How do eukaryotic activator proteins stimulate the rate of transcription by RNA polymerase II?
A large number of activator proteins have now been identified in higher and lower eukaryotes, which bind to the regulatory regions of protein-encoding genes and increase the rate at which they are transcribed by RNA polymerase II. The mechanism by which activators function is being intensively studied and some of the targets of transcriptional activation domains have now been identified. These studies have also revealed novel classes of regulatory factors, which were not anticipated by extrapolating from the principles obtained with prokaryotic promoters.
