Enhancer regions are binding sequences, or sites, for transcription factors. When a DNA-bending protein binds, the shape of the DNA changes (Figure 1). This ...
Like prokaryotic cells, the transcription of genes in eukaryotes requires the actions of an RNA polymerase to bind to a sequence upstream of a gene to initiate transcription. However, unlike prokaryotic cells, the eukaryotic RNA polymerase requires other proteins, or transcription factors, to facilitate transcription initiation. Transcription factors are proteins that bind to the promoter sequence and other regulatory sequences to control the transcription of the target gene. RNA polymerase by itself cannot initiate transcription in eukaryotic cells. Transcription factors must bind to the promoter region first and recruit RNA polymerase to the site for transcription to be established.

Initially, enhancers will keep gene loci in a transcriptionally competent state by sequential recruitment of progressively more lineage-restricted transcription ...
The mammalian genome is packed tightly in the nucleus of the cell. This packing is primarily facilitated by histone proteins and results in an ordered organization of the genome in chromosome territories that can be roughly divided in heterochromatic ...

Genes are organized to make the control of gene expression easier. The promoter region is immediately upstream of the coding sequence. This region can be short (only a few nucleotides in length) or quite long (hundreds of nucleotides long). The longer the promoter, the more available space for proteins to bind. This also adds more control to the transcription process. The length of the promoter is gene-specific and can differ dramatically between genes. Consequently, the level of control of gene expression can also differ quite dramatically between genes. The purpose of the promoter is to bind transcription factors that control the initiation of transcription.

Experiments have shown that TFs can bind tightly, both within cells and in vitro. After TFs bind to promoter or enhancer regions of the DNA, they interact ...
How did eukaryotic organisms become so much more complex than prokaryotic ones, without a whole lot more genes? The answer lies in transcription factors.

Gene expression is a complex process that is essential to living organisms. Gene expression plays the important role of converting information that is encoded in a gene into a functional product. The primary regulators of gene expression are transcription factors (TFs). TFs are proteins that can bind specific DNA sequences and regulate gene expression. Their evolution is influenced by a large number of factors, including epigenetic mechanisms, gene regulatory elements and molecular cofactors. These molecular mediators, along with transcription factors, form a network that governs gene expression. Elucidating the mechanisms through which TFs have evolved and how they influence the evolution of other regulatory molecules can provide information on organism evolution and on the development of phenotypic variations. The aim of this review article was to provide a summary of the current literature on transcription factor evolution, function and how such evolution has played an important role in the emergence of complex organisms.
