  1. ...at their 5′ ends by poly-T tracts and precisely at their 3′ ends by poly-A tracts. These tracts are also associated with nucleosome-free regions and are embedded with precisely positioned TATA boxes. Homo- and heteropolymeric tracts of A and T demarcate nucleosome border regions. Together, these findings...
  2. ...in highly active core promoters is focused within a narrow region, that poly(dA:dT) orientation has a functional consequence at the 3′ end of promoters, and that orthologous core promoters across yeast species have conserved activities. Our results demonstrate the importance of core promoters...
  3. ...the nucleosome occupancy data obtained from Field et al. (2009). We observed a nucleosome-free region (NRF) immediately upstream of TSS in constitutive core promoters (Fig. 4D; Supplemental Fig. S9). In contrast, the inducible core promoters generally are occupied with nucleosomes in the same region. Most...
