The sequence includes expression of control elements whose high level of conservation can be seen, i. e. four TATA boxes and one CAAT box.

所得序列含有高度保守的基本表达调控元件，即一个CAAT框和四个TATA框。

Surprisingly, the factor turns out to have been previously characterized as a general repressor of transcription, NC2, an observation explained by its ability to repress TATA-box-containing promoters.

另人吃惊的是，这个因子证明是具有一般转录抑制因子nc2的明显的特征。

Multiprotein bridging factor 1 (MBF1) is a transcriptional co-activator mediating transcriptional activation by bridging between an activator and a TATA-box binding protein (TBP).

MBF1是一个转录辅激活子，通过一个激活物和一个TATA盒结合蛋白的桥连作用来调节转录激活。
