  • Title: A novel modulator domain of Ets transcription factors.
    Author: Wasylyk C, Kerckaert JP, Wasylyk B.
    Journal: Genes Dev; 1992 Jun; 6(6):965-74. PubMed ID: 1592263.
    Abstract:
    The ets gene family is composed of several oncogenes and codes for transcription factors. The Ets proteins have a similar sequence called the ets domain and bind to the core motif A/CGGAA. We show here that several members of the ets family have different trans-activating properties. The ets domain of Ets-1 is required for DNA binding. Adjacent to this domain there is a novel element that inhibits DNA binding. It appears to alter the structure of the DNA-binding domain before it interacts with DNA. There is a similar sequence in Ets-2 that also inhibits DNA binding. This sequence is absent in alternative splice products of h-Ets-1. PU1, the most distantly related member of the ets gene family, lacks this novel element. It has a distinct DNA-binding specificity that is determined by DNA sequences outside the core motif. These results have important implications for both the oncogenic and normal functions of ets family members.
