2017-05-24 · Transcription factors bind to the regulatory elements of the promotor region. During gene activation, transcription factors also bind to the enhancer regions, forming a loop that recruits RNA polymerase II in order to initiate the transcription. Repressors block general transcription factors to the regulatory elements of DNA. Reference: 1.

They are usually proteins, although they can also consist of short, non-coding RNA. TFs are also usually found working in groups or complexes, forming multiple interactions that allow for varying degrees of control over rates of transcription. Transcription factors are a common way in which cells respond to extracellular information, such as environmental stimuli and signals from other cells. Transcription factors can have important roles in cancer, if they influence the activity of genes involved in the cell cycle (or cell division cycle). Transcription factors (TFs) recognize specific DNA sequences to control chromatin and transcription, forming a complex system that guides expression of the genome.

Transcription factors act within larger multiprotein complexes. In the setting of hematopoiesis, transcription factors often act positively to sustain their own expression, while simultaneously acting to cross-regulate other transcription factors, thereby establishing complex transcriptional networks.

In Eukaryotes, transcription factors, rather than the enzymes themselves, are principally responsible for recognizing the promoter. Transcription factors are able to bind to specific sets of short conserved sequences contained in each promoter. Transcription factors (TFs) recognize specific DNA sequences to control chromatin and transcription, forming a complex system that guides expression of the genome. Despite keen interest in understanding how TFs control gene expression, it remains challenging to determine how the precise genomic binding sites of TFs are specified and how TF binding ultimately relates to regulation of transcription.

In molecular biology, a transcription factor is a protein that controls the rate of transcription of genetic information from DNA to messenger RNA, by binding to a

Transcription factors can do This list of manually curated human transcription factors is taken from Lambert, Jolma, Campitelli et al. It was assembled by manual curation.

Binds DNA cooperatively with E2F family members through the E2 recognition site, 5'-TTTC[CG]CGC-3', found in the promoter region of a number of genes whose products are involved in cell cycle regulation or in DNA replication (PubMed:8405995, PubMed:7739537). Light-inducible gene switches represent a key strategy for the precise manipulation of cellular events in fundamental and applied research.
