The transcriptional activator CLOCK is a histone acetyltransferase that is required for the
circadian expression of many genes. Asher et al.(2008) and Nakahata et al.(2008) now
demonstrate that the NAD+-dependent enzyme SIRT1 functions as a histone deacetylase
that counteracts the activity of CLOCK. These results broaden our understanding of the
impact of cellular metabolism on the circadian system.
