recombination events occurs to the part. Specifically, successive application of the Hin and Cre recombinases, respectively, will "unlock" the part leading to constitutive expression of the downstream gene(s). It was refered to as the "Lock Cassette" or "Lock Construct" by the [http://2010.igem.org/Team:Wisconsin-Madison Wisconsin-Madison 2010] iGEM team.

It can be used in conjunction with the Key Cassette after miscellaneous (junk) DNA is added to either the HindIII or the SapI (5' ATC 3' overhang) sites that are located within the part. According to the literature, it is necessary to have approximately 900 base pairs of DNA within the recombination sites for optimal recombination. As of October 2010, we were unable to characterize how the length of junk DNA affects the rates of recombination of the construct.
