Lab

Western blot : Anti-ESRRA antibody (ab137489) staining at 1/1000 dilution, shown in green; Mouse anti-CANX [CANX/1543] (ab238078) loading control staining at 1/20000 dilution, shown in magenta. In Western blot, ab137489 was shown to bind specifically to ESRRA. A band was observed at 46 kDa in wild-type MCF7 cell lysates with no signal observed at this size in ESRRA knockout cell line. To generate this image, wild-type and ESRRA knockout MCF7 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

Supplementary information

Estrogen Related Receptor Alpha (ERRα) also known as NR3B1 is an orphan nuclear receptor with a molecular mass of approximately 51 kDa. It acts as a transcription factor and influences the expression of genes involved in energy metabolism. ERRα is expressed in numerous tissues such as the liver heart kidney and skeletal muscles. It binds to DNA as a monomer and alters specific gene expression activities. This protein lacks an identified ligand which classifies it as an orphan receptor but it shares structural similarities with estrogen receptors allowing the regulation of gene transcription in several physiological contexts.
Biological function summary

Estrogen Related Receptor Alpha regulates cellular energy production processes including mitochondrial biogenesis and oxidative phosphorylation. It plays a role in the biological function of energy homeostasis and increases the expression of genes related to metabolic processes. ERRα operates as part of a transcriptional regulatory network and interacts with other nuclear receptors and coactivators to modulate its activity. It often forms complexes with coactivators such as peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) to exert its effects on mitochondrial function.

Pathways

ERRα is integral to the PGC-1α signaling pathway and the AMPK (AMP-activated protein kinase) signaling pathway. These pathways are important in regulating energy metabolism and adaptive thermogenesis. ERRα interacts with PGC-1α to enhance mitochondrial function and energy expenditure while AMPK activation affects ERRα transcriptional activity and facilitates cellular energy balance. Additionally ERRα cross-talks with other nuclear receptors like PPAR (peroxisome proliferator-activated receptor) family members which are involved in lipid metabolism and glucose homeostasis.

ERRα has implications in metabolic conditions such as diabetes and obesity. The protein links to diabetes through its role in mitochondrial dysfunction and insulin resistance. Obesity-related studies point out how ERRα affects adaptive thermogenesis and lipid metabolism contributing to energy imbalance. ERRα-PPAR interactions highlight its association in metabolic disorders influencing various aspects of metabolism and disease progression. Understanding ERRα function offers therapeutic potential for targeting metabolic diseases.

Target data

Binds to an ERR-alpha response element (ERRE) containing a single consensus half-site, 5'-TNAAGGTCA-3'. Can bind to the medium-chain acyl coenzyme A dehydrogenase (MCAD) response element NRRE-1 and may act as an important regulator of MCAD promoter. Binds to the C1 region of the lactoferrin gene promoter. Requires dimerization and the coactivator, PGC-1A, for full activity. The ERRalpha/PGC1alpha complex is a regulator of energy metabolism. Induces the expression of PERM1 in the skeletal muscle.
