Repression of these genes occurs via the recruitment of the corepressors N-COR and SMRT due to their interaction with ETO. Mechanisms of RUNX1-ETO target gene upregulation remain less well understood. Here we show that RUNX1-ETO9a, the leukemogenic alternatively spliced transcript expressed from...
AML1-ETO9a lacks the C-terminal NHR3 and NHR4 domains of AML1-ETO and is highly leukemogenic in the mouse model. Here, we report that the AML1 DNA-binding domain and the ETO NHR2-dimerization domain, but not the ETO NHR1 domain, are critical for the induction of AML by AML1-...
RUNX1/AML1 DNA Binding Domain and ETO/MTG8 NHR2 Dimerization Domain Are Critical to AML1ETO9a Leukemogenesis Here, we report that the AML1 DNA binding domain and the ETO NHR2 dimerization domain, but not the ETO NHR1 domain are critical for the induction ... M Yan,S Hiebert,DE Zhang...
