Biological Properties
General FunctionTranscription
Specific FunctionNAD-dependent histone deacetylase involved in telomeric silencing. Histone deacetylase proteins act via the formation of large multiprotein complexes that are responsible for the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. Restores silencing at HMR in SIR2 mutants when overexpressed. Required to repress middle sporulation genes during vegetative growth. Acts as a sensor of NAD(+) levels and regulator of NAD(+) biosynthesis. Regulates the gene expression of de novo NAD(+) biosynthesis genes
