Transcription factors are proteins that control the transfer of information from the DNA sequence to mRNA by binding to a specific DNA sequence. These proteins interact with the accelerator group by binding to the enhancer and accelerator regions. These proteins, which are grouped according to their structural similarities, are DNA-specific proteins because they bind to different DNA sequences according to the differences in their structures [1]. This website has covered the Basic Helix-Loop-Helix DNA-binding transcription factors.
