在真核细胞中,TATA 结合蛋白 (TBP) 与称为 TBP 相关因子 (TAF) 的其他蛋白质结合,形成对所有三种核 RNA 聚合酶的基因表达都很重要的多亚基转录因子。对完整酿酒酵母基因组的计算机搜索揭示了 5 个以前未识别的酵母基因,它们与已知的人类和果蝇 RNA 聚合酶 II TAF 具有显着的序列相似性。这些基因中的每一个对于生存都是必需的。先前已注意到第六个必需基因 (FUN81) 与人类 TAFII18 相似。免疫共沉淀实验表明,所有六种蛋白质均与 TBP 相关,证明它们是真正的 TAF。此外,这些蛋白质存在于含有 TAFII130 亚基的复合物中,表明它们是 TFIID 的组成部分。根据预测的分子量,这些基因被命名为 TAF67、TAF61(68)、TAF40、TAF23(25)、TAF19(FUN81) 和 TAF17。 酵母 TAF61 明显大于其高等真核同源物,缺失分析表明,进化上保守的组蛋白样结构域对于支持活力来说是充分且必要的。
In eukaryotic cells the TATA-binding protein (TBP) associates with other proteins known as TBP-associated factors (TAFs) to form multisubunit transcription factors important for gene expression by all three nuclear RNA polymerases. Computer searching of the completeSaccharomyces cerevisiaegenome revealed five previously unidentified yeast genes with significant sequence similarity to known human andDrosophilaRNA polymerase II TAFs. Each of these genes is essential for viability. A sixth essential gene (FUN81) has previously been noted to be similar to human TAFII18. Coimmunoprecipitation experiments show that all six proteins are associated with TBP, demonstrating that they are true TAFs. Furthermore, these proteins are present in complexes containing the TAFII130 subunit, indicating that they are components of TFIID. Based on their predicted molecular weights, these genes have been designatedTAF67,TAF61(68),TAF40,TAF23(25),TAF19(FUN81), andTAF17. Yeast TAF61 is significantly larger than its higher eukaryotic homologues, and deletion analysis demonstrates that the evolutionarily conserved, histone-like domain is sufficient and necessary to support viability.
