A New Splice Variant of the Mouse SIRT3 Gene Encodes the Mitochondrial Precursor Protein
30 Mar 2009
Abstract excerpt
BACKGROUND: Mammals have seven NAD-dependent protein deacetylases. These proteins, called sirtuins, are homologous to yeast Sir2, and are emerging as important regulators of lifespan and intermediary metabolism. Three mammalian sirtuins, SIRT3-5 are mitochondrial. Sirtuins are highly conserved between species, yet mouse SIRT3 was reported to be markedly shorter than its human counterpart and to lack the...
