因为它在体外只有这个反式激活的活性。那你下调要改变它活性？

In the context of gene regulation: transactivation is the increased rate of gene expression triggered either by biological processes or by artificial means, through the expression of an intermediate transactivator protein.

看看你是否理解错了这个词。

果然我理解错了transactivation这个词！太谢谢你了！我一直以为是反式作用元件。它的正确中文翻译是什么呢？
...

4楼说的好，学习了，另外这个词你怎么翻译没定义吧？你叫它反式激活，只要你理解反式激活是干什么用就好了。

In the field of molecular biology, trans-acting (trans-regulatory, trans-regulation), in general, means "acting from a different molecule" (i.e., intermolecular). It may be considered the opposite of cis-acting (cis-regulatory, cis-regulation), which, in general, means "acting from the same molecule" (i.e., intramolecular).
