... promoters, mutation of the CHR leads to a more pronounced deregulation than the alteration of the CDE [40]. Another gene tested for its cell cycle regulation is the cellular inhibitor of apoptosis protein ... If the DREAM complex is the main regulator of CDE ⁄ CHR cell cycle genes, to which promoter sites does it bind during any par- ticular phase of the cell cycle? What is the exact mechanism of ... turns of the DNA double helix yields binding of the two or three NF-Y complexes on the same side of the DNA. Conservation of spacing is required for optimal pro- moter activity because changing the...
