轉錄激活域

Most activators have one of these domains.

Some have more than one.

Most of transcription-activating domains fall into three classes:

Acidic domains, such as yeast GAL4 with 11 acidic amino acids out of 49 amino acids in the domain.

Glutamine-rich domains, include Sp1 having 2 such domains that are about 25% glutamine in each.

Proline-rich domains such as CTF which has a domain of 84 amino acids, 19 of which are prolines.
