General description

PPARG coactivator 1 α (PPARGC1A), a master transcriptional coactivator is a 91kDa multifunctional regulatory factor, encoded by the gene mapped to human chromosome 4p15.1. The encoded protein is mainly expressed in heart, skeletal muscle and kidney.

Application

Anti-PGC-1α(N-terminal) antibody produced in rabbit has been used in immunoblotting.

Biochem/physiol Actions

PPARG coactivator 1 α (PPARGC1α) integrates and regulates several metabolic pathways in response to external stimuli. PGC-1α regulates adaptive thermogenesis in brown adipose tissue and insulin signaling in skeletal muscle by activation of central metabolic and energy-related genes. It has a central role in the regulation of liver gluconeogenesis, β-oxidation of fatty acids and ketogenesis, by coactivation of key enzymes in the metabolic pathway, indicating that PGC-1α plays an important role as a global regulator of liver metabolism during fasting. PGC-1a is also a potent activator of mitochondrial biogenesis by coactivation of estrogen related receptor α(ERRα), nuclear respiratory factors (NRF)-1 and NRF-2. PGC-1a has been shown to suppress the generation of reactive oxygen species (ROS) and neurodegeneration by protecting neuronal cells from oxidative stress-mediated death. PGC-1α has been recently proposed to control muscle plasticity, to suppress broad inflammatory response and mediate the beneficial aspects of exercise.
