Silencing provides a critical means of repressing transcription through the assembly and modification of chromatin proteins. The NAD(+)-dependent deacetylation of histones by the Sir2p family of proteins lends mechanistic insight into how SIR2 contributes to silencing. Here we describe three locus-specific sir2 mutants that have a spectrum of silencing phenotypes in yeast. These mutants are dep...
