Sir proteins impede, but do not prevent, access to silent chromatin in living Saccharomyces cerevisiae
Abstract Gene silencing at the mating-type loci in budding yeast (HMRa and HMLα) depends on the Sir proteins. Sir2, Sir3 and Sir4 are indispensable, whereas Sir1 has a limited role. Sir proteins are also involved in repression at telomeres and rDNA repeats. Sir proteins may mediate silencing by limi...
