what is transcription factor
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 bind to either enhancer or promoter regions of DNA adjacent to the genes that they regulate. Depending on the transcription factor, the transcription of the adjacent gene is either up-or down-regulated.
