In fact, many regulatory systems in biology are basically logical circuits built out of biomolecules. In general, this is a pretty good takeaway. In Developmental biology 6th ed. Expression of a large family of POU-domain regulatory genes in mammalian brain development. A well studied example of this are the transcription-activator like effectors TAL effectors secreted by Xanthomonas bacteria.

The HOX family are involved in a variety of cancers. The c-erb-A protein is a high-affinity receptor for thyroid hormone. Additional recognition specificity, however, may be obtained through the use of more than one DNA-binding domain for example tandem DBDs in the same transcription factor or through dimerization of two transcription factors that bind to two or more adjacent sequences of DNA.

Transcription factor – Wikipedia

Do you have any transcription factors in your body? Cloning and expression of AP-2, a cell-type-specific transcription factor that activates inducible enhancer elements. TFs work alone or with other proteins in a complex, by promoting as an activatoror 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. There are up to TFs in the human genome. In code, this might look something like:.
