===Crystal structure of Runx1 and Ets1 bound to TCR alpha promoter (crystal form 3)=== | |||
==Disease== | |||
[[http://www.uniprot.org/uniprot/RUNX1_MOUSE 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== | |||
[[http://www.uniprot.org/uniprot/RUNX1_MOUSE 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).<ref>PMID:8565077</ref> <ref>PMID:8622955</ref> [[http://www.uniprot.org/uniprot/ETS1_HUMAN ETS1_HUMAN]] Transcription factor.<ref>PMID:10698492</ref> | |||
