DNA damage or UV irradiation leads to induction of synthesis of the BH3-only Puma protein which binds to Bak and Bax as well as to Bcl-2, allowing Bak and

Bax to form oligomeric pores.

An additional DNA element that binds RNA polymerase is found in some strong promoters, for example, those directing expression of the ribosomal RNA (rRNA) genes. This is called an UP-element and increases polymerase binding by providing an additional specific interaction between the enzyme and the DNA.
