Abstract
By combining custom zinc finger (ZF) DNA-binding technology [1,2] with protein fragment complementation [3], we have developed a technology, designated SEER (Sequence-Enabled Reassembly), that has the potential to “see” or detect genetic information within a living cell (Figure 1). These agents consist of two inactive parts of signal-generating peptides that have the ability to recognize specific DNA sequences. The two parts bind near each other in the presence of a user-defined DNA target site and generate a fluorescent signal. Two prototype SEER systems have been constructed, based on the reassembly of green fluorescent protein (SEERGFP) [4] and the enzyme β-lactamase (SEER-LAC). To our knowledge, these are the first examples of DNA-dependent reassembly of peptide fragments.
