Western blot analysis was performed on nuclear enriched extracts (30 ug lysate) of PC-3 (Lane 1), MCF7 (Lane 2), MDA-MB-231 (Lane 3) and whole cell extracts (30 ug lysate) of SK-OV-3 (Lane 4) and PC-12 (Lane 5). The blots were probed with Anti-Estrogen Related Receptor Rabbit Polyclonal (Product # PA1-314, 1-3 ug/ml) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product #A27036, 0.4ug/ml, 1:2500 dilution). A 45 kDa band corresponding to Estrogen- Related Receptor alpha was observed across the cell lines tested. Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 12 % Bis-Tris gel (Product # NP0342BOX), XCell SureLock™ Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane with iBlot® 2 Dry Blotting System (Product # IB21001). The membrane was probed with the relevant primary and secondary Antibody using iBind™ Flex Western Starter Kit (Product # SLF2000S). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

PA1-314 detects human ERR1 from transfected cells and shows no cross-reactivity to ERR3.
PA1-314 has been successfully used in Western blot and immunohistochemistry procedures. By Western blot, this antibody detects an ~52 kDa protein representing ERR1 from COS-7 transfected cells. An unidentified band is seen at ~37 kDa.
The PA1-314 immunogen is a synthetic peptide corresponding to the residues M(1) S S Q V V G I E P L Y I K A E(16) of human ERR1. This sequence is completely conserved between canine, human, mouse and rat. This immunizing peptide (PEP-231) can be used for neutralization and control experiments.
Estrogen-related receptor alpha 1 (ERR alpha, ERR1) is an orphan member of the nuclear hormone receptor superfamily. All the ERR family members share an almost identical DNA-binding domain, which has 68% amino acid identity with that of estrogen receptor.
This protein 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. Studies have shown that ERR1 functions a metabolic regulator and is often expressed in tissues that preferentially metabolize fatty acids.
The corresponding gene for the ERR1 is NR3B1.
