There are a number of ELISA Kits available for the measurement of Estrogen-related Receptor gamma, another term for the human protein, estrogen related receptor gamma. Other synonyms may include: ERR gamma-2, estrogen receptor-related protein 3, nuclear receptor subfamily 3 group B member 3, ERR-gamma, ERRg, ERRgamma, and NR3B3. It is encoded by the ESRRG gene to yield a protein 458 amino acids in length and 51.3 kDa in size. However, there are up to 5 reported isoforms. The protein is categorized into the Nuclear hormone receptor family, NR3 subfamily. Versions of Estrogen-related Receptor gamma are present in other organisms, including: Mouse, Rat, Frog, Chicken.
