Abstract
The chromatin structure at a promoter can define how a gene is regulated. Studies of two yeast genes expressed in the G1 phase of the cell cycle, HO and CLN2, have provided important paradigms for transcriptional regulation. Although the SBF (Swi4/Swi6 box factor) transcription factor activates both genes, the chromatin landscapes that regulate SBF binding are different. Specifically, the CLN2 promoter is constitutively available for SBF binding, whereas HO has a complex two-step promoter in which chromatin changes in one region allow SBF to bind at a downstream location. These studies reveal the role of chromatin in defining the regulatory properties of promoters. 2013 Elsevier Ltd. All rights reservedEntities:
