Abstract
The present invention describes a method for detecting biomolecular interactions said method comprising: (a) selecting an appropriate reporter molecule selected from the group consisting of a protein, a fluorescent protein, a luminescent protein and a phosphorescent protein; (b) effecting fragmentation of said reporter molecule such that said fragmentation results in reversible loss of reporter function; (c) fusing or attaching fragments of said reporter molecule separately to other molecules; followed by (d) reassociation of said reporter fragments through interactions of the molecules that are fused to said fragments; and (e) detecting said biomolecular interactions by reconstitution of activity of the reporter molecule with the proviso that said protein is not ubiquitin.
