7.5B: The Promoter and the Transcription Machinery

(Just Now) Transcription factors recognize the promoter. RNA polymerase II then binds and forms the transcription initiation complex. Within the promoter region, just upstream of the transcriptional start site, resides the TATA box. This box is simply a repeat of thymine and adenine dinucleotides (literally, TATA repeats).

FAQ?

What are some examples of transcription factors?

Many transcription factors, especially some that are proto-oncogenes or tumor suppressors, help regulate the cell cycle and as such determine how large a cell will get and when it can divide into two daughter cells. One example is the Myc oncogene, which has important roles in cell growth and apoptosis.

What do transcription factors bind to?

Transcription factors bind to either enhancer or promoter regions of DNA adjacent to the genes that they regulate. Depending on the transcription factor, the transcription of the adjacent gene is either up- or down-regulated. Transcription factors use a variety of mechanisms for the regulation of gene expression.

How do transcription factors work?

How Do Transcription Factors Work. Transcription factors are proteins that bind to DNA in order to regulate the gene expression by promoting or suppressing gene expression. Therefore, they can be either activators that turn “on” the gene expression or repressors that turn “off” the gene expression.

Where are transcription factors located?

In eukaryotes, transcription factors (like most proteins) are transcribed in the nucleus but are then translated in the cell's cytoplasm. Many proteins that are active in the nucleus contain nuclear localization signals that direct them to the nucleus.
