Autoinhibition of ETV6 (TEL) DNA binding: appended helices sterically block the ETS domain.
ETV6 (or TEL), a transcriptional repressor belonging to the ETS family, is frequently involved in chromosomal translocations linked with human cancers. It displays a DNA-binding mode distinct from other ETS proteins due to the presence of a self-associating PNT domain. In this study, we used NMR spectroscopy to dissect the structural and dynamic bases for the autoinhibition of ETV6 DNA binding ...
متن کاملDNA 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 x 10(-8) M). A deletion analysis demon...
متن کاملFusion of TEL, the ETS-variant gene 6 (ETV6), to the receptor-associated kinase JAK2 as a result of t(9;12) in a lymphoid and t(9;15;12) in a myeloid leukemia.
Translocations in hematologic disease of myeloid or lymphoid origin with breakpoints at chromosome band 12p13 frequently result in rearrangements of the Ets variant gene 6 (ETV6). As a consequence either the ETS DNA-binding domain or the Helix-Loop-Helix (HLH) oligomerization domain of ETV6 is fused to different partner genes. We show here that a t(9;12)(p24;p13) in a case of early pre-B acute ...
متن کامل12p abnormalities and the TEL gene (ETV6) in childhood acute lymphoblastic leukemia.
Although abnormalities involving the short arm of chromosome 12 (12p) are one of the most frequently observed rearrangements in childhood acute lymphoblastic leukemia (ALL), little is known about the frequency of different structural abnormalities and their relationship to the status of the ETV6 (also named TEL) gene in this region. Of 815 children with newly diagnosed ALL, 94 (11.5%) had a tot...
متن کاملBreakage and fusion of the TEL (ETV6) gene in immature B lymphocytes induced by apoptogenic signals.
TEL-AML1 fusion resulting from the t(12;21)(p13;q22) is one of the most common genetic abnormalities in childhood acute lymphoblastic leukemia. Recent findings that site-specific cleavage of the MLL gene can be induced by chemotherapeutic agents such as topoisomerase-II inhibitors suggest that apoptogenic agents can cause chromosomal translocations in hematopoietic cells. This study demonstrate...
