A differential response element for the homeotics at the Antennapedia P1 promoter of Drosophila. Proc. Natl. Acad. Sci. USA 91, 7420-7424 .pdf
... The distinct developmental functions of the homeoproteins presumably result from differences in target gene regulation: either they regulate different target genes or they regulate the same target genes differently. Such regulatory differences could be due to use of different regulatory elements (ta ...
