Negative regulatory element and its binding protein of hepatitis B virus
博士 === 國立陽明大學 === 微生物及免疫學研究所 === 85 === B型肝炎病毒的複製及基因表現具有組織特異性,這種特異性主要是受到多重轉錄調控序列及具有組織特異性之轉錄蛋白的控制。已知B型肝炎病毒的基因群中包含了四個起動子及兩個具有組織特異性的加強子。其中第二加強子(核甘酸序列1636至1741),簡稱ENII位於核心抗原起動子的上游,它可以加強表面抗原起動子(SPI),X蛋白起動子及異源性起動子(如SV40早期起動子)的轉錄活性,同時其加強能力與距離及方向性無關,因此其作用方式為加強子模式。但是同樣這段序列只能以正向且位於上游方式增強核心抗原起動子的轉錄,所以作用方式為上游調控...
