In eukaryotes, transcriptional regulators are not typically controlled at the level of DNA binding (although there are exceptions). Regulators are instead usually controlled in one of the following two basic ways.

I. Unmasking an Activating Region

II. Transport into and out of the Nucleus

III. Mediated through proteolysis of an inhibitor or tethering region or by allosteric changes.

IV. Also is itself (or recruits) a deacetylase,
