转录因子 Transcription factor

(重定向自Transcription factors)
转录因子激活DNA转录

在分子生物学中,转录因子(Transcription factor)是指能够结合在某基因上游特异核苷酸串行上的蛋白质,这些蛋白质能调控其基因的转录。转录因子可以调控核糖核酸聚合酶(RNA聚合酶,或叫RNA合成酶)与DNA模板的结合。转录因子一般有不同的功能区域,如DNA结合结构域与效应结构域。转录因子不单与基因上游的启动子区域结合,也可以和其它转录因子形成转录因子复合体来影响基因的转录。 转录因子是与DNA特异性结合的一系列蛋白质。结合在DNA上的启动子以及增强子之类控制转录的区域上,促进或者抑制DNA上的遗传信息向RNA转录的过程。转录因子的这一机能可以单独,或者通过与其它蛋白质形成复合体来完成。人类的基因组上已经推定出大约1800个基因控制转录因子的编码。

Transcription factor 转录因子

Illustration of an activator
Domain architecture example: Lactose Repressor (LacI).  The N-terminal DNA binding domain (labeled) of the  lac repressor binds its target DNA sequence (gold) in the major groove using a helix-turn-helix motif. Effector molecule binding (green) occurs in the core domain (labeled), a signal sensing domain.  This triggers an allosteric response mediated by the linker region (labeled).

In molecular biology and genetics, a transcription factor (sometimes called a sequence-specific DNA-binding factor) is a protein that binds to specific DNA sequences, thereby controlling the rate of transcription of genetic information from DNA to messenger RNA. Transcription factors perform this function alone or with other proteins in a complex, by promoting (as an activator), or blocking (as a repressor) the recruitment of RNA polymerase (the enzyme that performs the transcription of genetic information from DNA to RNA) to specific genes.
