Cbf1p is required for chromatin remodeling at promoter-proximal CACGTG motifs in yeast.
Cbf1p is a basic-helix-loop-helix-zipper protein of Saccharomyces cerevisiae required for the function of centromeres and MET gene promoters, where it binds DNA via the consensus core motif CACRTG (R = A or G). At MET genes Cbf1p appears to function in both activator recruitment and chromatin-remodeling. Cbf1p has been implicated in the regulation of other genes, and CACRTG motifs are common in potential gene regulatory DNA. A recent genome-wide location analysis showed that the majority of i...Expand abstract
