Summary: Enables NAD-dependent histone deacetylase activity. Involved in several processes, including mRNA transcription; replication-born double-strand break repair via sister chromatid exchange; and subtelomeric heterochromatin formation. Predicted to be located in chromosome, telomeric region and cytoplasm. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Dec 2024]

This pathway is functionally relevant to TORC1 signaling since the stress sensitivity of a nonessential TORC1 mutant (tco89Delta) to hydroxyurea and arsenic can be reversed by combining tco89Delta with either hst3Delta, hst4Delta, or sit4Delta Surprisingly, while hst3Delta or hst4Delta rescues the sensitivity tco89Delta has to low concentrations of the TORC1 inhibitor rapamycin, sit4Delta fails to do so
