Expression of the MYB gene is stimulated by binding of the RUNX1-containing TAL1 complex to the MYB gene enhancer (Sanda et al. 2012, Mansour et al. 2014). MYB transcription factor encoded by the MYB gene can bind to the RUNX1-containing TAL1 complex at the MYB gene enhancer to further facilitate MYB gene expression, thus creating a positive feedback loop (Mansour et al. 2014). In addition, somatic mutations at the TAL1 gene enhancer enable binding of the TAL1 complex containing MYB, RUNX1 and MYB-associated histone acetyltransferase CBP (CREBBP) to the TAL1 gene enhancer, creating a super-enhancer, which further amplifies the positive feedback loop involved in the MYB gene regulation (Mansour et al. 2014).
