Transcription Independent Insulation at TFIIIC-Dependent Insulators [PDF]

open access: yesGenetics, 2009
Abstract Chromatin insulators separate active from repressed chromatin domains. In yeast the RNA pol III transcription machinery bound to tRNA genes function with histone acetylases and chromatin remodelers to restrict the spread of heterochromatin.
