分离并测序了酵母RNA聚合酶II亚基基因RPB 7,RPB 7是一个单拷贝基因,其序列预测171个氨基酸的19,000道尔顿蛋白。已知RPB 7在体外作为RPB 4/RPB 7亚复合物与RNA聚合酶II解离。RPB 7似乎也以依赖于RPB 4的方式与RNA聚合酶II相互作用,因为从缺乏RPB 4的细胞中纯化的RNA聚合酶II也缺乏RPB 7。先前的结果已经证明,RPB 4的缺失导致生长缓慢以及对冷和温度敏感。相反,RPB 7基因的缺失揭示了它对细胞生长和活力是必不可少的。RPB 4和RPB 7基因的缺失导致致死性。这些结果表明,RPB 7有助于RNA聚合酶II的功能,在RPB 4的情况下,以独立于其与酶的关联的方式或通过直接结合到酶的方式独立于其与RPB 4的关联。
TheSaccharomyces cerevisiaeRNA polymerase II subunit geneRPB7was isolated and sequenced.RPB7is a single copy gene whose sequence predicts a 19,000 Dalton protein of 171 amino acids. RPB7 is known to dissociate from RNA polymerase II as an RPB4/RPB7 subcomplexin vitro. RPB7 also appears to interact with RNA polymerase II in a manner dependent upon RPB4, since RNA polymerase II purified from cells lacking RPB4 also lacks RPB7. Previous results have demonstrated that deletion of theRPB4results in slow growth and cold‐ and temperature‐sensitivity. In contrast, deletion of theRPB7gene revealed that it is essential for cell growth and viability. Loss of both theRPB4and theRPB7genes causes lethality. These results suggest that RPB7 contributes to the function of RNA polymerase II in the absence of RPB4 either in a manner independent of its association with the enzyme or by directly binding to the enzyme in a manner independent of its association with RPB4.
