Using a new promoter analysis transformation vector for Dictyostelium discoideum (PAV-CAT), we have defined cis-acting elements in the promoter of the cyclic AMP-induced early-expressed gene A11H2, which encodes an alpha-fucosidase-related protein (A. Müller-Taubenberger, M. Westphal, A. Noegel, and G. Gerisch, FEBS Lett. 246:185-192, 1989). Sequences responsible for developmentally regulated gene induction could be separated from the basal promoter that conferred low levels of transcriptional activity. By gel shift experiments, we present evidence that the cis-acting element is the target of a trans-acting factor that by itself is subject to developmental regulation.
利用一种用于盘基网柄菌的新型启动子分析转化载体(PAV-CAT),我们确定了环磷酸腺苷诱导的早期表达基因A11H2启动子中的顺式作用元件,该基因编码一种与α-岩藻糖苷酶相关的蛋白质(A. Müller-Taubenberger、M. Westphal、A. Noegel和G. Gerisch,《欧洲生物化学学会联合会快报》246:185 - 192,1989年)。负责发育调控基因诱导的序列可以与赋予低水平转录活性的基础启动子分开。通过凝胶迁移实验,我们提供证据表明顺式作用元件是一种反式作用因子的靶标,而该反式作用因子自身也受发育调控。
