Disease

[RUNX1_MOUSE] Note=Mice with an Runx1 lacking the DNA-binding region are found to die between embryonic days 11.5 to 12.5 due to hemorrhaging in the central nervous system. This hemorrhaging is preceded by necrosis and hematopoiesis is blocked.

Function

[RUNX1_MOUSE] CBF binds to the core site, 5'-PYGPYGGT-3', of a number of enhancers and promoters, including murine leukemia virus, polyomavirus enhancer, T-cell receptor enhancers, LCK, IL-3 and GM-CSF promoters. Essential for the development of normal hematopoiesis. Isoform 4 shows higher binding activities for target genes and binds TCR-beta-E2 and RAG-1 target site with threefold higher affinity than other isoforms. It is less effective in the context of neutrophil terminal differentiation. Acts synergistically with ELF4 to transactivate the IL-3 promoter and with ELF2 to transactivate the BLK promoter. Inhibits KAT6B-dependent transcriptional activation (By similarity).^[1] ^[2] [ETS1_HUMAN] Transcription factor.^[3] [PEBB_MOUSE] CBF binds to the core site, 5'-PYGPYGGT-3', of a number of enhancers and promoters, including murine leukemia virus, polyomavirus enhancer, T-cell receptor enhancers, LCK, IL3 and GM-CSF promoters. CBFB enhances DNA binding by RUNX1.

Publication Abstract from PubMed

Cooperative assemblies of transcription factors (TFs) on target gene enhancers coordinate cell proliferation, fate specification, and differentiation through precise and complicated transcriptional mechanisms. Chemical modifications, such as phosphorylation, of TFs induced by cell signaling, further modulate the dynamic cooperativity of TFs. In this study, we found that various Ets1-containing TF-DNA complexes respond differently to calcium-induced phosphorylation of Ets1, which is known to inhibit Ets1-DNA binding. Crystallographic analysis of a complex comprising Ets1, Runx1, and CBFbeta at the TCRalpha enhancer, revealed that Ets1 acquires robust binding stability in the Runx1 and DNA-complexed state, via allosteric mechanisms. This allows phosphorylated Ets1 to be retained at the TCRalpha enhancer with Runx1, in contrast to other Ets1 target gene enhancers including mb-1 and stromelysin-1. This study provides a structure-based model for cell signaling-dependent regulation of target genes, mediated via chemical modification of TFs.
