Some kinds of transcription factor proteins are very important in initiating and guiding cell fate differentiation. Overexpression of these factors can force many other kinds of cells to become muscle or nerve. Examples are MyoD for muscle and Ascl1 for nerve. It is not known how long such a factor must remain bound to its binding site for it to have its function; this could be seconds

Activating transcription factor, ATF, is a group of bZIP transcription factors, which act as homodimers or heterodimers with a range of other bZIP factors. First, they have been described as members of the CREB/ATF family, [2] whereas it turned out later that some of them might be more similar to AP-1 -like factors such as c-Jun or c-Fos . [3]

Therefore, they can be either activators that turn “on” the gene expression or repressors that turn “off” the gene expression. 2021-04-17 · In transcription factor. Basal, or general, transcription factors are necessary for RNA polymerase to function at a site of transcription in eukaryotes. They are considered the most basic set of proteins needed to activate gene transcription, and they include a number of proteins, such as TFIIA (transcription factor… Other transcription factors, such as SOX17, Brachyury, and Pax6, are capable of driving the differentiation of pluripotent stem cells into endoderm, mesoderm, and ectoderm, respectively. A better understanding of the transcription factors that regulate ES cell differentiation may inform the generation of clinically relevant cell types from iPS cells. 2001-04-27 · Transcription factor that can activate or repress transcription in response to physiological and pathological stimuli. Binds with high affinity to GC-rich motifs and regulates the expression of a large number of genes involved in a variety of processes such as cell growth, apoptosis, differentiation and immune responses.

In this work, we identify and characterize BarR, a novel Lrp-like transcription factor and the first one that has a non-proteinogenic amino acid 

More detailed information is found in the manuscript and the web site accompanying the paper (Human Transcription Factors) List of human transcription factors (1639) 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. so what makes the cell that's located inside of your nose responsible for smelling say a slice of pizza look and act differently from a cell that lines your gut and is responsible for absorbing the nutrients from that pizza they have the exact same DNA so the differences can't be attributed to that fact alone the answer actually lies in the expression of that DNA which genes are actively Transcription factors determine when genes will be turned on and turned off, orchestrating the many processes involved in the development of an embryo and the many tasks performed by each cell after a child is born.
