ERR-α (Estrogen-related receptor alpha, NR3B1) is an orphan nuclear receptor similar to the Estrogen Receptor. It is a sequence-specific DNA binding transcriptional activator that is constitutively active in the absence of ligand binding. No true physiological ligands have been found, but estrogen-like compounds from plants have been shown to activate ERR-α. ERR-α and ER-α have been found to regulate an overlapping set of genes, and ERR-α appears to modulate the activity of ER-α in some tissue types. ERR-α regulates genes involved in mitochondrial biogenesis, gluconeogenesis, oxidative phosphorylation, and fatty acid metabolism. ERR-α knockout mice display impaired fat metabolism and absorption.

Positive Control

Active Motif's MDA-MB-231 nuclear extract (Catalog No. 36080) can be used as a positive control for ERR-α antibody.


Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.
