Can molecular complementation act as a protein inhibitor?

  1. Dec 5, 2008 #1
    I've always wondered about this. Bimolecular fluorescence complementation allows the incorporation of fragments of the green fluorescent protein (GFP) at the N and C-terminus of separate monomers. If the monomers dimerize, the process allows the GFP fragments to come together and form a functional unit that fluoresces, thereby confirming the existence of specific dimers.

    Is it possible to use the same method to introduce perhaps peptides or fragments of a small protein into separate monomers, whereby the dimerization process allows the formation of a functional unit recognizable by proteases or antibodies to inhibit the activity of the dimer?

    A very interesting and well articulated question. I have no answer and am as curious as you are. :)

    Would it not be easier to simply add a simple tag that can be used to cleave the dimer, once formed?
