Abstract Background Maps depicting binary interactions between proteins can be powerful starting points for understanding biological systems. A proven technology for generating such maps is high-throughput yeast two-hybrid screening. In the most extensive screen to date a Gal4-based two-hybrid system was used recently to detect over 20 000 interactions among Drosophila proteins. Although these data are a valuable resource for insights into protein networks they cover only a fraction of the expected number of interactions. Results To complement the Gal4-based interaction data we used the same set of Drosophila open reading frames to construct arrays for a LexA-based two-hybrid system. We screened the arrays using a novel pooled mating approach initially focusing on proteins related to cell-cycle regulators. .
