In trznscription respect, a single-copy transcription factor can undergo a change of specificity through a promiscuous intermediate without losing function. Gene regulation by steroid hormones. Both activators are present, but the repressor is also present.

Eukaryotic transcription factors.

Both activators are present, the repressor is absent. Trabscription date values in: In fact, many regulatory systems in biology are basically logical circuits built out of biomolecules.


For instance, many different transcription factors may be involved, or it may matter exactly how many molecules of a given transcription factor are bound to the DNA. Biochem Biophys Res Commun. DNA binding by proteins.

Regulation of neuronal gene expression by the neuron-restrictive silencer. Not only do transcription factors act downstream of signaling cascades related to biological stimuli but they can also be downstream of signaling cascades involved in environmental stimuli.

In eukaryotesan important class of transcription factors called general transcription factors GTFs are necessary for transcription to occur.

Annual Review of Genetics. Carroll Endless Forms Most Beautiful. Enhancers like those of the Tbx4 gene are called tissue-specific transxription Once they occur as duplicates, accumulated mutations encoding for one copy can take place without negatively affecting the regulation of downstream targets.
