DNA binding by the ETS protein TEL (ETV6) is regulated by autoinhibition and self-association.

The ETS protein TEL, a transcriptional repressor, contains a PNT domain that, as an isolated fragment in vitro, self-associates to form a head-to-tail polymer. How such polymerization might affect the DNA-binding properties of full-length TEL is unclear. Here we report that monomeric TEL binds to a consensus ETS site with unusually low affinity (K(d) = 2.8… (More)
