摘要

A class of bent DNA is present in the genomic DNA of higher eukaryotes as a repeating unit (Kiyama, R., Gene Ther. Mol. Biol. 1, 641-647, 1998). This bent DNA appears once every 680 bp on average, and often shows periodicity, suggesting biological significance. By having a higher affinity for histone core particles, it has a role in designating a key nucleosome, which initiates nucleosome alignment. This modulates the enhancer activity of β- LCR and the silencer activity of the human β-globin locus and other loci. This suggests that this type of bent DNA plays important roles in various biological functions by affecting chromatin structure.
