ResultsGene Activation by the Antp Protein Several Drosophila promoters were screened for possible regulation by the Antp protein. The five promoters that were tested in this study were the Ubx promoter (Hogness et al., 1985; Saari and Bienz, 1987; Kornfeld et al., 1989) the two Antp promoters (Schneuwly et al., 1986; Stroeher et al., 1986; Laughon et al., 1986) the hsp70 promoter (Karch et al., 1981), and the copia transposon promoter (Sinclair et al., 1988). Each of the reporter plasmids used contains a promoter fragment joined to the E. coli chloramphenicol acetyl transferase (CAT) gene (Figure la; Thummel et al., 1988; Krasnow et al., 1989). The plasmids were transfected into Drosophila Schneider Line 2 (S2) cells (Schneider, 1972), and CAT activity was assayed 48-60 hr later. All of the tested promoters were detectably active in these transient assays (data not shown; Krasnow et al., 1989).To determine whether Antp protein can affect transcription from any of the candidate target promoters, a plasmid was constructed that directs expression of an Antp protein (Figure lb). In this plasmid, the Drosophila acfin 5C promoter (Bond and Davidson, 1986) was joined to the Antp cDNA GllOO (Laughon et al., 1986). actin 5C is active in most or all Drosophila cells. The Antp protein-expression plasmid contains the entire Antp protein-coding sequence as well as 253 bp of the 5’nontranslated region, part of the 3’trailer sequence, and actin 5C polyadenyla-
