人类 T 细胞白血病病毒 I 型 (HTLV-I) p40x 蛋白是在病毒 3' 末端区域编码的 40 千道尔顿多肽。该蛋白负责位于 HTLV-I 长末端重复序列内的启动子元件的正转录反式激活。我们将 HTLV-I p40x 的蛋白质编码区引入杆状病毒苜蓿银纹夜蛾核型多角体病毒的基因组中。感染昆虫草地贪夜蛾 (SF9) 细胞系后,这种杆状病毒重组菌株每 2.5 X 10(8) 细胞产生约 200 毫克完整的 p40x 蛋白。该蛋白质在HTLV-I长末端重复-人β-珠蛋白构建体的反式激活中具有生物活性。该蛋白质的生化分析表明,p40x 多肽在这些真核 SF9 细胞中经历了翻译后修饰。
The human T-cell leukemia virus type I (HTLV-I) p40x protein is a 40-kilodalton polypeptide encoded in the 3'-terminal region of the virus. This protein is responsible for positive transcriptional trans-activation of promoter elements located within the HTLV-I long terminal repeat. We introduced the protein-coding region of HTLV-I p40x into the genome of the baculovirus Autographa californica nuclear polyhedrosis virus. After infection of the insect Spodoptera frugiperda (SF9) cell line, this recombinant strain of baculovirus produced approximately 200 mg of intact p40x protein per 2.5 X 10(8) cells. The protein was biologically active in trans-activation of an HTLV-I long terminal repeat-human beta-globin construct. Biochemical analyses of the protein suggest that the p40x polypeptide underwent posttranslational modification in these eucaryotic SF9 cells.
