WebbTo qualify as a transcription factor, a protein must possess two qualities. 1) Ability to bind to DNA and 2) recruit RNA polymerase/alter transcription of a gene. Upstream transcription factors are proteins that bind somewhere upstream of the initiation site to stimulate or repress transcription. These are roughly synonymous with specific transcription factors, because they vary considerably depending on what recognition sequences are present in the proximity of the gene. Visa mer In molecular biology, a transcription factor (TF) (or sequence-specific DNA-binding factor) is a protein that controls the rate of transcription of genetic information from DNA to messenger RNA, by binding to a specific Visa mer Transcription 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. Transcription factors use a variety … Visa mer It is common in biology for important processes to have multiple layers of regulation and control.
