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]}
