Background
ERRβ/γ Antibody (E-1) is a high quality monoclonal ERRβ/γ antibody (also designated ERRβ/γ antibody) suitable for the detection of the ERRβ/γ protein of mouse, rat and human origin. ERRβ/γ Antibody (E-1) is available as both the non-conjugated anti-ERRβ/γ antibody form, as well as multiple conjugated forms of anti-ERRβ/γ antibody, including agarose, HRP, PE, FITC and multiple Alexa Fluor® conjugates. Estrogen and progesterone receptors are members of a family of transcription factors that are regulated by the binding of their cognate ligands. The interaction of hormone-bound estrogen receptors with estrogen responsive elements (EREs) alters transcription of ERE-containing genes. Estrogen receptor-related proteins (ERRα, β and γ) are orphan nuclear receptors. Like estrogen receptors, ERRs bind specifically to EREs to activate reporter genes. ERRβ, also known as steroid hormone receptor ERR2 or estrogen receptor-like 2, is expressed during mammary gland development and is critical in embryo development. The loss of ERRβ results in severely impaired chorion formation leading to placental failure and embryonic death. ERRβ also potently represses the transcriptional activity of Nrf2. ERRγ, also known as ERR3, is abundantly expressed in fetal heart. The loss of ERRγ results in lactatemia and death within the first week of life.
