The Fiber Disease

... seems to mediate the binding to specific DNA sequences, whereby the homeotic proteins exert a gene regulatory function. By isolating the normal Antennapedia gene, fusing its protein-coding sequences to an inducible promoter, and reintroducing this fusion gene into the germline of flies, it has ...
