结果筛选出几个果蝇启动子可能受ANTP蛋白调控。在本研究中测试的五个启动子是Ubx启动子(Hogness等人,1985;Saari和Bienz,1987;Kornfeld等人,1989)、两个ANTP启动子(Schneuwly等人,1986;Stroeher等人,1986;Laughon等人,1986)、HSP70启动子(Kch等人,1981)和Copia转座子启动子(Sclair等人,1988)。使用的每个报告质粒都包含一个连接到大肠杆菌氯霉素乙酰转移酶(CAT)基因的启动子片段(图1a;Thummel等人,1988年;Krasnow等人,)。将其导入果蝇Schneider Line2(S2)细胞,48-60小时后检测CAT活性。所有测试的启动子在这些瞬时检测中都具有活性(数据未显示;Krasnow等人,1989)。为了确定ANTP蛋白是否可以影响任何候选目标启动子的转录,构建了指导ANTP蛋白表达的质粒(图1b)。在该质粒中,果蝇acfin 5C启动子(Bond和Davidson,1986)连接到ANTP cDNAGl100(Laughon等人,1986)。肌动蛋白5C在大多数或所有果蝇细胞中都是活跃的。ANTP蛋白表达载体含有完整的ANTP蛋白编码序列,以及5‘非翻译区的253bp,3’末端序列的一部分,以及肌动蛋白5C多聚腺苷。
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-
