Interaction of C-terminal deletion mutants of p51 with lexA₂₀₂-Ala-66. p51 domains were fused to the C terminus of the Gal4AD in pACTII. Deletions at the C terminus are denoted by the number of amino acids missing from the end of p51. β-gal activity was determined as described in the legend of Fig. 2. Expression of p51 fusion proteins in CTY10-5d was detected by using anti-GAL4AD antibodies, and expression levels are as denoted in the legend for Fig. 1.
