人K14角蛋白基因的启动子是层状上皮基底层特异性的,受视黄酸和甲状腺激素的核受体调控。然而,负责这种调节的DNA序列尚未被确定。为了确定维甲酸反应位点,我们设计了一种简单的位点特异性诱变方法,并将突变引入K14角蛋白基因启动子。这些突变确定了维甲酸反应位点。该站点由一组不同方向的共识回文半站点组成。如前所述,视黄酸和甲状腺激素受体可以识别和结合受调控基因中的共同序列。在这里,我们描述了取消两个受体调节的突变。有趣的是,甲状腺激素核受体的激素依赖性和独立调节位点可以分开。在K5和K10角蛋白基因启动子中发现了与K14调控位点共享结构组织的半位点簇。类似的簇可能负责维甲酸介导的表皮转录调节。
The promoter of human K14 keratin gene, specific for the basal layer of stratified epithelia, is regulated by nuclear receptors for retinoic acid and thyroid hormone. However, the DNA sequences responsible for this regulation have not yet been identified. To identify the retinoic acid-responsive site, we have devised a simple site-specific mutagenesis method and introduced mutations into the K14 keratin gene promoter. These mutations identify the retinoic acid-responsive site. The site consists of a cluster of consensus palindrome half-sites in various orientations. As shown previously, retinoic acid and thyroid hormone receptors can recognize and bind common sequences in regulated genes. Here, we describe mutations that abolish regulation by both receptors. Interestingly, the hormone-dependent and-independent regulatory sites of the thyroid hormone nuclear receptor can be separated. Clusters of half-sites that share structural organization with the K14 regulatory site were found in the K5 and K10 keratin gene promoters. Similar clusters may be responsible for retinoic acid-mediated transcription regulation in epidermis.
