Amongst members of the ETS family, there is extensive conservation in the DNA-binding ETS domain and, therefore, a lot of redundancy in DNA binding. It is thought that interactions with other proteins (eg: Modulator of the activity of Ets called Mae) is one way in which specific binding to DNA is achieved. Transcriptio... | 1 | Biochemistry |
