Regulation of telomere structure and functions by subunits of the INO80 chromatin remodeling complex.

ATP-dependent chromatin remodeling complexes have been implicated in the regulation of transcription, replication, and more recently DNA double-strand break repair. Here we report that the Ies3p subunit of the Saccharomyces cerevisiae INO80 chromatin remodeling complex interacts with a conserved tetratricopeptide repeat domain of the telomerase protein Est1p. Deletion of IES3 and some other subunits of the complex induced telomere elongation and altered telomere position effect.
