(NaB) or trichostatin A (TSA) via p38 MAPK signaling. Thepalindromic G-CRE consensus, 5′-TGACGTCA-3′ is also an overlappingbinding site for cJun and other ATF family members [6]. This group oftrans-factors forms homo- or heterodimers such as CREB1/ATF-2when bound to DNA to achieve context-mediated gene activation orrepression in various promoters [7]. In our current study we sought toexplicate the role of cJun in γ-globin regulation through interactionwith other trans-factors bound to the G-CRE.
