我们研究了TFIIH在RNA聚合酶II(波尔II)在体内转录的作用,通过显微注射针对该因子的抗体到非洲爪蟾卵母细胞。针对TFIIH的四个亚基的五种不同的抗体被测试对共注射的人类免疫缺陷病毒2型和c-myc模板的转录的影响。这些抗体中的每一种都严重降低了通过人类免疫缺陷病毒2型和c-myc终止子元件延伸的效率。相反,抗TFIIB抗体不抑制延伸。抗TFIIH抗体对总转录的抑制作用也比抗TFIIB或抗pol II大亚基小得多。TFIIH激酶活性的三种抑制剂H-7、H-8和二氯呋喃核糖基苯并咪唑(DRB)与抗TFIIH抗体类似地抑制延伸。这些结果强烈表明TFIIH在体内刺激转录延伸中的作用。
We investigated the role of TFIIH in transcription by RNA polymerase II (pol II) in vivo by microinjection of antibodies against this factor into Xenopus oocytes. Five different antibodies directed against four subunits of TFIIH were tested for effects on transcription of coinjected human immunodeficiency virus type 2 and c-myc templates. Each of these antibodies severely reduced the efficiency of elongation through human immunodeficiency virus type 2 and c-myc terminator elements. In contrast, an anti-TFIIB antibody did not inhibit elongation. Anti-TFIIH antibodies also had a much smaller inhibitory effect on total transcription than did anti-TFIIB or anti-pol II large subunit. Three inhibitors of TFIIH kinase activity, H-7, H-8, and dichlororibofuranosylbenzimidazole (DRB), inhibited elongation similarly to anti-TFIIH antibodies. These results strongly suggest a role for TFIIH in the stimulation of transcriptional elongation in vivo.
