Peroxisome Proliferator-activated Receptor γ Co-activator 1α (PGC-1α) and Sirtuin 1 (SIRT1) Reside in Mitochondria

7 May 2010

Abstract excerpt

The transcriptional co-activator PGC-1alpha and the NAD(+)-dependent deacetylase SIRT1 are considered important inducers of mitochondrial biogenesis because in the nucleus they regulate transcription of nucleus-encoded mitochondrial genes. We demonstrate that PGC-1alpha and SIRT1 are also present inside mitochondria and are in close proximity to mtDNA. They interact with mitochondrial transcription factor A...
