transcription.

The activity of activators can be regulated. Some activators have an allosteric site and can only function when a certain molecule binds to this site, essentially turning the activator on. Post-translational modifications to activators can also regulate activity, increasing or decreasing activity depending on the type of modification and activator being modified.

In some cells, usually eukaryotes, multiple activators can bind to the binding-site; these activators tend
