为了探明中国明对虾卵黄蛋白原基因启动子表达调控机制,利用DNA步移法克隆了中国明对虾卵黄蛋白原基因启动子及其上游调控序列,总长1 100bp.分析表明,在基因转录起始位点上游-30~-24bp处有1个TATA box,未发现有CAAT box和GC box.同时,在上游调控区还存在有多个可能影响启动子转录活性的顺式作用元件,如NF-κB,YY1和SP1等转录因子结合位点.这些结果为深入研究中国明对虾卵黄蛋白积累及卵子发生过程奠定了基础. 相似文献

Cloning and structure of a yeast gene encoding a general transcription initiation factor TFIID that binds to the TATA box 总被引:75,自引:0,他引:75
The TATA sequence-binding factor TFIID plays a central role both in promoter activation by RNA polymerase II and other common initiation factors, and in promoter regulation by gene-specific factors. The sequence of yeast TFIID, which seems to be encoded by a single gene, contains interesting structural motifs that are possibly involved in these functions, and is similar to sequences of bacterial sigma factors. 相似文献
