Overview
PGC-1 alpha a transcriptional coactivator for steroid receptors and nuclear receptors. Greatly increases the transcriptional activity of PPARG and thyroid hormone receptor genes. Interacts with, and regulates the activities of, cAMP response element binding protein (CREB) and nuclear respiratory factors (NRFs). Regulates many genes involved in energy metabolism. Provides a direct link between external physiological stimuli and the regulation of mitochondrial biogenesis, and is a major factor that regulates muscle fiber type determination. Plays an essential role in metabolic reprogramming in response to dietary availability through coordination of the expression of a wide array of genes involved in glucose and fatty acid metabolism. May be involved in controlling blood pressure, regulating cellular cholesterol homoeostasis, and the development of obesity. Its transcription is repressed by ZNF746 which binds to 'insulin response sequences' in its promoter. Heavily acetylated by GCN5 and biologically inactive under conditions of high nutrients. Deacetylated by SIRT1 in low nutrients/high NAD conditions. Note: This description may include information from UniProtKB.
