配体与雌激素受体(类固醇受体基因家族的成员)的结合可迅速增加 PRL 基因的转录。大鼠 PRL 基因转录起始位点上游大于 1.5 KB 的 15 碱基对核心序列 5'TTGTCACTATGTCCT-3' 对于受体结合是必需的,证明与受体 DNA 结合结构域的相互作用,并赋予雌激素调节作用。在大鼠PRL雌激素调节元件的调节下,使用编码突变型雌激素受体的表达质粒与荧光素酶报告质粒的瞬时共转染来研究激活基因转录所必需和足够的最少信息。这些分析证实了转录正向调节对受体 DNA 结合结构域的绝对需求,并揭示氨基末端结构域的去除会降低但不会消除转录效应。相反,直接将受体羧基端截断至DNA结合结构域会导致受体的组成型激活。去除类固醇结合结构域会产生组成型活性转录因子,并且氨基末端结构域不是转录作用所必需的,这一观察结果提供了证据,表明对于类固醇受体基因家族的两个成员(糖皮质激素和雌激素受体)来说,相对较短的 DNA 结合结构域足以激活转录。这些结果可能是该转录因子家族其他成员的原型。
Binding of ligand to the estrogen receptor, a member of the steroid receptor gene family, rapidly increases PRL gene transcription. A 15 base pair core sequence 5'TTGTCACTATGTCCT-3' greater than 1.5 kilobase upstream from the rat PRL gene transcription start site is necessary for receptor binding, demonstrates interaction with the receptor DNA binding domain, and confers estrogen regulation. Transient cotransfection of expression plasmids encoding mutant estrogen receptors with a luciferase reporter plasmid under regulation of the rat PRL estrogen regulatory element were used to investigate the minimal information necessary and sufficient for activation of gene transcription. These analyses confirmed the absolute requirement for the receptor DNA binding domain in positive regulation of transcription, and revealed that removal of amino-terminal domains reduced, but did not abolish transcriptional effects. In contrast, truncation of the receptor immediately carboxy-terminal to the DNA binding domain resulted in constitutive activation of the receptor. The observations that removal of the steroid binding domain results in a constitutively active transcriptional factor, and that the amino-terminal domains are not required for transcriptional effect provides evidence that for two members of the steroid receptor gene family (the glucocorticoid and estrogen receptors), a relatively short DNA binding domain is sufficient for transcriptional activation. These results are likely to be prototypic for other members of this family of transcriptional factors.
