Peroxisome proliferator-activated receptor γ coactivator 1 (PGC-1)- and estrogen-related receptor (ERR)-induced regulator in muscle 1 (Perm1) is a tissue-specific regulator of oxidative capacity in skeletal muscle cells.

ABSTRACT: Mitochondrial oxidative metabolism and energy transduction pathways are critical for skeletal and cardiac muscle function. The expression of genes important for mitochondrial biogenesis and oxidative metabolism are under the control of members of the peroxisome proliferator-activated receptor γ coactivator 1 (PGC-1) family of transcriptional coactivators and the estrogen-related receptor (ERR) subfamily of nuclear receptors. Perturbations in PGC-1 and/or ERR activities have been associated with alterations in capacity for endurance exercise, rates of muscle atrophy, and cardiac function. The mechanism(s) by which PGC-1 and ERR proteins regulate muscle-specific transcriptional programs is not fully understood. We show here that PGC-1α and ERRs induce the expression of a so far uncharacteriz
