AROuSing SIRT1: identification of a novel endogenous SIRT1 activator.
SIRT1 is a protein deacetylase that regulates cellular responses to a variety of stresses. In a recent issue of Molecular Cell, Kim et al. (2007) report the identification of a cellular protein, AROS, that activates the SIRT1-mediated deacetylation of p53.
