Transcription factors are one of the groups of proteins that read and interpret the genetic blueprint in the DNA. They bind to the DNA and help initiate a program of increased or decreased gene transcription. As such, they are vital for many important cellular processes.ranscription factors use a variety of mechanisms for the regulation of gene expression.
