  • Title: ABFI contributes to the chromatin organization of Saccharomyces cerevisiae ARS1 B-domain.
    Author: Venditti P, Costanzo G, Negri R, Camilloni G.
    Journal: Biochim Biophys Acta; 1994 Nov 22; 1219(3):677-89. PubMed ID: 7948025.
    Abstract:
    The involvement of the ABFI transcription factor in organizing the chromatin structure of the Saccharomyces cerevisiae ARS1 region has been previously postulated. We studied the ARS1 chromatin structure both on the chromosome and on plasmids carrying wild type or mutated ABFI binding sites, using a recently developed no-background technique for nucleosome mapping, coupled with high resolution micrococcal nuclease in vivo footprinting. We show that ABFI protein acts as a boundary element of chromatin structure, by limiting the invasion by nucleosomes toward the essential A-domain.
